How to group?

Kind of a vague question, but didn't know how to ask it. Basically I have a this set of code, I posted the first 2 of 6, and I wanted to know how I would be able to reduce this into 1?

basically the code is EXACTLY the same besides f1,f2,f3,....,f6.

I figured I might be able to do something like f(n) or something like that, but I don't know.

Instead of having six variables f1, f2, f3, ..., f6 you could create an array.

Have a look at: The Java Tutorials - Arrays.

For example:

Access the six elements of the array as f[0], f[1], f[2], ..., f[5]. Ofcourse you can use a variable to index into the array:
