A resource is a file situated somewhere in the class path. It can be a file in a package folder, in the classes folder or in a jar file. Resources are usually needed at runtime and they can be properties files, images and so on. The ClassLoader and Class classes provide methods to find the [...]

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.
