Plz can anybody help me.i want to store some records in files.i m working on a teacher told me to use tokens.i dun have any idea about that.plz help me thanx in advance

Where in your code are you having problems?

Did you miss the class where your teacher defined what a token is?
A sort of generic definition would be some characters that are separated from other characters by some delimiter,
For example if ; is the delimiter: "xx;ttttt;uuu" would have three tokens: xx, ttttt and uuu
Or if spaces are the deliliter: "this 123 that" would have 3 tokens: this, 123 and that
