Ok, this is my code. Now what I want the program to accomplish is for the program to display the blank screen(which I have done) then when the user clicks one of the buttons and it places a X on that button. Then after 6 clicks for the program to translate the pattern they put in to the input array, so I can compare the input array to the pattern array, and be able to tell the user if its correct or not and move on. What this program does now is it displays the blank screen then when a button is pressed it displays the X. I got it to check for one button but I don't know how to check for all of them. So how could I check each button for the text it holds.

Answer 1

You can call getComponents() on the parent container- whether panel, frame or window and then check if it is an instance of button, then check the text set on it like this:

Component[] comps = parent.getComponents();
for(Component c:comps){
    if(c instanceof JButton){
        JButton btn = (JButton) c;
        String text = btn.getText();
        //Use text for whatever, add it to an array or something
    }
}

Hope you get the idea
