Create a Java application that paints a square. The user specifies the position and size of the square by positioning and clicking the mouse twice, once for the upper left corner of the square and once for the lower right corner.


I got the square and I got the mouse click input working but I'm not sure how to move the square.

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



  public class JavaSquare extends JApplet implements MouseListener  
  {		
  int height=20;
  int width=20;
  int x=10;
  int y=10;

	  public void paint(Graphics g )
  	  {
	     g.setColor(Color.red);
  	     g.drawRect(10,10,height,width);
  	     g.setColor(Color.blue);
  	     g.fillRect(x,y,height,width); 
  	  }
  public void Frame()
    {	  
	      JFrame frame = new JFrame("Java Square Assignment");
     	  frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
    	  frame.setSize(400,400);
    	  frame.setVisible(true);
    	  frame.setLocationRelativeTo(null);
    	  frame.setLayout(new BorderLayout());
    }
 public JavaSquare()
 {
   addMouseListener(new MouseAdapter()
   {
   public void mouseClicked(MouseEvent e) 
   {
	   System.out.println("Mouse clicked; # of clicks: " + e.getClickCount() );
     if (e.getClickCount() == 2) 
    		{
    	 
    		}
   }
   
    }); 
 }
  	
	}

You wont be able to use getClickCount for what you want.

You could have a boolean value indicating which corner to change
Like so:

public void mouseClicked(MouseEvent e) {
	if (positionTopLeftCorner) {
		topLeft = new Point(..., ...);
	}
	else {
		...
	}
	
	positionTopLeftCornor = !positionTopLeftCornor;
}
