Class generic problem

For example: I have a class Abc
There is a Map, Map > mapping = new HashMap > ; ( ) ;

Class c = Class.forName (className) ;

if className The class is inherited Abc , it will execute the code below
mapping.put ("xxx", c); / / here is the problem

do not know if people understand what I mean, of course , if not generic , then it is not so much "dust " of the
------ Solution ---------- ----------------------------------

Since generics compile inspection , if without the usual cast with such wording is not compile the . We can use java generics only done at compile time checking features as long as we let the compiler can not check on the line, this time without a strong turn uses reflection to call put the best.

  package test;
  
  import java.lang.reflect.Method;
  import java.util.HashMap;
  import java.util.Map;
  
  public class Test {
  
  	public static void main(String[] args) throws ClassNotFoundException {
  
  		Map<String, Class<Test>> mapping = new HashMap<String, Class<Test>>();
  
  		String className = "xxx.xxx.xxx"; // 这里具体是什么并不重要
  
  		Class<?> c = Class.forName(className);
  
  		Method method=Map.class.getMethod("put",Object.class,Object.class);
                  method.invoke(mapping,"a",c);
                  System.out.println(mapping);
  	}
  }
  

------ For reference only ----------------------------------- ----
One might argue that such a solution
map.put ("xxx", (Class) c );

But the problem is "(Class ) c", forced conversion, it's not back to the way the non-generic ?

How to add a menu to the window ?

 This post last edited by proof1 on 2014-01-29 21:30:45

window as follows :

import javax.swing *;. import java.awt *;. import java.awt.event *.;

public class Test implements ActionListener {
public static void main (String [] args) {
JFrame win = new JFrame (" Practice " ) ;
win.setSize (900,900);
win.getContentPane () setBackground (Color.BLACK).;
win.setVisible (true);
}
}


want to add to the window menu bar . For example, a simplified example : file ( open exit ) view ( single-screen , full-screen )
reference code :
JMenuBar menubar = new JMenuBar ();
JMenuItem anItem;

JMenu menu1 = new JMenu (" File" ) ;
anItem = new JMenuItem (" Open "); menu1.add (anItem); anItem.addActionListener (this);
anItem = new JMenuItem (" Exit "); menu1.add (anItem); anItem.addActionListener (this);

JMenu menu2 = new JMenu (" View" ) ;
anItem = new JMenuItem (" single screen "); menu2.add (anItem); anItem.addActionListener (this);
anItem = new JMenuItem (" fullscreen "); menu2.add (anItem); anItem.addActionListener (this);

menubar.add (menu1);
menubar.add (menu2);


How to add a menu bar to the window ? Please use two ways
One is to add code directly in the menu window .
Another is to clear structure , so the menu independent . Create a new menu category , then add a menu to the window object .

I got to try

How to write a lot of two-way relationship here ? Seeking to rationalize the idea

model : customers, orders , rooms , schedule



The first process:
guests submit an order to form an order object , order room contains objects object , the client object , schedule objects.

now proposed :

room objects

  public class Room
  {
  	private long id;
  
  	private String name; // 房型名称
  
  	private Float price; // 挂牌价
  	private Float realPrice; // 现售价格
  
  	private int breakfast; // '1':'含早餐','0':'无早餐'
  
  	private String info; // 简介
  

target customers

  public class Customer
  {
  	private long id;
  
  	private String realName;
  	private int gender; // '1':'男','0':'女'
  
  	private String identity; // 用户身份证号
  	private String nationality; // 用户国籍
  	private String address;
  
  	private String phone;
  	private String email;
  

schedule object

  public class Schedule
  {
  	private int id;
  
  	private Date orderDate;
  
  	private Date beginDate;
  
  	private Date endDate;
  

rationalize these comparisons , the corresponding hbm has also been established.



problem is now [ Order objects:

  public class Book
  {
  	private int id;
  
  	private Room room; // 客房
  
  	private Customer customer; // 客人信息
  
  	private Schedule schedule; // 日程
  

hbm not very clear that how to write , the idea is a bit of :
middle of the table is to use as many relationships in the Orders table .
but rooms can not be deleted ( the total amount of room on the hotel all that much ) , guest information can not be deleted ( guest history data ) , the schedule may be to clear ( schedule over several years of data can be deleted in the second schedule stages of development time and mobility might be a relationship , schedules and room objects in addition to a relationship , it will also provide tables and dining a relationship , a relationship and meetings arranged . )




These are now the first self- written program processes card to order here.





============================================== ============================================

An order may contain multiple clients , you need two people to live two guest information , guest information so I will change the order later collection.


out of the process to see outside.

a customer will contain multiple orders , an order will also contain a number of customers. ( Speaking here only for the room , do not take account of Meetings Orders )






============================================== ================

So I think the point here is his knowledge of the leak , do not write this hbm file , or modeling wrong.


two objects -many relationship , I would write , but how to write three objects -many relationship , accurately say how to form an intermediate table .
table structure like this :

middle table ID \ room table foreign key ID \ Guest Information foreign key ID \ schedule a foreign key ID








============================================== =========================
but I do not think I'm wrong , because I found the time to write and schedule an object when the object collaboration room when you can achieve control daily housekeeping work in this business ( that is a total of 20 such as Double , 1 enough 20 between the time can not be sold , the 2nd had 12 points after restored to 20 )

------ Solution ------------- -------------------------------
suggest you look at the last hibernate document best practices , does not recommend the use of multi- for many , unless absolutely necessary !
------ Solution ---------------------------------------- ----
personally think that it is not necessary to configure this relationship . In the table there is any relationship to each other only save id on it, I need to use to get the associated record according to id .
In addition , 6th Floor, said contrary to hibernate learning purposes, this really does not. Really, the project is how quick and easy how to , but if you do it faster and better than using hibernate , then why do you have to use it too , because you are in the project using the hibernate it? To improve the efficiency of the tool . Like Xiao Ming and Zhang apart than the two 10 m yuan , each have a car , do not say it because a car , you must drive to go?
------ For reference only -------------------------------------- -
are not many relationships , should not go to room table , guest tables, schedules three table relationships


Instead, three relationships were established : Doula
Orders table with room table ( order date corresponds with a different room , an order can only be developed under a single chamber. )
Orders table -many table with guests
Orders table and the schedule of many-
------ For reference only -------------------------- -------------
Well, I now want to understand the point, seems to be the order of business logic , it is basically impossible to insert mounted directly SPRING Well , only in the business layer first realized the insertion schedule to get the schedule 's OID then insert orders.


But the order object is not to waste in order to remove what should be assembled when the object of it . Attempt. . . . . Later posted to another question or knot .

friend so, give a very simple example yesterday I tried to write it:

Users
team

A user can be in multiple groups, one group can have multiple users
============================================== =
database has users \ user_group \ groups of three tables

operations will be conducted as follows :
delete users watch users while removing user_group tables and user-related records, but to be able to keep groups table corresponds to the organization ;
delete groups table tissue while removing user_group tables and records related to the organization , but to be able to keep users table users ;
============================================== =
I think this is a typical many.

Now I'm confused a little something like this:
I can write two hbm, realized the middle of the table is automatically generated , but the operation can only be achieved when my own part of the operation , this is the place incomprehensible .

code is as follows :

  <?xml version="1.0"?>
  <!DOCTYPE hibernate-mapping PUBLIC "-//Hibernate/Hibernate Mapping DTD 3.0//EN"
  "http://hibernate.sourceforge.net/hibernate-mapping-3.0.dtd">

  			<many-to-many class="bean.User" column="user_id"></many-to-many>
  		</set>
  		
  	</class>
  
  </hibernate-mapping>
  

  <?xml version="1.0"?>
  <!DOCTYPE hibernate-mapping PUBLIC "-//Hibernate/Hibernate Mapping DTD 3.0//EN"

  		</id>
  	
  		<property name="username" column="username" type="string"></property>
  		<property name="password" column="password" type="string"></property>
  		
  		<set name="groups" table="user_group" cascade="save-update">
  			<key column="user_id"></key>
  			<many-to-many class="bean.Group" column="group_id"></many-to-many>
  		</set>
  		
  	</class>
  
  </hibernate-mapping>
  
  

  		 //添加数据:正确实现添加内容
  		 User user1 = new User();
  		 user1.setUsername("zhangsan");
  		 user1.setPassword("123456");
  				
  		 Group group1 = new Group();
  		 group1.setGroupName("组一");
  				
  		 user1.getGroups().add(group1);
  		 group1.getUsers().add(user1);
  
  		 UserDAO userDAO = new UserDAOImpl();
  		 userDAO.save(user1);
  
  		//测试二:删除用户，可以实现删除中间表记录
  		// UserDAO userDAO = new UserDAOImpl();
  		// User user1 = userDAO.findUserById(1);
  		// userDAO.removeUser(user1);
  
  //测试三：删除组，不能删除组，也不会删除中间表相关记录
  //		GroupDAO groupDAO = new GroupDAOImpl();
  //		Group group1 = groupDAO.findGroupById(1);
  //		
  //		System.out.println(group1);
  //		
  //		groupDAO.removeGroup(group1);
  

Now my difficulty is in the actual development is how to deal with such problems ?
because I can not hbm to manage this relationship , but only manage each corresponding model Tim excision investigation, and then go to their calling in the business layer dao to complete three different functional requirements .
something to do so I was very relaxed , but always felt that this is not contrary to hibernate for learning purposes ?

Thank you, I have access to official documents , where you say , understand !
official recommendation : split into two many, most of the time need to connect the table to add additional information.

And this is what prompted my page perplexing question .
At this point, the front solved the same problem !


Do not use exotic association mappings:
Practical test cases for real many-to-many associations are rare. Most of the time you need additional information stored in the "link table". In this case, it is much better to use two one-to-many associations to an intermediate link class. ;. In fact, most associations are one-to-many and many-to-one For this reason, you should proceed cautiously when using any ;. other association style

Well , thank you, I understand, I previously thought hibernate in addition to help complete object into the database , but also reflected in the hbm possible mutual relationship, and by substituting treatment hibernate .

now, although not express it, but it seems more aware of the point .

chose this because it finished SSH2 integrate learning , if disarray side processing , write well hbm file , the next step would not be able hbm file as a resource into the spring configuration file.

past six months I have to look for a solution.

more than a year before he wrote a lot of code that can be said for generations .
front from the beginning of writing HTML + CSS + JS start
Later in the maintenance of soft , U8 database SQL SERVER2000
background and then later write ASP code and the kind of language mixing ( to launch late simply pull a body, they did not write my own method modified ) After
PHP and then later saw the video section , starting with a simple MVC pattern to write , but too fragmented (perhaps as a mature language has its own solution , but I did not stick to it ) .
Later that because of the mobile client , write your own copy or imitate a android client to the unit used ( in which the video made ​​strong Java the language ) , due to the presence android client , their scope of work expand again , multilingual maintenance as a person who is largely my burden , but also understand what they do best is to deal with that piece of content.

( front than I'm good , because they belong to a perfectionist , always in front of their own are unable to meet their own doing now want to think, so give up ; database side , then put it crudely , Stuck cases , also so many things ; so that business last block of )

So six months looking at Java tutorial, I locate their position further , try to use other aspects of the mature thing to do instead of their own , after reading the SSH2 integration can be said to be excited , because finally find their focus a .

executorService = Executors.newScheduledThreadPool (1) on a thread of it this way makes sense it?

  thread   thread pool

executorService = Executors.newScheduledThreadPool (1);

above , on one thread only, it is also necessary to use the thread pool , direct new thread and then start not enough , there is the difference? Seeking advice.
------ Solution ---------------------------------------- ----
Note that threads in the pool can be reused , and what new Thread , exhausted gone.

1 ex useful , only one thread can be restricted to work .
------ Solution ---------------------------------------- ----
create threads and destroying threads are the need of time. Performance is not high , read this article

Bs development life can only do CRUD ?

too depressed to work every day are repetitive CRUD
------ Solution ------------------ --------------------------
if the additions and deletions to consider the efficiency and performance , there is a lot of content you can learn. I suggest you start from the basic algorithm.
------ Solution ---------------------------------------- ----
CRUD is the vast number of books in the world system are doing things , this is not your fault
you have to do something very core , the next step is how to do !
want finally , think if thousands , tens of thousands, hundreds of thousands , millions of people online at the same CRUD with you
system , you do not crash is very good !
------ Solution ---------------------------------------- ----
found
You're asking the wrong question, my friend.
Don't blame the CRUD for all the bullshit that is often associated with it.

(Reminder: CRUD stands for Create Retrieve Update Delete, and is the underlying philosophy for the database applications that run the world ; we live in, the 90% of the iceberg that most hackers never see or even think about).

I've been doing CRUD for 33 years and it's been an incredible ride. I credit my CRUD work for putting me in the right hand 5% of that bell curve, ahead of the rest of my fellow hackers who have built so little of substance.

Sure, I've built apps that move people and things to the right place, and also have done a lot of "reports here, manage documents here, upgrade calender software here", but what job doesn't have some crap work go to along ;? with the gravy I've never seen any good job without it's share of maintenance, refactoring, testing, process, and meetings ; with drones.

I've also build software that generates other software, invented new frameworks, and devised algorithms that dramatically improved the way we make and build and move the stuff that's probably in your cubicle right now. I've taken cool academic theory from my pure mathematical background to build software that has blown away the posers everywhere around me. And you know what? You do that just once, and every champion in the enterprise runs to you with their giant budgets to solve their CRUD problem du jour with your "genius".

Believe me, you don't have to work at "Intel, Google, Apple, or NASA" to "change the world ". You're just as likely to be a cog in the wheel at those places as anywhere else.

You can change the world from where ever you're at, and in fact, if you're working on a CRUD app, I think you're actually in a better position to do it. You just have to ask a better question.

My suggestion: "How to you escape the shackles and bullshit of your CRUD job and use all those great resources in your head to turn that job on its side and change the world from right where you're at? "

Find the answer to that question. It may be easier than you think.


------ Solution ------------------------------------ --------
upstairs positive solution. Ide light to do the windows platform to put forward what's it mean to you CRUD
1 have time to study under the data structures and algorithms , try them with C / Java to write out
doing development , the most important algorithms
If you only do something with API jdk provided , the road will be very narrow

2 put java programming ideas read , write code , which allows a more solid basis for Java
3 look at the book Design Patterns , many companies are now asking those who love stuff

4 can take your technology involved in-depth understanding of the next

5 see Linux book, as a programmer is not a senior Linux unskilled

6 to see a high-performance , distributed Hadoop cloud computing cluster continuous integration , etc.

7 at least learn a scripting language , outside of Shell, you can look at Python. Many large cattle use it to write gadgets

PS: Java programmers to engage in a solid first base or the most important.
PPS: BS development , then the front end is very important , javascript cattle fork with people who would be a good mix of yo , after all, most companies do not have a dedicated team of JS

------ For reference only ------------------------------- --------
all businesses need to deal with data that help users to manage data. Of course, some other functions , but it is also the main data . That data is CRUD , SQL so many years of data operations are still only INSERT, DELETE, UPDATE, SELECT. All data are based on the system as a basis . Regardless of uploading and downloading , importing and exporting , including opening PDF, DOC and other documents , and so on ... that does not require data to support it? So do not blame only the CRUD, because those are the core of the system of things. C / S structure is not also one of those thing. Your long way to go , come slowly . If you feel depressed now , I suggest you wrap it.

JAVA and sentiment analysis

  java   emotion

graduation design done on sentiment analysis , such as: the input sentence , judgment or criticism praised . Experts who have nothing to disclose what information and technology ?
------ Solution - -------------------------------------------
this a bit difficult, first word , then estimated to be combined with contextual semantics. . .
------ Solution ---------------------------------------- ----
this idea I have is for the landlord reference : Get the input string , and then parse the string , and then create a string array , the array included all the words used to describe the mood of people , word , phrase , and then provide an array of strings each string and input is compared to criticize or judge praised ...
------ Solution ---------- ----------------------------------
the whole into a thesaurus related words starting treatment ah
