JAVA BASIC BUTTON

Now that you have created your window, lets add something to it.

1. Create a JButton (above the main method, not inside)

    public static JButton button;
   

2. Instantiate in the main method

   • JButton takes a String argument of the text

     button = new JButton("BUTTON");
     

3. Set the button's bounds (X, Y, Width, Height)

      button.setBounds(20,20,200,100);
   

4. Set the action listener

   • Action listeneners can be a bit difficult to understand

   • To add functionality to a button give it a new action listener, then define what it does under actionPerformed

     button.addActionListener(new ActionListener() {
     
           @Override
           public void actionPerformed(ActionEvent e) {
               System.out.println("Button Clicked!!!");
           }
     
     });
     

5. Add the button to the frame

    frame.add(button);
   

6. Test your app. Try adding more buttons and play around a bit :D
