Today during studying xMule project I heard of the discussion among my workmates and a customer. The quesiont which they are
talking about is HashMap in Java. There are several our project managers and an advance project manager. They all but one
seems to forget what is hash codes and its purpose. Or someone from them might never know the essence of hash code.
The hash code is just to used to make a one to one map between data and hash code. In a sense, you can compare it to a subscript,
such as the subscript of array. The discrepancy between them is just that a hash code usually is made from a user input data.
Nowadays more and more developing tools and developing packages make programmers easy to code a program, and make them to forget
those base knowledges.
