Finding the intersection of two arrays [closed]

Answer 1

public static void main(String[] args) {
        int a[] = {3, 10, 4, 2, 8};
        int[] b = {10, 4, 12, 3, 23, 1, 8};
        int[] c = new int[(int)Math.min(a.length, b.length)];
        int i=0;
         for(int f=0;f

Hope it helps. Or if you have time complexity issue then try Java Set.
