Relational operator
---------------------------------
Relational Operators in Java are used to comparing two variables for equality, non-equality, greater than, less than, etc. Java relational operator always returns a boolean value – true or false.

Following are the type of Relational Operators:

1.Less Than operator
2.Greater Than operator
3.Less Than Equal to operator
4.Less Than Equal to operator
5.Equal to operator
6.Not Equal to operator

Logical operator
--------------------------------------
These operators are used to perform logical “AND”, “OR” and “NOT” operation, i.e. the function similar to AND gate and OR gate in digital electronics.

Following are the type of Logical operator :
1.AND Logical operator
2.OR Logical operator
3.NOT Logical operator

AND Logical Operator:
------------------------------------
This operator returns true when both the conditions under consideration are satisfied or are true. If even one of the two yields false, the operator results false. For example, cond1 && cond2 returns true when both cond1 and cond2 are true (i.e. non-zero).

OR Logical Operator :
----------------------------------
This operator returns true when one of the two conditions under consideration is satisfied or is true. If even one of the two yields true, the operator results true. To make the result false, both the constraints need to return false.

NOT Logical Operator:
-------------------------------------
Unlike the previous two, this is a unary operator and returns true when the condition under consideration is not satisfied or is a false condition. Basically, if the condition is false, the operation returns true and when the condition is true, the operation returns false.
