                     5.2 FORMS OF OPERATORS
                 In Java, there are mainly three forms of operators. Let us learn one by one in detail.


                                                         FORMS OF OPERATOR





                                         UNARY                  BINARY                TERNARY



                 5.2.1 Unary Operator
                 An operator that works with only one operand is called unary operator. For example, a++, --b.

                 Where, a and b are the operands, ++ and -- are the unary operators.
