JAVA PROGRAM HELP

I need someone to edit this program to do the following remaining things:

- I need the chaser to run on a timed interval. That is, I basically need it to chase the runner on its own, every 300 timesteps, instead of what it is doing now (making its turn only when the runner presses a key)

- I need the program to also stop running at x amount of seconds and pop up a window saying "You Won!" if the chaser never reached the runner for x amount of time

If you need more information for what I need, the instructions are found here: http://www.cs.utsa.edu/~cs1063/projects/index.html (Project 2: Survivor I)

Here if my code so far:
