## Overview

**`multiplyFull`** is a static method in the `Math` class in Java. It is used to return the exact mathematical product of two integer numbers. 

This method was introduced in `Java 9`. Hence, it's important to use `Java 9` and above versions to use this function.

The `multiplyFull` method is defined in the `Math` class. The `Math` class is defined in the `java.lang` package. 

To import the `Math` class, check the following import statement.

```
import java.lang.Math;
```

#   
## Method signature

```
public static long multiplyFull(int x, int y)
```
## Parameters

`int x`: the first integer value to be multiplied.  
`int y`: the second integer value to be multiplied.

## Return value:  
This method returns the product as `long` datatype.

#   
## Examples

In the code below, we define two integers and a `long` result variable to hold the result of the product.


import java.lang.Math;

public class Main {

    public static void main(String[] args) {
        int firstValue = 12345678;
        int secondValue = 987654321;
        long result = Math.multiplyFull(firstValue, secondValue);
        System.out.println("Result - " + result);

    }
}

In the code below, we use the maximum value and minimum value an integer datatype can hold as the values to be multiplied.

import java.lang.Math;

public class Main {

    public static void main(String[] args) {

        int firstValue = Integer.MAX_VALUE;
        int secondValue = Integer.MIN_VALUE;
        long result = Math.multiplyFull(firstValue, secondValue);
        System.out.println("Result - " + result);

    }
}

What is Math.multiplyFull in Java?

`Math.multiplyFull` in Java returns the exact product of two integers as a long. Introduced in Java 9.
