What are the common arithmetic operators in Java?

Common Arithmetic Operators in Java

In Java, the common arithmetic operators are used to perform basic mathematical operations on numeric data types. These operators allow you to add, subtract, multiply, divide, and perform other mathematical calculations on your data. Here are the common arithmetic operators in Java:

1. Addition (+): The addition operator is used to add two operands together. For example, int result = 5 + 3; would result in result being assigned the value 8.

2. Subtraction (-): The subtraction operator is used to subtract the right operand from the left operand. For example, int result = 10 - 4; would result in result being assigned the value 6.

3. Multiplication (*): The multiplication operator is used to multiply two operands. For example, int result = 7 * 3; would result in result being assigned the value 21.

4. Division (/): The division operator is used to divide the left operand by the right operand. For example, int result = 15 / 3; would result in result being assigned the value 5.

5. Modulus (%): The modulus operator is used to find the remainder of a division operation. For example, int result = 17 % 5; would result in result being assigned the value 2, as 17 divided by 5 has a remainder of 2.

6. Increment (++): The increment operator is used to increase the value of a variable by 1. For example, int x = 5; x++; would result in x being assigned the value 6.

7. Decrement (--): The decrement operator is used to decrease the value of a variable by 1. For example, int x = 5; x--; would result in x being assigned the value 4.

These arithmetic operators can be used in various expressions and statements to perform calculations and manipulate numeric data in your Java programs. It's important to understand the order of operations (PEMDAS: Parentheses, Exponents, Multiplication, Division, Addition, Subtraction) when using multiple operators in a single expression.

Here's a simple example that demonstrates the use of some of these arithmetic operators:

public class ArithmeticOperators {
    public static void main(String[] args) {
        int a = 10;
        int b = 4;

        int sum = a + b;
        int difference = a - b;
        int product = a * b;
        int quotient = a / b;
        int remainder = a % b;

        System.out.println("Sum: " + sum);
        System.out.println("Difference: " + difference);
        System.out.println("Product: " + product);
        System.out.println("Quotient: " + quotient);
        System.out.println("Remainder: " + remainder);
    }
}

This code will output:

Sum: 14
Difference: 6
Product: 40
Quotient: 2
Remainder: 2

In this example, we demonstrate the use of the addition, subtraction, multiplication, division, and modulus operators to perform various arithmetic calculations.
