Table of Contents
Part I:  Java Foundation

In this chapter you will learn:

  • Java's keywords

  • Data types used in Java

  • Java variables

  • How memory is organized and how it is interpreted by Java variables

All programming languages define a set of keywords that represent instructions to the programming language compiler; data types that define how memory is allocated for items in memory such as numbers and characters; and variables that are used to name a region of memory. This chapter describes how these concepts are implemented in the Java programming language.
