Reading in text file and comparing records

[Craig]

1) How do I read in a text file into Java? i.e. one line at a time and store
each line in an array?

2) If I have two arrays, one large and a smaller one containing a selection
of the elements in the large array, how do I perform a comparison of the two
arrays which finds any elements in the large array which are missing from
the small array?
