What is the method to achieve the air ?

The following procedure is wrong , one is prompted to "Test.java: 63: error: parse have reached the end of file
} ", but I checked , there is no lack of" } "Ah , another run to remind all the methods of abstract classes not covered , but I think not cover , I checked Baidu , said you can empty achieve , ask me how empty this program implements the abstract method in a class ?

import java.util.*;
  
  public class Test
  {
  	public static void main(String[] args)
  	{			
  			Employee[] employee = new Employee[2];
  			employee[0] = new A("ert", "computer");
  			employee[1] = new B("rty", 5000);
  			
  			for(Employee i: employee)
  			{
  				System.out.println(i.getName()+","+i.getMajor()+","+i.getSalary());	
  			}
  
  	}	
  }
  
  abstract class Employee
  {		
  		private String name;
  		
  		public Employee(String n)	
  		{
  			name = n;						
  		}
  	
  	  public String getName()
  	  {
  	  	return name;	
  	  }
  		
  		 public abstract  String getMajor();
  		 public abstract double getSalary();
  }
  
  class A extends Employee
  {
  		private String major; 
  		public A(String n, String m)
  		{
  			super(n);
  			major = m;
  		}
  		public String getMajor()
  		{
  			return major;	 	 
  }
  
  class B extends Employee
  {
  		private double salary;
  		public B(String n, double x)
  		{
  			super(n);
  			salary = x;	
  		}	
  	
  		public double getSalary()
  		{
  			return salary;	
  		}	
  }

------ Solution ------------------------------------- -------

  class A extends Employee
  {
          private String major; 
          public A(String n, String m)
          {
              super(n);
              major = m;
          }
          public String getMajor()
          {
              return major;          
          }//这里少个括号
  }
  

------ Solution --------------------------- -----------------
class A getMajor way less of a "}" ;
classes A and B have one less implemented method
------ Solution ------------------------- -------------------
is no specific method body .
------ Solution ---------------------------------------- ----
empty implementation is nothing to write within the {}
------ Solution ----------------------- ---------------------


landlord to see red font , you are the method's return value is double , the method must return a value,
can write public void getSalary {

} Try

Do not forget to settle landlord posted

Thank you, indeed one less } , in addition, A and B of the method less , how to make it? , The procedure variables in each class is fixed.

If nothing written inside { } will appear this error message " missing return statement ." In the A category is what I added

public double getSalary()
  		{
  			
  		}

------ For reference only ---------------------------------- -----
public void getSalary () {

}

Sorry , fewer parentheses

8 floor would not work . There will be " not covered by the abstract class method " error .

I generally Results posted soon , is waiting for the answer, this post I will end up with it. After more study, the more other , perhaps solved.

I suggest you come to my blog to download a project examples , I believe you learn more help , which has a general usage
------ For reference only ---------------------------------------
you those methods have return values Therefore, the implementation is empty
public double getSalary () {
return null;
}

shadowsick, go to your blog to read, I was just entering JAVA, looking very basic knowledge , understand your project a little more difficult , my collection , and hope that their knowledge can be achieved after easy to understand the extent of your project . Thank you.

landlord, you do not quote you, we can not see your reply
