Question: I have two String arrays: array A and array B. Now I want to get the elements of array A that are not present in array B and vice versa. Can I do that without loop?

Answer: You can do that with java.util.AbstractSet class.

AbstractSet setA = new AbstractSet();
setA.addAll(Arrays.asList(arrayA));
AbstractSet setB = new AbstractSet();
setB.addAll(Arrays.asList(arrayB));
setA.removeAll(setB);
String[] cleanedA = setA.toArray(new String[] {});
