Hi,
I have two arrays of integers. i need to compare each element of one
array with each element of another array.
say..one master list, from 1 to 100 in one array.
and another list, from 20 to 40 in another array.
After comparision of two arrays, it should return a another arraylist
which should contain only 1 to 19 and 41 to 100.

how to do this?
Thanks for your inputs.

If you are having trouble knowing 'where to begin',
check Patricia Shanahan's advice at..

Note that a better group for those starting in Java is
'comp.lang.java.help'.

I should have used some java "techie" terms here...
any how, i got the solution..
I created two sets of data. and used following method:
set1.removeAll(set2)..
removeAll method removes from set1 all of its elements that are
contained in the specified collection (here set2)...
