4.6. Review

Java command-line parameters are not that different from C/C++ command-line parameters. Environment variables are a different story. Most of the shell's environment variables are not readily accessible, and we looked at how you might deal with this situation.

We have discussed, among other things, some uses for these classes: java.util.Properties, java.lang.System, and java.lang.Runtime, but we have only barely scratched the surface. There are many more methods available in these classes with which you can do lots more.
