问题 Could anyone explain to me in noob way what the difference is betweeen ImageIcon and Image classes/objects in Java? Thanks 回答1: Their nature and application is different.

How do I do that? also I made some images I want to display in the button backgrounds after the action is performed... 回答1: For the JButton, use this: JButton button = new JButton("Button Name", new ImageIcon("foo.png"); The Panel is a bit more interesting.
