Writing Java Classes, Using Case Studies

Ok, After understanding nstance variables, class variables, clas methods, comments, e.t.c and you want to write a class. Is there anyone in the house who can teach writing Java classes using simple case studies to prime our young brains into becoming a matured programmer.

I will appreciate java programmers in the house giving us tutorials on writing Java classes using case studies. SBU career, Mimoh mi, smartsoft, codec and others, where are you?,

Help us out.

lets assume i want to write a java class which basically reques that a user input words once at a time. Lets say , that if after all the words have been inputted, the user should then enter "£" when the next word is requested. The method should then retun the average length of the words that were inputted ( not including the "£").

Les assume that the user input valid words and at least one word is inputted.
