Comparing elements of an array

**fluteattack** · 05-09-2011, 05:35 PM

We are to code two sets of integers (equal sizes) and find the union, intersect, and complement of the two sets.

I can't find anything in our text that deals with comparing elements of an array and displaying the results. I'm very new to working with arrays (very new to Java in fact). Where should I start with this problem?

Thanks for your help.

If 'a' is an array of ints then a[j] is an int (the j-th element of the array); j can be any other int used as an index in the array. Do you really have to work with arrays? Arrays are so 1960s Fortanesque ... have a look at ArrayLists or even Sets.

kind regards,
