OO Programming Principle: A Game In-Text GuessInt

Abstract

This chapter starts learning Java with games. Some simple games deal with Strings only. We call them as games in-text. We selected one of such game as our starting point. The game is called GuessInt that is a two persons’ verbal guessing game. One person thinks of an integer between 1 and 100. The other person guesses what the integer would be. From the story of the game to a pseudo code and finally to an implementation, the entire process demonstrates the object-oriented programming principle, discusses several important Java control statements, and touches the try-catch block for exception handling.
