Hi friend,

Use the following code:

import javax.swing.*;
import java.awt.*;
import java.awt.event.*;
import javax.swing.border.Border;
public class AB extends JDialog{
public AB(JFrame frame, String str){
super(frame,str);
setUndecorated(true);
getRootPane().setWindowDecorationStyle(JRootPane.NONE);
addWindowListener(new WindowAdapter(){
public void windowClosing(WindowEvent evt){
System.exit(0);
}
});
}
public static void main(String[] args){
try{
AB frame = new AB(new JFrame(),"");
JPanel panel = new JPanel();
Border border = BorderFactory.createTitledBorder("Welcome");
panel.setBorder(border);
JLabel lbl = new JLabel("RoseIndia");
panel.add(lbl);
frame.add(panel);
frame.setSize(300, 150);
frame.setVisible(true);
}
catch(IllegalArgumentException e){
System.exit(0);
}
}
}
Thanks
