                        class OperatorExample {
                               public static void main(String[]args) {

                        int a = 10;
                        int b= -10
                        boolean c= true;
                        boolean d = false;

                        System.out.println(~a);      // -11 (minus of total positive value which starts from 0)
                        System.out.println(~b);      // 9 (positive of total minus positive starts from 0)
                        System.out.println(!c);      // false (opposite of Boolean value)
                        System.out.println(!d)       // true
                        } }


               Java Arithmetic Operators
                       Java  arithmetic  operators  are  used  to  perform  addition,  subtraction,  multiplication,
               division and getting the remainder. They act as basic mathematical operations.

                              class OperatorExample {
                                     public static void main(String[]args) {

                              int a=10, b=5;
                              System.out.println( a+b );          Output:
                              System.out.println( a-b );          15

                              System.out.println( a*b );          5
                              System.out.println( a/b );          50

                              System.out.println( a%b );          2
                              } }                                 0


               Java Assignment Operators
                       Assignment Operator is used to perform a specific operation and then assigning the
               result as the new value of the variable.
                          Operator                     Operation                    Equivalent to
                             +=                          A += B                       A = A + B
                             -=                          A -= B                       A = A – B
                             *=                          A *= B                       A = A * B
                             /=                          A /= B                       A = A / B
                             %=                          A %= B                      A = A % B
               Example:

                  class OperatorExample {
                        public static void main(String[]args) {

                  int a=10, b=5;
                  System.out.println( a += b );   // ( new value of a is 15)
                  System.out.println( a -= b );   // (new value of a is 5)
                  System.out.println( a *=b );   // (new value of a is 50)
                  System.out.println( a /= b );   // (new value of a is 0)
                  System.out.println( a %= b );   // (new value of a is 0)
                  } }
