              4.3.3 Logical Operators
              Logical operators are used to check whether an expression is true or false. The output of the logical operators is
              the outcome of different conditions as "true" or "false" depending on the relationship between the expressions.
              There are three types of logical operators in Java. They are && (AND), || (OR) and ! (NOT). Let us learn about them
              in detail.


              The && Operator
              The (&&) operator is known as the "Logical AND" operator. It is used for merging two conditions to make an expression.
              If both the conditions in an expression satisfy, then the outcome of the && operator is true, otherwise false if any one
              of the conditions does not satisfy. In Java programming, 0 (zero) denotes the false value and 1 (one) denotes the true
              value. For example, if we take an expression (a>b && b>c), then the output will be:

                                Condition 1               Condition 2           Condition 1 && Condition 2
                                   (a>b)                     (b>c)                    (a>b && b>c)
                                 0 / false                 0 / false                     0 / false
                                 0 / false                  1 / true                     0 / false
                                  1 / true                 0 / false                     0 / false
                                  1 / true                  1 / true                     1 /  true

              The || Operator
              The (||) operator  is known as the  "Logical  OR"  operator. It  is also  used for  merging two conditions  to make  an
              expression.  If any one of the conditions  in  the expression  satisfies, then the outcome is true  otherwise false.
