Java duplicates in integer array [closed]

Answer 1

A solution, not the best in computation cycles but without memory overhead:

1. A loop to iterate the array A from 0 to N with index M
2. A nested loop to iterate A from M+1 to N with index S
3. if( A[M]=A[S] ) return true
4. return false (no duplicates found)

Answer 2

private boolean hasDuplicates(int []inArray)
{
    for(int i = 0; i < inArray.length - 1; i++)
        for(int j = i + 1; j < inArray.length; j++)
            if(inArray[i] == inArray[j])
                return true;
    return false;
}
