Arithmetic Operators in Java

Arithmetic operators in Java are used to perform basic mathematical operations such as addition, subtraction, multiplication, division, and finding the remainder. These operators work with numeric data types like int, float, double, and long.

In this tutorial, you will learn about different types of arithmetic operators in Java with syntax, examples, and practical explanations.

What are Arithmetic Operators in Java?

Arithmetic operators are special symbols used to perform mathematical calculations between two or more values. Java provides several arithmetic operators that help developers perform numerical operations easily.

For example, the + operator is used to add two numbers, while the - operator is used to subtract one number from another.

Types of Arithmetic Operators in Java

Java provides the following arithmetic operators:

Basic Example of Arithmetic Operators in Java

public class Main {

    public static void main(String[] args) {
        int a =20;
        int b =10;
        int sum = a + b; 
        int difference = a - b; 
        int multiply = a * b; 
        int divide = a / b; 
        int remainder = a % b; 
        System.out.println(sum);
        System.out.println(difference);
        System.out.println(multiply);
        System.out.println(divide);
        System.out.println(remainder);
    }
}

Addition Operator (+) in Java

The addition operator (+) is used to add two or more numeric values. It combines the values and returns their total result.

int number1 =  15;
int number2 = 25;
int result = number1 + number2;
System.out.println(result);

40

Subtraction Operator (-) in Java

The subtraction operator (-) is used to subtract one value from another value.

int total =  50;
int used =  20;
int remaining = total - used; 
System.out.println(remaining);

30

Multiplication Operator (*) in Java

The multiplication operator (*) is used to multiply two or more numeric values.

int price = 100;
int quantity =  5;
int total = price * quantity; 
System.out.println(total);

500

Division Operator (/) in Java

The division operator (/) is used to divide one number by another number and returns the quotient.

int number1 =  100;
int number2 =  10;
int result = number1 / number2; 
System.out.println(result);

10

Modulus Operator (%) in Java

The modulus operator (%) returns the remainder after dividing one number by another number.

int number1 =  17;
int number2 =  5;
int result = number1 % number2; 
System.out.println(result);

2

Increment and Decrement Operators in Java

Java also provides increment (++) and decrement (--) operators to increase or decrease the value of a variable by 1.

int value =  10 value++;
System.out.println(value);
value--;
System.out.println(value);

Rules for Using Arithmetic Operators in Java

While using arithmetic operators in Java, some important rules should be followed to avoid unexpected results.

Arithmetic Operators Precedence in Java

When multiple arithmetic operators are used in a single expression, Java follows a specific order called operator precedence.

Example of Arithmetic Operator Precedence

int result =  10 +  5 * 2;
System.out.println(result);
