Build your own Java library

Greg Travis (mito@panix.com), Programmer, 自由职业者
Greg Travis is a freelance programmer living in New York City. His interest in computers can be traced back to that episode of "The Bionic Woman" where Jamie is trying to escape a building whose lights and doors are controlled by an evil artificial intelligence, which mocks her through loudspeakers. Greg is a firm believer that, when a computer program works, it's a complete coincidence.

Summary:  This tutorial reviews how the Java language can help you make a good, reusable library. It covers the key principles of good library design and the most efficient ways to implement each of these ideas in the Java language.

Tutorial tips

Should I take this tutorial?

Code reuse is one of the Holy Grails of computer programming. Writing code that can be easily reused is a difficult skill, but certainly one that can be mastered.

In this tutorial, you will learn:

  • How the Java language can help you make a good, reusable library
  • A few of the key principles of good library design
  • The most efficient way to implement each of these ideas in the Java language

To illustrate these ideas, we'll walk through the design of a simple library.

To use this tutorial successfully, you'll need to have a basic understanding of Java programming, including the ability to create, compile, and execute simple command-line Java programs.

Objectives

When you complete this tutorial, you will:

  • Know the major obstacles to code reuse
  • Have a working knowledge of the ideas behind library design
  • Know how to implement these ideas in the Java language
  • Possess an excellent design of a Java library as a sample for future projects
