Java 9 Improved @Deprecated Annotation

Java 9 New Features

The @Deprecated annotation can mark the status of Java API, which can be one of the following:

There is a risk in using it, which may lead to errors
May be incompatible in future versions
May be deleted in future versions
A better and more efficient solution has replaced it.

Java 9 Two new elements have been added to the annotations insince and forRemoval.

since: The element specifies the version in which the annotated API element has been deprecated.
forRemoval: The element indicates that the API element of the annotation will be deleted in future versions and should be migrated to the API.
