Factorial a Number Using Recursion in Java

``` A program that will ask the user to give a number and then the program will compute the factorial value of the given number using a recursion algorithm using Java programming language.

Scanner input  = new Scanner(System.in);

System.out.println("\n");
System.out.print("\tFactorial a Number Using Recursion in Java");
System.out.println("\n");
System.out.print("\tGive a Number : ");
num=input.nextInt();

System.out.println();
System.out.println("\tThe factorial("+num+") = "+factorial_recursion(num)+"\n");
System.out.print("\tEnd of Program");
System.out.println("\n");

input.close();

}

static int factorial_recursion(int n)
{
if(n==0)
return 1;
else
return n*factorial_recursion(n-1);
}
