Thread: Help please!

here is my code:

package program3;
 
 
public class caesarCipher {
 
    public static void main(String[] userString) {  //userString is the string supplied by the user as an argument
 
        rot13(userString);  //call method rot13 to apply the caesar cipher on the string
        System.exit(0); //exit program
 
 
    }
 
    private static void rot13(String[] userString) {
 
        char[] rot = new char[10];
        rot = userString.toCharArray();   //stores the character from the string currently being ciphered
 
 
 
        }
}

Netbeans gives me an error: "cannot find symbol". I googled a bit and from my understanding it is an issue with class names and the static modifier. I could just copy paste code from there and make it work, but can someone please explain the nuances behind this?
PS : program isn't finished yet

You should read the documentation on the String class. Check that you are actually using a method that is defined for the class.

It is listed as a valid method over here. Is my implementation wrong?

I misspoke.

What type of object is toCharArray() a method for?

What type of object have you called toCharArray on? Is it a String? Is it an array of Strings? Is it something else altogether?

Oh gosh! I feel so dumb now

Thank you for your time though!
