I am making a typing app for a school project, I am trying to implement the KeyListener class however, when I look at any of the methods like “keyTyped”, there is a message saying throws UnsupportedOperationException.If I code anything underneath it it highlights that code as an unreachable statement. I’ve tried deleting the message and coding as normal, however, this only leads to the method never working when you type a key on the frame.
I originally ignored the exception and coded above it but it just produces nothing in the return box.
I also am not sure how to add the key listener, this could be part of the problem.
here is my code:
the main issue is at the bottom.
