So I did search and read abut every factorial listing on this site but I cannot seem to figure out what is wrong with my code. Iv tried multiple different return methods but they all keep failing. Any ideas?
public class RecursivelyPrintFactorial {
public static void printFactorial(int factCounter, int factValue) {
int nextCounter = 0;
int nextValue = 0;
if (factCounter == 0) // Base case: 0! = 1
System.out.println("1");
}
else if (factCounter == 1) // Base case: print 1 and result
System.out.println(factCounter + " = " + factValue);
}
else { // Recursive case
System.out.print(factCounter + " * ");
nextCounter = factCounter - 1;
nextValue = nextCounter * factValue;
}
return factValue * printFactorial(factValue - factCounter);
}
}
public static void main (String [] args) {
int userVal = 0;
userVal = 5;
System.out.print(userVal + "! = ");
printFactorial(userVal, userVal);
}
}
I have a feeling I have the equation incorrect in my return but iv tried every combination I can think of. Its driving me insane. Every one reports an error. Any ideas?
return factValue * printFactorial(factValue - factCounter);
I assume that you should be using the "next" values instead of these.
Edit: Also note that the function takes two parameters and is void. Returning factValue times void doesn't make sense.
