That's all on this list of Java interview Questions on Equals and HashCode methods in Java. It's one of the fundamental concepts of Java programming language, but YET has several subtle things, which is unknown to many Java programmers. I strongly suggest to GET yourself really good on equals(), hashCode(), compareTo() and compare() method, not only to do well on Java Interviews but also to write correct CODE in Java.
