A Window Frame In Java

There are two kinds of programs in Java. One that runs on the commandline. The other runs as a GUI. Today we'll be focusing on GUIs.

In order to work with a GUI, first you need to create a window. We use a JFrame in order to do this.

import javax.swing.JFrame;public class Window extends JFrame {  public Window() {    super("My Window");    setSize(640, 480);    setResizable(false);    setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);    setLocationRelativeTo(null);    setVisible(true);  }  public static void main(String[] args) {    new Window();  }}
