Arithmetic Operators Operator Description Example a = 10, b = 2, c = 0 + Addition c = a + b c = 10 + 2 c = 12 - Subtraction c = a - b c = 10 - 2 c = 8 * Multiplication c = a * b c = 10 * 2 c = 20 / Division c = a / b c = 10 / 2 c = 5 % Modulus c = a % b c = 10 % 2 c = 0 ++ Increment c = ++a c = 10 + 1 c = 11 -- Decrement c = --a c = 11 - 1 c = 10 Operator_Arithmetic.java public class Operator_Arithmetic { int a; int b; int c; Operator_Arithmetic() { a = 10; b = 2; } void add() { c = a + b; System.out.println("The Addition is : " + c); } void sub() { c = a - b; System.out.println("The Subtraction is : " + c); } void multi() { c = a * b; System.out.println("The Multiplication is : " + c); } void div() { c = a / b; System.out.println("The Division is : " + c); } void mod() { c = a % b; System.out.println("The Modulus is : " + c); } void inc() { c = ++a; System.out.println("The Increment is : " + c); } void dec() { c = --a; System.out.println("The Decrement is : " + c); } } class MainClass { public static void main (String args[]) { Operator_Arithmetic obj = new Operator_Arithmetic(); obj.add(); obj.sub(); obj.multi(); obj.div(); obj.mod(); obj.inc(); obj.dec(); } } Sample Output The Addition is : 12 The Subtraction is : 8 The Multiplication is : 20 The Division is : 5 The Modulus is : 0 The Increment is : 11 The Decrement is : 10 B. Relational Operators Operator Description Example == Check Equal a == 5 5 == 5 != Check Not Equal a != 5 6 != 5 > Check Greaterthan a > 5 10 > 5 < Check Lessthan a < 5 3 < 5 >= Check Greaterthan or Equal a >= 5 6 >= 5 <= Check Lessthan or Equal a <= 5 4 <= 5 Operator_Relation.java public class Operator_Relation { int a = 10; void relation() { if(a==10) { System.out.println("Equal Operator : Verified"); } if(a!=20) { System.out.println("Not Equal Operator : Verified"); } if(a>5) { System.out.println("Greaterthan Operator : Verified"); } if(a<15 span=""> System.out.println("Lessthan Operator : Verified"); } if(a>=9) { System.out.println("Greaterthan or Equal Operator : Verified"); } if(a<=11) { System.out.println("Lessthan or Equal Operator : Verified"); } } } class MainClass { public static void main (String args[]) { Operator_Relation obj = new Operator_Relation(); obj.relation(); } } Sample Output Equal Operator : Verified Not Equal Operator : Verified Greaterthan Operator : Verified Lessthan Operator : Verified Greaterthan or Equal Operator : Verified Lessthan or Equal Operator : Verified C. Bitwise Operators Operator Description Example ~ Unary bitwise complement ~ a & Bitwise AND a & b | Bitwise inclusive OR a | b ^ Bitwise exclusive OR a ^ b << Signed left shift a << b >> Signed right sift a >> b >>> Unsigned right shift a >>> b Operator_Bitwise.java public class Operator_Bitwise { public static void main(String args[]) { int a = 60; int b = 30; int c; System.out.println("Bitwise Operators"); c = ~a; System.out.println("\n~ a :" + c); c = a & b; System.out.println("\na & b : " + c); c = a | b; System.out.println("a | b : " + c); c = a ^ b; System.out.println("a ^ b : " + c); c = a << 2; System.out.println("\na << 2 : " + c); c = a >> 2; System.out.println("a >> 2 : " + c); c = a >>> 2; System.out.println("\na >>> 2 : " + c); } } Sample Output Bitwise Operators ~ a :-61 a & b : 28 a | b : 62 a ^ b : 34 a << 2 : 240 a >> 2 : 15 a >>> 2 : 15 D. Logical Operators Operator Description Example && Logical AND Operator a && b || Logical OR Operator a || b ! Logical NOT Operator !(a && b) Operator_Logical.java public class Operator_Logical { public static void main(String args[]) { boolean a = true; boolean b = false; boolean c; System.out.println("Logical Operators"); c = a && b; System.out.println("\na && b :" + c); c = a || b; System.out.println("a || b : " + c); c = !(a && b); System.out.println("\n!(a && b) : " + c); c = !(a || b); System.out.println("!(a || b) : " + c); } } Sample Output Logical Operators a && b :false a || b : true !(a && b) : true !(a || b) : false E. Assignment Operators Operator Example Equivalent Expression = z = x + y z = (x + y) += x += y x = (x + y) -= x -= y x = (x - y) *= x *= y x = (x * y) /= x /= y x = (x / y) %= x %= y x = (x % y) <<= x <<= y x = (x << y) >>= x >>= y x = (x >> y) &= x &= y x = (x & y) |= x |= y x = (x | y) ^= x ^= y x = x^y Operator_Assignment.java public class Operator_Assignment { public static void main(String args[]) {     int x = 10;     int y = 20;             System.out.println("Assignment Operators");         x += y;     System.out.println("\nThe addition is : " + x);     x -= y;     System.out.println("The subtraction is : " + x);     x *= y;     System.out.println("The multiplication is : " + x);     x /= y;     System.out.println("The division is : " + x);     x %= y;     System.out.println("The remainder is : " + x);     x &= y;     System.out.println("The result of AND operation : " + x);     x |= y;     System.out.println("The result of Bitwise inclusive OR operation : " + x);     x <<= y;     System.out.println("The result of Signed left shift operation : " + x); } } Sample Output Assignment Operators The addition is : 30 The subtraction is : 10 The multiplication is : 200 The division is : 10 The remainder is : 10 The result of AND operation : 0 The result of Bitwise inclusive OR operation : 20 The result of Signed left shift operation : 20971520 F. Conditional Operator Operator_Conditional.java public class Operator_Conditional { public static void main(String args[]) { int a = 10 , b; System.out.println("Conditional Operators"); b = (a == 1) ? 100 : 200; System.out.println( "\nValue of b is : " +  b ); b = (a == 10) ? 100 : 200; System.out.println( "Value of b is : " + b ); } } Sample Output Conditional Operators Value of b is : 200 Value of b is : 100
