equals() method is from Object Class.So this is the method
to check the equality between two objects.This method
implements the equalence relation.

ex obj1 o1 = "ravi";
obj2 o2 = "ravi";

o1.equals(o2) ;// returns true.

== Operator. no doubt this is the operator. It can be used
in two ways
1:To compare the values of primitive variables.
2.To compare the object refference variables.
it returns true if refference variable reffering to the
same object.

ex obj1 a
obj2 b
obj1 c

a==c----> returns true.
a==b----> returns false.
