Some context perhaps?
For starters, it's deprEcated. Deprecated in the context of API docs means "sort of obsolete". If a class or method is javadoc'd or annotated as deprecated, it means it may at some point disappear from the API, but it's still there for the time being. Usually it is indicated what the preferred replacement is.
So, you should not use deprecated classes/methods in any new code, and at some point may have to rework your old code to use the preferred way.
