Note: Recompile with -Xlint:unchecked for details.

You can simply ignore those warnings if you wish to do so. Otherwise, you can learn how to eliminate the warnings by doing the following:

  • Go to Object-Oriented Programming (OOP) with Java
  • Open Contents
  • Open ITSE2317 - Java Programming (Intermediate)
  • Open Generics
  • Open Java4210: Getting Started with Generics
  • Study that module and the seven modules following it as listed in the Contents.


This section contains a variety of miscellaneous information.
