How to Write a Factorial Function in Java

Hey there, fellow programmer! Welcome to this blog post, where we are going to guide you through the sequence of steps involved in coding a factorial function in Java. Factorial of a number is the product of all positive integers from 1 to that number and is an important concept in mathematics. We'll keep it simple and straightforward. Let's get started, keep reading!

Mathematical principle

The factorial of a non-negative integer `n` is the product of all positive integers less than or equal to `n`. It is denoted by `n!`. For instance, `5! = 5 x 4 x 3 x 2 x 1 = 120`. The factorial function can be defined by the product `n! = n*(n-1)!`, and `0!` is defined to be `1`.
