Question

I need to write a program for someone to enter 5 numbers from 10 to 100 but I don’t know how i can eliminate duplicates? Anybody got any bright ideas on how i can do it?

Answer 1

Use a Set implementation whic by definition does not contain duplicates…

TreeSet<Integer> ints = new TreeSet<Integer>();

int[] int_array = { 1, 2, 3, 4, 3, 5, 4, 2, 3, 4, 3 4, 2, 1 };

for (int n : int_arr)
   ints.add(n);

for (int n : ints)
  System.out.preintln(n);

outputs:
1
2
3
4
5
