I'm trying to get a specific value for a JButton in an array of JButtons, Here is part of my code:

In the ActionListener method i'm trying to set the text on a specific button a user clicks on to the changed text. I can't find anything in the Java API to help me, is there some other way to do this?

getSource should work. EventObject (Java Platform SE 7 )

the Object return will by getSource() the button that fired the action event. You'll need to cast the Object to JButton though and then call setText.

niiice. Thanks a ton!

Solution:

	@Override
	public void actionPerformed(ActionEvent e) {
		String buttonText = e.getActionCommand();
		JButton source = (JButton) e.getSource();
		if(buttonText.equals("-")){
			source.setText("Changed");
		}
	}
