4.1 Arithmetic Operators:

In Java, arithmetic operators allow you to perform mathematical operations. Here are some common arithmetic operators:

• + Addition: Adds two values together.
• `` Subtraction: Subtracts one value from another.
• `` Multiplication: Multiplies two values.
• / Division: Divides one value by another.
• % Modulus: Returns the remainder of a division.

Let's look at an example that demonstrates the usage of arithmetic operators:

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

        int sum = a + b;            // Sum: 14
        int difference = a - b;     // Difference: 6
        int product = a * b;        // Product: 40
        int quotient = a / b;       // Quotient: 2
        int remainder = a % b;      // Remainder: 2

        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);
    }
}

• In this example, we perform various arithmetic operations using the values of a and b and store the results in separate variables.
• We then print the values of these variables.

4.2 Assignment Operators:

• Assignment operators are used to assign values to variables. The most common assignment operator is =
• Here's an example:

public class AssignmentOperators{
    public static void main(String[] args) {
        int x = 5;
        int y = 10;

        x += 3;     // Equivalent to x = x + 3 -> x: 8
        y *= 2;     // Equivalent to y = y * 2 -> y: 20

        System.out.println("x: " + x);
        System.out.println("y: " + y);
    }
}
