Streams 289

You can work with this input stream like any other. The following statement
creates a buffered input stream associated with the System.ininput stream:

BufferedInputStream bin = new BufferedInputStream(System.in);

The next project, the Consoleclass, contains a class method you can use to
receive console input in any of your Java applications. Enter the text from
Listing 20.2 in a new empty Java file named Console.
