Need help starting a program.

I have to write a program that reads in a file of male and female GPAs, then gives me the avergae male gpa and average female gpa.

The text in the file will look like this:

f3.9
m4.0
f2.5
m3.4

Where the first character represents male or female and the number represents the gpa obviously. Can anyone point me in the right direction on how to start this?

You can read each line of the file and get the String's first index using string.charAt(int index).

If you are unsure how to read files here is an example: Java Read File Line By Line,How to Read File Line By Line in Java

Thanks, I'll give that a go.
