• How to create JButton in Java

    In our previous post, we learned how to create a JFrame in Java. In this article, we will learn how we can create a jbutton in java and add it to our JFrame.

    The JButton is the class that is use to create a button in a JavaSE applications. Use JButton to send actions to your application whenever a user interacts with the button by either clicking, hovering, etc. Based from the official JavaDocs, a JButton is the actual implementation of a “push” button. It can be configured, and to some degree controlled, by¬†Actions. Using an Action¬†with a button has many benefits beyond directly configuring a button.

    Creating a Jbutton in Java Example

    package com.javapointers.javase;
    import java.awt.FlowLayout;
    import java.awt.event.ActionEvent;
    import java.awt.event.ActionListener;
    import javax.swing.JButton;
    import javax.swing.JFrame;
     * @author javapointers
    public class JButtonTest implements ActionListener{
        JFrame frame;
        JButton button;
        public JButtonTest(){
            frame = new JFrame();
            frame.setTitle("My JFrame");
            frame.setSize(500, 400);
            button = new JButton("Click Me!");
            frame.setLayout(new FlowLayout());
        public void actionPerformed(ActionEvent e) {
            System.out.println("You have click the button");
        public static void main(String args[]){
            JButtonTest test = new JButtonTest();

    When we run the program, it will show our JFrame with its JButton:

    jframe with jbutton

    and when the user click on the button, the string “You have click the button” will be displayed in the console.

    1. import javax.swing.JButton – import the JButton class to be able to use.
    2. button = new JButton(“Click Me!”) – Create a new instance of JButton with label Click Me!
    3. button.addActionListener(this) -Adds action when the user clicks the button.
    4. frame.setLayout(new FlowLayout()) – Define how java will layout your components. You will learn more about layout manager later on this tutorial.
    5. frame.add(button) – add the our button to the frame.
    6. public void actionPerformed(ActionEvent e) – the method that will be called when the user click the button.

    Now that we have learned on how to create a JButton in Java, our next topic will be on how we can create a JPanel in Java that can holds other components including the JButton that we just discussed.
