Please help me to see one of this calendar output program , the output bit of a problem , I do not know how to change

Output format is a little wrong, check a long time, I do not know where the problem lies , please help.

import java.text.DateFormatSymbols;
  import java.util.*;
  
  public class Test
  {
  	public static void main(String[] args)
  	{
  			
  			String[] weekdayNames = new DateFormatSymbols().getWeekdays();
  			for(int i=1; i<=7; i++)	
  			{		
  			  System.out.print(weekdayNames[i]);
  			  System.out.print(" ");
  		  }
  		  System.out.println();
  		  
  		  
  		  GregorianCalendar calendar = new GregorianCalendar();
  		  int firstDayOfWeek = calendar.getFirstDayOfWeek();
  		  calendar.set(Calendar.DAY_OF_MONTH, 1);
  		  int weekday = calendar.get(Calendar.DAY_OF_WEEK);		
  		   int blank = 0;
  		   while(weekday != firstDayOfWeek)
  		   {
  		   		blank++;
  		   		calendar.add(Calendar.DAY_OF_MONTH,-1);	
  		   		weekday = calendar.get(Calendar.DAY_OF_MONTH);	   		
  		   }
  		   
  		   for(int i=0; i<blank; i++)
  		   {
  		   		System.out.print(" ");	
  		   }
  		   
  		   int month = calendar.get(Calendar.MONTH);
  		   calendar.set(Calendar.DAY_OF_MONTH, 1);
  		   int day = calendar.get(Calendar.DAY_OF_MONTH);
  		   System.out.printf("%7d", day);
  		   calendar.add(Calendar.DAY_OF_MONTH, 1);
  		   while(calendar.get(Calendar.MONTH) == month)
  		   {		   		   				   				   		
  		   		weekday = calendar.get(Calendar.DAY_OF_WEEK);
  		   		if(weekday == firstDayOfWeek)
  		   		{
  		   				System.out.println();	
  		   		}
  		   		day = calendar.get(Calendar.DAY_OF_MONTH);	   		
  		   		System.out.printf("%7d", day);
  		   		calendar.add(Calendar.DAY_OF_MONTH, 1);			   			   		
  		   }		   
  	}	
  }
  

my program output is so



but it should be transferred in the next line when the 3rd fishes , but did not change jobs, I do not know why, of course, is certainly due weekday == firstDayOfWeek not established , but my program should be the 3rd time weekday == firstDayOfWeek set up properly, I do not know why not set up , did not go to the next line ?

existing is November , the computer displays the arrangement should be

So I do not know why the program arranged incorrect ?
------ Solution ---------------------------------------- ----


operation above you change the value of your calendar to get the month is not November , and should be able to reset the next .

calendar.setTime (new Date ());
int month = calendar.get (Calendar.MONTH);
calendar.set (Calendar.DAY_OF_MONTH, 1);

why the picture does not show , Zaifayici ,

This is my own output.
------ For reference only -------------------------------------- -
no attention to me ? This is the first time I encountered such a long time did not respond to me.
------ For reference only -------------------------------------- -
really is the month is wrong. I changed a bit , you can output the correct form .

import java.text.DateFormatSymbols;
  import java.util.*;

  			{		
  			  System.out.print(weekdayNames[i]);
  			  System.out.print(" ");
  		  }
  		  System.out.println();
  		  		  
  		  GregorianCalendar calendar = new GregorianCalendar();
  		   	  
  	  int firstDayOfWeek = calendar.getFirstDayOfWeek();
  		  int month = calendar.get(Calendar.MONTH);

  		   {
  		   		System.out.print(" ");	
  		   }		   
  
  		   calendar.set(Calendar.MONTH, 10);	   	//此处是与第一次贴出的程序不同之处。	   
  		   calendar.set(Calendar.DAY_OF_MONTH, 1);
  		   		   
  		   int day = calendar.get(Calendar.DAY_OF_MONTH);
  		   System.out.printf("%7d", day);
  				calendar.add(Calendar.DAY_OF_MONTH, 1);	
  		   while(calendar.get(Calendar.MONTH) == month)
  		   {		   		   				   				   		
  		   		weekday = calendar.get(Calendar.DAY_OF_WEEK);
  		   		if(weekday == firstDayOfWeek)
  		   		{
  		   				System.out.println();	
  		   		}
  		   		day = calendar.get(Calendar.DAY_OF_MONTH);	   		
  		   		System.out.printf("%6d", day);
  		   		calendar.add(Calendar.DAY_OF_MONTH, 1);			   			   		
  		   }		   
  	}	
  }
  

correct output in the form of
