Character ammount

[.righteous]

I've just finished watching your tenth "Learning Java" part and I want to limit the character number to five digits only. 
I've tried this:

Code:

import java.util.*;
public class digitExtractorTester {
    static Scanner userInput = new Scanner(System.in);
    
    public static void main(String[] args){
        String rNumber = "12345";
        System.out.print("Enter a custom, five digit number: ");
        String nSequence = userInput.next();
        System.out.println(" ");
        if (nSequence.chars() != rNumber.chars()){
            System.out.println("Your input contains too many or too less digits.\nOnly five digit numbers are allowed.");
        }
        else{
        digitExtractor byMath = new digitExtractor(Integer.valueOf(nSequence));
        byMath.returnNumberSequenceByMath();
        System.out.println(" ");
        digitExtractor byChar = new digitExtractor(nSequence);
        byChar.returnNumberSequenceByChar();
        }
    }
}

But it doesn't seem to be working. Any suggestions?

Never mind. I solved my own problem.
If anyone's wondering, I was using chars() when I was supposed to be using length(). (Source of information)

Code:

nSequence.length() != rNumber.length()
