Patterns in jdk packages

This years last MOD2 task is to find and document at least four (4) different applications of patterns in a java package assigned to you(r group). These package come from the java jdk and are available in source format (in a zip) if you installed the jdk.

Result

You will be using a repository for the whole class in which you find the skeleton of a LaTeX project. You can add your part into that repository. You can also build the project yourselves, provided that you have a LaTeX environment installed on you computer.

You have to add to the repository a .tex file containing a chapter document that describes the application of the patterns found in 'your' package. You may use \sections and \subsections in your chapter. In this description you fill out the following template:

• Name of the package
Per found pattern instance you should describe:
• Names of the classes involved in the pattern instance and the roles in the pattern.
• The reason why this is an instance of the pattern you think it is. (Add related patterns in the comparison).
• Example code using this pattern, showing its use.

The report should be written in the English language.

Strategy for this task

To full fill this task you might want to follow this strategy

• Start with reading the package description. Example: java.nio
• From there look for any class hierarchy. In java.nio that would be something below Buffer for instance.
• Look for members of (1) types from this packages in the classes or for (2)types of classes outside the package. Avoid the last one if you can, although you will not always be able to.
• Try to restrict yourselves to the javadoc api documentation (javadoc level) as long as possible, making assumptions on the patterns used and verify those assumption
• Draw a class diagram
• By committing a automatic build script should start. You should be able to find the product and logfile at the builder website.

Packages for investigation.

Each group of students gets assigned two of the following packages:

Group assignment will be done at the start of the lab hours.
