CHAPTER 5 --- Introduction to Java

The previous chapters have discussed computer hardware, computer software, bits and bytes, machine language, language translation, language interpretation, and virtual machines. This chapter assumes that you know all that and are ready to look at Java.

Chapter Topics:

  • Hello World program.
  • Java Bytecodes.
  • Java compiler and Java virtual machine.
  • Using "Notepad" to create a source program.
  • Running a Java program.
This chapter will assume that you are working on a computer that has the Java Development Kit (JDK) version 1.1 or higher installed. The current release is version 1.2, but the earlier version will do for these notes and may be easier to obtain (on a CD for a book you already have, for instance.)
