How to create a GUI application in Java?

Creating a Graphical User Interface (GUI) application in Java involves several steps. Here is a basic outline of the steps involved:

  1. Choose an IDE: Select an Integrated Development Environment (IDE) for Java, such as Eclipse or NetBeans, to create a Java project.
  2. Create a Java Class: Create a Java class that extends the JFrame class, which is used to create a window in Java. The JFrame class provides a container for other GUI components.
  3. Add GUI Components: Use Java Swing or JavaFX libraries to add GUI components to the JFrame. Examples of GUI components include buttons, text boxes, labels, and menus.
  4. Set Layout: Set the layout for the JFrame using a Layout Manager, which arranges the GUI components on the window.
  5. Add Event Listeners: Add event listeners to the GUI components to handle user interactions, such as button clicks or menu selections.
  6. Compile and Run: Compile and run the Java code to create the GUI application.

Here is some sample code to create a simple GUI application in Java:

import javax.swing.*;

public class MyGUIApplication extends JFrame {

    public static void main(String[] args) {
        MyGUIApplication myGUIApp = new MyGUIApplication();

    public MyGUIApplication() {
        setTitle("My GUI Application");
        setSize(300, 300);

        JLabel label = new JLabel("Hello, World!");

This code creates a window with a title, sets the size and location of the window, and adds a label to the window. When the code is compiled and run, the GUI application is displayed on the screen.
