1. Arithmetic Operators Example

public class Arithmetic {
      public static void main(String args[]) {
            int a = 10;
            int b = 20;
            int c = 25;
            int d = 25;
            System.out.println("a + b = " + (a + b) );
            System.out.println("a - b = " + (a - b) );
            System.out.println("a * b = " + (a * b) );
            System.out.println("b / a = " + (b / a) );
            System.out.println("b % a = " + (b % a) );
            System.out.println("c % a = " + (c % a) );
            System.out.println("a++ = " + (a++) );
            System.out.println("b-- = " + (a--) );
            // Check the difference in d++ and ++d
            System.out.println("d++ = " + (d++) );
            System.out.println("++d = " + (++d) );
      }
}

Output :

a + b = 30, a - b = -10, a * b = 200, b / a = 2, b % a = 0, c % a = 5, a++ = 10, b-- = 11, d++ = 25, ++d = 27

2. Relational Operators Example

public class Relational {
      public static void main(String args[])
            int a = 10;
            int b = 20;
            System.out.println("a == b = " + (a == b) );
            System.out.println("a != b = " + (a != b) );
            System.out.println("a > b = " + (a > b) );
            System.out.println("a < b = " + (a < b) );
            System.out.println("b >= a = " + (b >= a) );
            System.out.println("b <= a = " + (b <= a) );
      }
}

Output :

a == b = false, a != b = true, a > b = false, a < b = true, b >= a = true, b <= a = false

3. BitWise Operators Example

public class BitWise {
      public static void main(String args[]) {
            int a = 60;
            int b = 13;
            int c = 0;
            c = a & b;
            System.out.println("a & b = " + c );
            c = a | b;
            System.out.println("a | b = " + c );
            c = a ^ b;
            System.out.println("a ^ b = " + c );
            c = ~a;
            System.out.println("~a = " + c );
            c = a << 2;
            System.out.println("a << 2 = " + c );
            c = a >> 2;
            System.out.println("a >> 2 = " + c );
            c = a >>> 2;
            System.out.println("a >>> 2 = " + c );
      }
}

Output :

a & b = 12, a | b = 61, a ^ b = 49, ~a = -61, a << 2 = 240, a >> 15, a >>> 15

4. Logical Operators Example

public class Logical {
      public static void main(String args[]) {
            boolean a = true;
            boolean b = false;
            System.out.println("a && b = " + (a&&b));
            System.out.println("a || b = " + (a||b) );
            System.out.println("!(a && b) = " + !(a && b));
      }
}

Output :

a && b = false, a || b = true, !(a && b) = true

5. Assignment Operators Example

public class Assignment {
      public static void main(String args[]) {
            int a = 10;
            int b = 20;
            int c = 0;
            c = a + b;
            System.out.println("c = a + b = " + c );
            c += a;
            System.out.println("c += a = " + c );
            c -= a;
            System.out.println("c -= a = " + c );
            c *= a;
            System.out.println("c *= a = " + c );
            a = 10;
            c = 15;
            c /= a;
            System.out.println("c /= a = " + c );
            a = 10;
            c = 15;
            c %= a;
            System.out.println("c %= a = " + c );
            c <<= 2;
            System.out.println("c <<= 2 = " + c );
            c >>= 2;
            System.out.println("c >>= 2 = " + c );
            c >>= 2;
            System.out.println("c >>= a = " + c );
            c &= a;
            System.out.println("c &= 2 = " + c );
            c ^= a;
            System.out.println("c ^= a = " + c );
            c |= a;
            System.out.println("c |= a = " + c );
      }
}

Output :

c = a + b = 30, c += a = 40, c -= a = 30, c *= a = 300, c /= a = 1
c %= a = 5, c <<= 2 = 20, c >>= 2 = 5, c >>= 2 = 1, c &= a = 0, c ^= a = 10, c |= a = 10

6. Conditional Operators Example

public class Conditional {
      public static void main(String args[]){
            int a, b;
            a = 10;
            b = (a == 1) ? 20: 30;
            System.out.println( "Value of b is : " + b );
            b = (a == 10) ? 20: 30;
            System.out.println( "Value of b is : " + b );
      }
}

Output :

Value of b is : 30, Value of b is : 20
