Hey, What's up y'all,

I am trying to write some code in Java that will read in the numbers from a file (one # on each line of .txt file) put them into an array, and then run quick sort on the array. Eclipse is showing some red that I am having trouble with. My errors are marked with comments, and what the error is, if anyone can help me get this to run, thanks everyone!
