You want us to do your homework... It's not a good thing... As for your question just use String classes and it's methods to do what you need. There is a lot of methods that can help you to accomplish your thing.

Yes, it is quite easy. There are several ways to do it; in fact a search of JavaRanch will probably reveal old threads about similar problems.

you didn't read the API very diligently,

no, there's no "now many Xs are there" method,

but there are �
a) what's the index of X (starting at index i)
b) break the string into pieces, using X as a delimiter
c) what's the character at index i

any could be used to answer your question in several lines of code (or one line, if obfuscation is your cup of tea)
