I'm using netbeans btw if you notice the long code for the GUI
I'm doing a quiz game. The questions are randomized.
My problem is, the randomized questions do not appear on the questionLabel (JLabel Variable). I don't know what to do.
Help?

I can't comment on yur code becuase I don't have the actual version you are running, so it's time for you to do some debugging...
Add print statements to your code so you can see what is being executed and what is not. Eg one at the start of questionrandomiser, one inside each of its if blocks etc.

Edited 1 Year Ago by JamesCherrill

it printed all the elements inside the array. i just want one random element to be printed

my mistake. it was just one. i thought it was all elements because i used a mouseEntered event
