Why won't charAt() work?

I need to total the number of lines in a string. In my finite programming wisdom I know that charAt is a valid String method. However when I use it in the code below Eclipse keeps telling me it is not a valid method for my class. What gives?!?!?

Code:

---


public void addClassToSchedule(int index) throws TimeConflictException,
                        NameConflictException {
                String list = allClasses();
                int total = CourseList.howManyItems(all);
                int linenumber = 0;
                String c
                for(int t = 0; t < list.length(); t++){
                                String c = list.charAt(t);
                                linenumber++;
                        }
                }

Never Mind, just used a StringTokenizer instead.

Was there more to the message?
The problem I see is with what charAt() returns.

Code:

---

TestCode5.java:379: incompatible types
found  : char
required: java.lang.String
      String c = "asdf".charAt(1);
                              ^
1 error
vs

  char c = "asdf".charAt(1);

In future post the full and exact error message not your paraphrased interpretation.

Also, you should avoid using string tokenizer and stick to split instead. StringTokenizer is a legacy class only still around for old code.

Look at what the charAt() returns. A String and a char are not compatible types. You need to convert the char to a String.

Hint: Check the Character class.

Yes the String.split is FAR better than the StringTokenizer class. The API even tells you to use the split method to do tokens.
