Really simple program, for a newbie.

ram130 (4)
hey, I'm trying to create a program that will prompt the user for 3 options and depending on the selection one out of the 3 codes excutes. Each his a draw or eclipse type. I'm fairly new to programming so any help will be appreciated.

My road block is at the prompting the users and some errors here and there. Here is what I have so far, not sure how to proceed. This was done in the processing app:

What are the errors? And could you point out where in the code you're having trouble?
ram130 (4)
It's complaining about more than one setup so I'm trying to remove that. Each code was created in a separate session so I am trying to combine them into one and give the user a option between each to select .. Something like " What would you like to see? 1, 2 or 3? _ _ "

ram130 (4)
ok updated code..now just getting some overflow errors, how do I go about letting the user choose between each code?

Anyone? I just want to turn all these codes into a KeyPressed action now so if a user pressed 1, it goes to code 1 and executes and so on...anyone? :/
