Question

Factorials (JAVA)

by CodeChum Admin

For those of you who may not now, a factorial is a product of multiplying from 1 until the number. Now, you must make a program that will accept an integer and then print out its factorial using loops.

Are you up for this task?

Instructions:

1. Input a positive integer.
2. Using a for() loop, generate the factorial value of the integer and print out the result.
3. Tip #1: Factorials work like this: Factorial of 5 = 1 * 2 * 3 * 4 * 5
4. Tip #2: There's a special case in factorials. The factorial of 0 is 1.

Input

A line containing an integer.

5

Output

A line containing an integer.

120

Answer 1

public static int getFactorial(int f) {
  int result = 1;
  for (int i = 1; i <= f; i++) {
     result = result * i;
  }
  return result;
}
