Print my recursive factorial result

I need to print my final answer for my method. However, it shows the whole calculation to the end! How can I eliminate the process to get only the result?

Solution

  • This is a recursive function call, which is executed in all the cases without special condition checks. printing from another method is a good option.

    private static int getFactorial(int userInput){
    int ans = userInput;
    if(userInput >1 ){

    ans*= (getFactorial(userInput-1));
    }
    return ans;

}
// New method;
private static void printFactorial(int userInput){
    System.out.println("The value of " + userInput + "! is " + getFactorial(userInput));
}
