We may be asked to write a program tocalculate factorialduring coding exercises inJava interviews. This always better to have an idea of how to build such a factorial program. 1. What is Factorial? The factorial of a number is theproduct of all positive descending integersup to1. Factorial ...

// Java program to calculate factorial of a // number using recursion import java.util.*; public class Main { public static long getFactorial(int num) { if (num == 1) return 1; return num * getFactorial(num - 1); } public static void main(String[] args) { Scanner X = new ...
The factorial of 7 is 5040 Note: To test the program for a different number, change the value of num. Here, the number whose factorial is to be found is stored in num, and we check if the number is negative, zero or positive using if...elif...else statement. If the number is ...

Output: Factorial of the number. Example: Input: 5 Output: 120 Solution 1: Factorial Calculation using Loops Code: import java.util.Scanner; public class FactorialUsingLoop { public static void main(String[] args) { Scanner scanner = new Scanner(System.in); ...
To find the factorial, fact() function is written in the program. This function will take number (num) as an argument and return the factorial of the number.# function to calculate the factorial def fact(n): if n == 0: return 1 return n * fact(n - 1) # Main code num = 4 #...
1.write a program which computes and prints prime numbers 2. write a program which computes and prints the factorial of a number
1.BigIntegerclass is in java.math package, so you need to specifically import it, it will not be imported automatically like java.lang package. 2. Similar to String,BigIntegerclass is also immutable, so any modification e.g. addition, multiplication will produce a new instance ofBigInteger, le...
