Printing distinct integers in an array

Question

I\'m trying to write a small program that prints out distinct numbers in an array. For example if a user enters 1,1,3,5,7,4,3 the program will only print out 1,3,5,7,4.

Answer 1

Try throwing all of the integers into a Set. Duplicates will not ever be added to the Set and you will be left will a set of unique integers.
