What are Arithmetic Operators?

Arithmetic operators are symbols that represent mathematical operations such as addition, subtraction, multiplication, division, and modulus. These operators are used to manipulate numerical data and perform calculations.

Types of Arithmetic Operators in Java

Java provides several arithmetic operators:

1. Addition (+)
2. Subtraction (-)
3. Multiplication (*)
4. Division (/)
5. Modulus (%)
6. Increment (++)
7. Decrement (--)

1. Addition (+)

The addition operator adds two operands.

Example:

public class AdditionExample {
    public static void main(String[] args) {
        int a = 10;
        int b = 5;
        int result = a + b;
        System.out.println("Addition: " + result); // Output: Addition: 15
    }
}

2. Subtraction (-)

The subtraction operator subtracts the second operand from the first operand.

Example:

public class SubtractionExample {
    public static void main(String[] args) {
        int a = 10;
        int b = 5;
        int result = a - b;
        System.out.println("Subtraction: " + result); // Output: Subtraction: 5
    }
}

3. Multiplication (*)

The multiplication operator multiplies two operands.

Example:

public class MultiplicationExample {
    public static void main(String[] args) {
        int a = 10;
        int b = 5;
        int result = a * b;
        System.out.println("Multiplication: " + result); // Output: Multiplication: 50
    }
}

4. Division (/)

The division operator divides the first operand by the second operand. It is important to note that when using integer division, the result is an integer.

Example:

public class DivisionExample {
    public static void main(String[] args) {
        int a = 10;
        int b = 5;
        int result = a / b;
        System.out.println("Division: " + result); // Output: Division: 2
    }
}

5. Modulus (%)

The modulus operator returns the remainder when the first operand is divided by the second operand.

Example:

public class ModulusExample {
    public static void main(String[] args) {
        int a = 10;
        int b = 3;
        int result = a % b;
        System.out.println("Modulus: " + result); // Output: Modulus: 1
    }
}

6. Increment (++)

The increment operator increases the value of the operand by 1. It can be used as a prefix or postfix operator.

Example:

public class IncrementExample {
    public static void main(String[] args) {
        int a = 10;
        a++;
        System.out.println("Increment: " + a); // Output: Increment: 11
    }
}

7. Decrement (--)

The decrement operator decreases the value of the operand by 1. It can be used as a prefix or postfix operator.

Example:

public class DecrementExample {
    public static void main(String[] args) {
        int a = 10;
        a--;
        System.out.println("Decrement: " + a); // Output: Decrement: 9
    }
}

Conclusion

Arithmetic operators in Java are fundamental for performing basic mathematical operations. Understanding and using these operators correctly is crucial for effective programming and data manipulation. They provide a foundation for more complex mathematical computations and algorithms in Java applications.
