package guiprojj; 

import javax.swing.*; 

public class gui { 
    public static void main() 
    { 
     JFrame maingui = new JFrame("Gui"); 
     JPanel pangui = new JPanel(); 
     JTextField movie = new JTextField(16); 
     maingui.add(pangui); 
     pangui.add(movie); 
     maingui.setVisible(true); 
     maingui.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE); 
    } 
}
