Arithmetic Operators in Java

Java Arithmetic Operators in provides the ability to perform Mathematical Arithmetic operations in Java programming.

The following are the list of Arithmetic Operations supported in Java.

  • Addition
  • Subtraction
  • Multiplication
  • Division
  • Modulus
  • Increment (Pre-Increment, Post-Increment)
  • Decrement (Pre-Decrement, Post-Decrement)

Arithmetic Operators that require two operands

Out of the seven arithmetic operators, that java provides, the operators mentioned in the below table require two operands to perform the arithmetic operation.

ArithmeticOperationOperatorSymbolExampleDescription
Addition + a + bReturns sum of a and b.
Subtraction - a – bReturns difference of b from a.
Multiplication * a * bReturns product of a and b.
Division / a / bReturns the quotient when a is divided by b.
Modular Division % a % bReturns reminder when a is divided by b.
Increment ++ a++ is Post-Increment.++a is Pre-Increment.Increments the value of a by one.Post-Increment: The value of a is updated, only after the execution moves to next statement.Pre-Increment: The value of a is updated during the execution of this statement itself.
Decrement -- a-- is Post-Decrement.--a is Pre-Decrement.Decrements the value of a by one.Post-Decrement: The value of a is updated, only after the execution moves to next statement.Pre-Decrement: The value of a is updated during the execution of this statement itself.

Example

Now, let us see the demonstration of arithmetic operators with an Example Java Program, ArithmeticOperatorsExample.java.

Main.java

public class Main {
	public static void main(String[] args) {
		int a = 10;
        int b = 5;

		System.out.println("Addition :       (a + b) = " + (a + b));
		System.out.println("Subtraction :    (a - b) = " + (a - b));
		System.out.println("Multiplication : (a * b) = " + (a * b));
		System.out.println("Division :       (a / b) = " + (a / b));
		System.out.println("Modulus :        (a % b) = " + (a % b));
        a = 10;
		System.out.println("During Post-Increment :   a = "+(a++));
        System.out.println("After  Post-Increment :   a = " + a);
        a = 10;
		System.out.println("During Pre-Increment :    a = " + (++a));
        System.out.println("After  Pre-Increment :    a = " + a);
		a = 10;
		System.out.println("During Post-Decrement :   a = "+(a--));
        System.out.println("After  Post-Decrement :   a = " + a);
        a = 10;
		System.out.println("During Pre-Decrement :    a = " + (--a));
        System.out.println("After  Pre-Decrement :    a = " + a);
	}
}

Output

ddition :       (a + b) = 15
Subtraction :    (a - b) = 5
Multiplication : (a * b) = 50
Division :       (a / b) = 2
Modulus :        (a % b) = 0
During Post-Increment :   a = 10
After  Post-Increment :   a = 11
During Pre-Increment :    a = 11
After  Pre-Increment :    a = 11
During Post-Decrement :   a = 10
After  Post-Decrement :   a = 9
During Pre-Decrement :    a = 9
After  Pre-Decrement :    a = 9
