Chapter 2. Simple programs
2.1 Three starter programs
2.2 The structure of a program
2.3 Basics of object orientation
2.4 Beginning with output
2.5 Simple calculations
In this chapter we give a broad overview of the different parts of a Java program and how they fit together. Using three carefully chosen examples, we are able to explain the concepts of object-oriented programming so that, by the end, we shall be able to create and run simple programs that have tangible results.
