I am trying to have this quiz like game where user have 3 buttons to choose from. If they chose the wrong answer, an image bomb wil appear and immediately it wil automatically change to the next question and if they chose the corect one, it will also change to the next question. However, my problem here is that i do not know if i wrote my if...else statements correctly. When i run my program, it doesn't change to the next question and there is no bomb image appearing too. I tried many methods to solve this but i stil could'nt. I really need help.
Here is my code and the if... else statements is from line 244 to 388.

Answer 1

This code is way too long to go through it, but a quick look at your if statements reveals you are checking whether a JButton is selected. What you probably want is adding an ActionListener to the JButton, which will be called when the user clicks the JButton. In the ActionListener you can then check whether the correct answer was given and proceed, or show the 'bomb image'.
I suggest you take a look at the Swing button tutorial and more specifically the JButton part of the tutorial
