[Abhimanyus singh]

import java.awt.Container;
import java.awt.Dimension;
import javax.swing.JFrame;
class MyFrame extends JFrame
{
MyFrame(String h)
    {
    super(h);
    this.setSize(200, 200);
    this.setResizable(false);
    //setLocationRelativeTo(null);
    Container content=this.getContentPane();
    content.setLayout(null);
   
    
    this.setVisible(true);
    }
}

class Main1
{
    public static void main(String args[]) 
    {
     MyFrame frame=new MyFrame("This frame");
	
    }
}

Every time I run this code, it results into a maximized frame, occupying the screen completely, I'm confused why is this happening ?? PLease help !!!
