Hi Hans,
you can't create an instance of a FilterInputStream directly, cause the Constructor is protected.
You should use one of the already defined subclasses, for example BufferedInputStream...
Or you can define your own FilterInputStream by subclassing FilterInputStream.
Hope that helps
Oliver

Pay attention to FileInputStream 's constructors:
FileInputStream(File file)
FileInputStream(FileDescriptor fdObj)
FileInputStream(String name)
System.in is an InputStream
how can it be taken as a parameter to FileInputStream 's constructors?
