In Java 6 a better way of interacting with the command prompt was introduced, the java.io.Console class. Together with the utility class java.util.Scanner introduced in Java 5 this new API can be used to develop more advanced Java console applications.
Many times it is useful to be able to get programmatically information about the network interfaces present on a host. Java standard library include a number of classes designed to provide access to this information. The most important is java.net.NetworkInterface which suffered a major face lifting in Java 6.
Due to a number of differences between various platforms it is very difficult to present system specific information in a consistent manner. When getting closer to system specific details, like file system information, a Java programmer has to become aware of the operating system hosting his program in order to make sense of the information [...]
