Cleaning up

[DGates]

Hi,
This is sort of related to an earlier post that I made.
The only way I could think of using an array in multiple places in my program was to repeat code. I was lead to believe this is bad practice however.
If you look below you can see what I have done.
Does anyone know of a way to reduce this code re-usage?
Any help is appreciated,
Thanks,
Dan

What is this code snippet supposed to be doing?

[DGates]

It reads a tab delimited file, and stores the information in arrays. It works fine.
The System.out functions are just testing it's output they are sort of irrelevant.
