This chapter provides a number of practical tools and techniques.

• Java Files &Packages - how class file rules and how files are organized into packages, which are the Java version of libraries. Also,
  • Namespace - how Java avoids confusion amon similarly named classes.
  • import - tell compiler where to look for files.
• Access rules - how variables and methods can be hidden or made visible to methods in other classes.
• Constants - the final modifier prevents a property value from changing.
• Static Import - added in Java 5.0, the static import directive shortens the code needed to invoke a static method or access a static variable.
• JARs - "zip" compressed files that hold classes in a compact form.
• CLASSPATH - how classes can find other classes and packages.
• Applet Directories - putting applet classes into sub-directories.
• 3rd Party Packages - using packages in various locations.
• javadoc - automatic docmentation of packages and classes.
• Coding Conventions - a set of suggested coding conventions to maintain a consistent style that is helpful with reading and debugging programs.
