Compliant Solution (Accessible Class Variable)
If a program another class intends to use System.in as well as this the InputLibrary class InputLibrary, the program class must use the same buffered wrapper as does this class rather than which is used by InputLibrary, instead of creating and using its own additional buffered wrapper. Consequently, library InputLibrary must make available a reference to the buffered wrapper to support this functionalityfor such classes.
