[Anand]

private static void findCommonElements(int[] arr1,
int[] arr2)
{

// Check if length of arr1 is greater than 0
// and length of arr2 is greater than 0
if (arr1.length > 0 && arr2.length > 0) {
Set<Integer> firstSet = new HashSet<Integer>();
for (int i = 0; i < arr1.length; i++) {
firstSet.add(arr1[i]);
}

// Iterate the elements of the arr2
for (int j = 0; j < arr2.length; j++) {
if (firstSet.contains(arr2[j])) {
System.out.println(arr2[j]);
}
}
}
}
