Write a java program that will

Invoke (call) a method calcFact that will

  • receive an integer from main after itis obtained from user
  • use recursion to calculate the factorial of that integer
  • from main, print the factorial of the integer
Expert Solution
Step 1

Java Program:

import java.util.*;

class CalcFactClass{
 public static void calcFact(int n){
  int prod = 1;
  for(int i=n; i>0; i--){
   prod *= i;
  }
  System.out.println("Factorial = " + prod);
 }
 public static void main(String args[]){
  Scanner in = new Scanner(System.in);
  System.out.println("Enter an integer");
  int n = in.nextInt();
  CalcFactClass.calcFact(n);
 }
}
