# Java Program to Find a Factorial of a Number using Recursion1 min read

In this example, we will calculate the factorial of a number taking the value from the user.
You can also learn to find the Factorial of a Number in Java Using for loop.

Recursion refers to the function calling itself inside its function in a program.

Before we begin, you should have the knowledge of the following:

Factorial of n number: Factorial of n number is the product of all the positive descending integers and is denoted by n!.
Example:

factorial of n (n!) = n * (n-1) * (n-2) * (n-3)….1
factorial of 5 (n!) = 5 * 4 * 3 * 2 * 1
NOTE: Factorial of 0 (0!) = 1

## Factorial Program using Recursion in java.

Output:

`Enter the number: 4 Factorial of entered number is: 24`
