Summary


Although the Lang package offers a wide suite of packages, it can be hard to keep track of the various capabilities. This chapter provides an overview, but for more detail on the base classes and the time package, see Appendix A

Almost every Java application can benefit from the Lang package. Similarly, many programs can benefit from the Collections package, described in the next chapter.

Project Ideas

Write a Swing user interface to wrap the conversion capabilities of StringEscapeUtils. Compare this with writing a command-line interface for the same capabilities, perhaps using the CLI package described in Chapter 13, "CLI (Command Line Interface)." What are the tradeoffs of this approach?

Create a clock application using the various date and time formats as described in the Time package.
