窗口应用程序无法在Eclipse中打开

Question

Hi I am trying to learn java. I wrote a code which opens the string in window but actually it is not opening.

import java.awt.Frame;
import java.awt.Graphics;
import java.awt.event.WindowAdapter;
import java.awt.event.WindowEvent;

public class Test extends Frame {
    public void paint(Graphics g){
        g.drawString("Hello from Java",60,100);
    }


public static void main(String args[]){
    Test f = new Test();
    f.setSize(200,200);
    f.addWindowListener(new WindowAdapter(){
        public void windowClosing(WindowEvent e){
            System.exit(0);}});
}
}

Thanks in Advance

You have to set it to be visible , using setVisible() :

Test f = new Test();
f.setVisible(true);
