ABSTRACT
The main difference between a computer and a calculating machine is that the computer can make simple decisions. Programs are able to process information logically because of this decision-making ability. The result of a program decision is to direct program execution in one direction or another one, that is, to change program flow. One of the most important tasks performed by the programmer is the implementation of the program's processing logic. This implementation is by means of the language's decision constructs. In this chapter you will learn how a Java program makes decisions.
