    It prints out the string variables (which is fine), but then it gives me these compiler errors. Mind you, that's when I use the second line of code (which I currently have as a comment).

    Re: Java Program: Falling Distance Problem

    I was able to get the value of seconds to change (e.g. 1, 2, 3, 4, 5...10). How do I get the value to change for meters is the question I'm asking.

    Re: Java Program: Falling Distance Problem

    All I had to do was include "=" to if(fallingTime > 1).

    Thanks for the reply.

    I just typcasted the double into int (seems to work).

    Re: Help with Java Program!

    It is, right? The program does ask for the service package first, then the number of hours used..Or is the program written in the wrong order in terms of execution of the statements?

    Re: Help with Java Program!

    Whoops, my bad. It's under "Default." Towards the end of the program.
