When comparing Object arrays, null elements are equal If the elements are not null, Object equals() is used

import java.util.Arrays; public class Main {   public static void main(String[] argv) throws Exception {     boolean b = Arrays.equals(new String[] { "a" }, new String[] { "a" });     b = Arrays.equals(new String[] { null }, new String[] { null });      b = Arrays.equals(new String[] { "a" }, new String[] { null });    } }
