Equality with References to Objects:

Two different logical tests available:

1. The operator = = (equality)

• It evaluates whether two references point  to the same object.

2. The method equals( )

• It evaluates whether the internal state

(i.e., contents) of one object is identical

to the internal state of another object.

• It is a special method built-in to the

class Object, and is available to all

classes you create. In practice you

will want to code a version of equals()

in your classes, so that you can

compare objects.
