Answer 2

Why not just concatenate the two arrays (String ClassOne and ClassTwo) into one and then call a MergeSort on one array? Your process makes the program more ambiguous in my opinion.

Answer 3

Just change this:

if (names.length > 2)

to

if (names.length > 1)

mergeSort runs recursively spliting the array into two halves, then merges them and return back up the call chain. When the length of the array passed to mergeSort is <= 1 it considers the array sorted, this is called the base case.
