Question

I have a hundred buttons called

JButton btnHelp1, btnHelp2, … btnHelp100;

I want to go from string to a jbutton name for another method to set the foreground like so

    for(x = 1; x < 101; x++){ 
        String buttonName = "btnHelp" + x;
        // convert by doing something like...
        JButton a = buttonName;
        a.setForeground(Color.yellow);
    }

Answer 1

What you are describing isn’t possible. However, you can add all of your buttons in a List, and go through every elements (buttons) of your list and change its background.

for (JButton button: myButtonsList) {
    button.setBackground (Color.Yellow)
}
