Java Rectangle

[java_beginner_]

Hello,
I have another question.
I can make a rectangle in Java but the output is this:



This is my code:

/*

Name: Window
Filename: Window.java

*/

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

public class Window extends JFrame {

	public Window() {
	
		setTitle("Window");
		setSize(600, 400);
		setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
		getContentPane().setBackground(Color.WHITE);
		setVisible(true);
		
		
	
	}
	
	public void paint(Graphics g) {
		
		g.drawRect (10, 10, 200, 200);  
	
	}
	
	
	public static void main(String[] args) {
	
		Window w = new Window();
	
	}

}

Thanks!

What is your question? b.t.w. you should override the paintComponent( ... ) method, not the paint( ... ) method.

kind regards,

But he'll need to override paintComponent for a JPanel not for the JFrame since it doesn't have this method.

Yep, I missed that one completely; thanks for pointing that out (it's Sunday so I'm forgiven ;-)

kind regards,

Let's see a compilable/runnable program.

huh, what do you mean?

[java_beginner_]

here is my code

/*

Name: Window
Filename: Window.java

*/

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

public class Window extends JFrame {

	public Window() {
	
		setTitle("Window");
		setSize(600, 400);
		setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
		getContentPane().setBackground(Color.WHITE);
		setVisible(true);
		
		
	
	}
	
	public void paintComponent(Graphics g) {
		
		g.drawRect (10, 10, 200, 200);  
	
	}
	
	
	public static void main(String[] args) {
	
		Window w = new Window();
	
	}

}

Again, you should not do this in a JFrame and again JFrame has no paintComponent method. Again, do this in a JPanel and then place that JPanel into a JFrame. Please read a tutorial, any tutorial, on Swing graphics, starting with the standard oracle tutorial as it will explain a lot to you.

In general, avoid using class names that clash with the standard JDK classes. In this case, Window is an exceptionally inappropriate choice, since javax.swing.JFrame extends java.awt.Frame, which in turn extends java.awt.Window.
