This article introduces new added methods of Java 9
An example with new @Deprecated annotation:
@Deprecated(since ="1.5", forRemoval = true)
forRemoval() returns a boolean:
– true means that “this API element is earmarked for removal in a future release”. Who uses the API should notice that, if they don’t migrate away from the API, their code could be break when new release is issued.
– false indicates that the API element is deprecated, but without any specific intent to remove that API in the future. It is just a recommendation to migrate away from this API.
The default value of this element is false.
since() returns a String.
“This string should contain the release or version number at which this API became deprecated.” Although it has free-form syntax, the string should follow the same scheme as the @since Javadoc tag for the project containing the deprecated API.
The default value of this element is the empty string.
