Help with JButton please.

[jean28]

First of all, I am extremely new to JButtons. I have watched a tutorial online and saw the basics of how it works, but the example I have only displays a message in the screen and I want to use the JButton for a different function than displaying text.

I want to put an if statement INSIDE each of the 2 JButtons that pop on the screen. Short example (not actually in java, but what I am trying to do):

if (button 1 is pressed)
{
perform certain actions
}

else if (button 2 is pressed)
{
dont perform actions and go back to how it was before pressed
}


This is the simple JButton program I have made. Any help or any link to a tutorial would be HUGELY appreciated. Thank you very much.

import java.awt.FlowLayout;
import java.awt.event.ActionListener;
import java.awt.event.ActionEvent;
import javax.swing.JFrame;
import javax.swing.JButton;
import javax.swing.Icon;
import javax.swing.ImageIcon;
import javax.swing.JOptionPane;

public class Gui extends JFrame 
{
	private JButton reg;
	private JButton custom;
	//private JButton custom;
	
	public Gui ()
	{
		super("The title");
		setLayout(new FlowLayout());
		
		reg = new JButton("Check");
		custom = new JButton("Pass");
		add(reg);
		add(custom);
		
		
		HandlerClass handler = new HandlerClass();
		reg.addActionListener(handler);
		custom.addActionListener(handler);
	}
	
	private class HandlerClass implements ActionListener 
	{

		@Override
		public void actionPerformed(ActionEvent event) 
		{
			JOptionPane.showMessageDialog(null, String.format("%s", event.getActionCommand()));
		}
		
		
	}
}

import javax.swing.JFrame;

public class ButtonTester
{
	public static void main(String[] args)
	{
		Gui go = new Gui();
		go.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
		go.setSize(300,200);
		go.setVisible(true);		
		
	}
	

}

You can do it two ways, either make a new listener for every button, or attach the same listener to all the buttons and check which button was pressed inside the actionPerformed. Take a look at the ActionEvent methods, I'm pretty sure the one you are using "getActionCommand()" gives you the name of the button that was clicked.
