Java Program To Find Out The Factorial Of A Number

Java Program To Find Out The Factorial Of A Number 

=====================================================================

import java.util.Scanner;

public class Factorial {

    public static void main(String[] args) {

        // A factorial is a function that multiplies a number by every number below it
        // till 1.
        // Example : 1) 5! = 5*4*3*2*1

        Scanner sc = new Scanner(System.in);
        System.out.println("Enter the Number:");
        Integer number = sc.nextInt();
        Integer fact = 1;
        for (int i = 1; i <= number; i++) {
            fact = fact * i;
        }
        System.out.println("The Factorial Of the Number is :" + fact);

    }

}


Output:
================
Enter the Number:
7
The Factorial Of the Number is :5040

How many primitive data types are there in Java?

Java includes a set of fundamental data types known as primitive data types. These data types are the essential components for storing and managing various kinds of data, including numbers, characters, and boolean values. Java encompasses a total of eight primitive data types, and this article aims to provide an in-depth explanation of each type in a simplified manner. 1.      byte: The byte data type is designed for storing small integer values, with a range spanning from -128 to 127. 2.      short: Slightly more accommodating than byte , the short data type can be employed for storing relatively larger integer values, ranging from -32,768 to 32,767. 3.      int: Among the most commonly used primitive data types, int can hold larger integer values, with a range extending to approximately -2 billion to 2 billion. 4.      long: When dealing with very large integer values, the long data t...
