Different types of operators in Java

java.Akarsh Sachan

Symbols that are used to perform a certain operation are known as operators. Examples: +,-,/,* etc.

Different types of operators available in Java are:

  • Arithmetic Operator
  • Assignment Operator
  • Logical Operator
  • Bitwise Operator
  • Relational Operator
  • Shift Operator
  • Unary Operator, and
  • Ternary Operator

Examples to understand different operators

Arithmetic Operator

class ArithmeticOperator {
 public static void main(String[] args) {
  int a = 15;
  int b = 5;
  System.out.println(a + b); //20
  System.out.println(a - b); //10
  System.out.println(a * b); //75
  System.out.println(a / b); //3
  System.out.println(a % b); //0
 }
}

class ArithmeticOperatorExpr {
 public static void main(String[] args) {
  System.out.println(10 * 10 / 5 + 3 - 1 * 4 / 2); //21
 }
}

Assignment Operator

class AssignmentOperator {
 public static void main(String[] args) {
  int a = 15;
  int b = 5;
  a += 4; //a=a+4
  b -= 4; //b=b-4
  System.out.println(a); //0
  System.out.println(b); //0
 }
}

class AssignmentOperator {
 public static void main(String[] args) {
  int a = 15;
  a += 4;
  System.out.println(a);
  a -= 4;
  System.out.println(a);
  a *= 2;
  System.out.println(a);
  a /= 2;
  System.out.println(a);
 }
}

class AssignmentOperator {
 public static void main(String[] args) {
  short a = 15;
  short b = 5;
  a = a + b; //Should throw Compile time error because 10+10=20 wiz int
  System.out.println(a);
 }
}

After type casting

class AssignmentOperator {
 public static void main(String[] args) {
  short a = 15;
  short b = 5;
  a = (short) a + b; //20 which is now converted to short
  System.out.println(a);
 }
}

Logical Operator

class LogicalOperator {
 public static void main(String[] args) {
  int a = 10;
  int b = 5;
  int c = 20;
  System.out.println(a < b && a++ < c); //false && true = false
  System.out.println(a); //10 because second condition is checked
  System.out.println(a > b || a++ < c); //true || true = true
  System.out.println(a); //10 because second condition is checked
 }
}

Bitwise Operator

class BitwiseOperator {
 public static void main(String[] args) {
  int a = 10;
  int b = 5;
  int c = 20;
  System.out.println(a < b & a++ < c); //false & true= false
  System.out.println(a); //11 because second condition is checked
  System.out.println(a > b | a++ < c); //true | true = true
  System.out.println(a); //12 because second condition is checked
 }
}

bitwise operator

Relational Operator

class RelationalOperator {
 public static void main(String[] args) {
  int a = 10;
  int b = 5;
  int c = 20;
  if (a >= b)
   System.out.println(a);
  If(b < c)
  System.out.println(b);
  If(a != c)
  System.out.println(c);
 }
}

Shift Operator

  • Left Shift: << operator is used to shift all bits in the value to the left, the specified number of times.
  • Right Shift: >> operator is used to shift all bits in the value to the right, the specified number of times.
class ShiftOperator {
 public static void main(String[] args) {
  System.out.println(10 << 2); //10*2^2=10*4=40
  System.out.println(10 << 3); //10*2^3=10*8=80
  System.out.println(20 << 2); //20*2^2=20*4=80
  System.out.println(15 << 4); //15*2^4=15*16=240
  System.out.println(10 >> 2); //10/2^2=10/4=2
  System.out.println(10 >> 3); //10/2^3=10/8=1
  System.out.println(20 >> 2); //20/2^2=20/4=5
  System.out.println(15 >> 4); //15/2^4=15/16=0
 }
}

Unary Operator

Uses:

  • Incrementing/decrementing a value by one
  • Negating an expression
  • Inverting the value of a boolean
class UnaryOperator {
 public static void main(String[] args) {
  int a = 10;
  int x = 10;
  int y = -10;
  boolean c = true;
  Boolean d = false;
  System.out.println(x++); //10(11)
  System.out.println(++x); //12
  System.out.println(x--); //12(11)
  System.out.println(--x); //10
  System.out.println(x++ + ++x); //10+12=22
  System.out.println(x++ + x++); //12+13=25
  System.out.println(~x); //-11 (minus of total positive value which starts from 0)
  System.out.println(~y); //9 (positive of total minus, positive starts from 0)
  System.out.println(!c); //false (opposite of Boolean value)
  System.out.println(!d); //true
 }
}

Ternary Operator

class TernaryOperator {
 public static void main(String[] args) {
  int a = 2;
  int b = 5;
  int min = (a < b) ? a : b;
  System.out.println(min);
 }
}
