There are three parts to this activity. Before you write a Java program for this activity, write the pseudocode for this program. Also, create the activity diagram for this program. Turn in the pseudo-code, UML activity diagram, and Java program. Create a program, call this Java class Factorial that prompts the user for an integer number. The program returns the factorial of the number. O! = 1 In your program, answer the following question: What kind of loop are you using for this example? Counter-controlled loop or sentinel controlled loop? Explain. Sample Input Enter a number: 8 Sample Output 8! = 8 * 7 * 6* 5 * 4 * 3 * 2 * 1 = 40320 Sample Input Enter a number: 3 Sample Output 3! = 3 * 2 * 1 = 6
