for making a dictionary with word-meaning, how you will maintaing the data. (ANS - Map)
If I have to store two meaning for the same word, how I will do that. (ANS - for every key store arraylist of meanings).
Why not array. (ANS - array is of fixed lenght, restriction. ArrayList have in build method to operate on data, flexible.)

Use of properties file in servlets. We need to pass full path to load() method. getContextPath("\") - will give path of working dir and getContextPath("/WEB-INF") will give path upto webinf of application - use these.
