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();
  }
}
