Generators? Wrapper classes? Wow, sounds too hardcore for me.. ;) Peter, I think Matt is already being very specific by giving u the link to the book itself. Do you want him to even look for the exact page where the exact problem is for you? Come on, it's your assignment, do some work please. An advice for that little problem of "make me forget the little I have learnt", write watever u have learnt down in a journal or a paper ;). Then u won't forget them. From what i can see, these methods are for : charAt() - to get the specific character from the string, and possibly the array, and compare both to see whether it's equal or not.
String str="boogalooga";
for(int i=0;i {
char ch=str.charAt(i); // gets the certain character
// from here you get your character from the array
// and compare it, if it's equal, add the counter in
// your counter array or if you don't want to fetch every
// single character, look at the indexOf() explanation below.
}
indexOf() - well this is just to save you from looking at redundant characters, rather than checking every characters from the *beginning* of the array of either your string or character list (you can store your character list as a string, or well, an array), you just use indexOf() to get the first occurence of the character. > I would like to complete this problem in the simplest way possible...

Maps are often used to solve these categorizing problems. You can easily find such examples in the tutorials. You could also find an example of this exact problem in Bruce Eckel's Thinking in Java book, which you can get online for free at his web site.
