Trouble with 'if statements' inside other 'if statements'

if(clicked == button) {
    button.setIcon(image1);
    if(clicked == button2) {
        button2.setIcon(image2)
        button1.setIcon(image0)
     }
}

Basically what I want the code to do, is upon clicking 'button' it's image will be set to 'image1' and after that happens(specifically not before) if another button is clicked it will set that button(button2) to 'image2' and make the first button display 'image0' it's "idle" image, if you will. Now if all of this makes sense, I'd like to get an answer of why clicking 'button2' after clicking 'button' doesn't do anything PS. YES, I have the action listeners, and everything setup for the JLabels etc, all I need help on is getting the if statement inside of the other if statement to be 'run' after the first if statement, and only if the first 'button' is clicked.
