Calculating a factorial of a number is a straightforward task. A factorial of a number is the product of that number (positive integer) and all positive integers less than that number. In other words - multiplying a number by all of the whole numbers from that number to 1. 0! equals 1...
The factorial of a positive integer is the product of all positive integers less than or equal to this number, and the factorial of 0 is 1. The factorial of a natural number n is written as n!. In 1808, Keston Kaman introduced this notation....
1. What is Factorial? The factorial of a number is theproduct of all positive descending integersup to1. Factorial ofnis denoted by'n!'. For example, we may write the factorial of 5 as: Factorial of 5 5!=>5*4*3*2*1=>120
Java Method is a collection of statements to process some specific task and return the response to the caller. Methods allow us to write reusable code and dividing our program into several small units of work. Java Method promotes clean and more readable code. ...
