Chapter 1. Java Basics
This chapter contains examples that demonstrate the basic syntax of
Java; it is meant to be used in conjunction with
Chapter 2 of Java in a Nutshell. If
you have substantial programming experience with C or C++, you should
find the material in this chapter straightforward. If you are coming
to Java from another language, however, you may need to study the
examples here more carefully.The most important step in learning a new programming language is
mastering the basic control statements of the language. With Java,
this means learning the if/else branching
statement and the while and for
looping statements. Learning to program well is like learning to do
word problems in high-school algebra class: you have to translate the
problem from an abstract description into the concrete language of
algebra (or, in this case, the language of Java). Once you learn to
think in if, while, and
for statements, other Java statements, such as
break, continue,
switch, and try/catch/finally,
should be easy to pick up. Note that although Java is an
object-oriented language, we won't discuss objects
until Chapter 2.
So, with that as an introduction, and with mastery of basic syntax as
our goal, let's jump right in and start writing Java
programs.
