Why won't charAt() work?

[MetalR0]

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?!?!?

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.

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.
