Introduction

Java is one of the popular languages. It has gained a lot of craze among the programmers because of its platform independence. Java proves itself flexible in web developers’ view and user-friendly in programmers because they can deploy an application developed in this programming language in all operating systems.

The object-oriented feature of Java provides many ways to reach the pristine code shore and offer good readability. Also, code reusability is simple in Java and avoids code duplication. Along with that, Java provides many predefined methods and libraries for a smooth workflow.

Now coming to our point, we will discuss the implementation of factorial of a number in Java. Many of you might know how to calculate the factorial of a number, but for the people who are new to the term, factorial lets quickly have a look at calculating the factorial of a number.

The symbol denotes the factorial of a number “! “, so the factorial of an integer can denote by n!. And it is equal to the product of all numbers between 1 to n. For example, the factorial of 5 is 120 (1x2x3x4x5).
