Java Multiply Function Explained

In Java, the multiply function is commonly used to calculate the product of two numbers. It can be a custom function or a built-in method, depending on how it’s implemented in the code.

Function customExample:

public static int multiply(int num1, int num2) {
    return num1 * num2;
}

public static void main(String[] args) {
    int result = multiply(5, 10);
    System.out.println("Result: " + result); // Output: Result: 50
}

Examples of built-in methods:

public static void main(String[] args) {
    int num1 = 5;
    int num2 = 10;
    int result = Math.multiplyExact(num1, num2);
    System.out.println("Result: " + result); // Output: Result: 50
}

It is important to note that the Math.multiplyExact() method will check if the product exceeds the int range and throw an exception if it does.
