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.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);
	}
