Java Swing

Swing is the principal GUI toolkit for the Java programming language. It is a part of the JFC (Java Foundation Classes), which is an API for providing a graphical user interface for Java programs. It is completely written in Java.

import java.awt.EventQueue;
import javax.swing.JFrame;

public class SimpleEx extends JFrame {

    public SimpleEx() {

        initUI();
    }

    private void initUI() {
        
        setTitle("Simple example"); //window title
        setSize(300, 200); //size window
        setLocationRelativeTo(null);
        setDefaultCloseOperation(EXIT_ON_CLOSE);
    }

    public static void main(String[] args) {

        EventQueue.invokeLater(new Runnable() { //This method will close the window if we click on the close button of the titlebar
        
            @Override
            public void run() {
