* A program element annotated &#64;Deprecated is one that programmers

* A program element annotated {@code @Deprecated} is one that programmers
* are discouraged from using. An element may be deprecated for any of several
* reasons, for example, its usage is likely to lead to errors; it may
* be changed incompatibly or removed in a future version; it has been
* superseded by a newer, usually preferable alternative; or it is obsolete.
*
* <p>Use of the &#64;Deprecated annotation on a local variable
* declaration or on a parameter declaration or a package declaration
* has no effect on the warnings issued by a compiler.
* <p>Compilers issue warnings when a deprecated program element is used or
* overridden in non-deprecated code. Use of the {@code @Deprecated}
* annotation on a local variable declaration or on a parameter declaration
* or a package declaration has no effect on the warnings issued by a compiler.
*
* <p>This annotation type has a string-valued element {@code since}. The value
* of this element indicates the version in which the annotated program element
* was first deprecated.
*
* <p>This annotation type has a boolean-valued element {@code forRemoval}.
* A value of {@code true} indicates intent to remove the annotated program
* element in a future version. A value of {@code false} indicates that use of
* the annotated program element is discouraged, but at the time the program
* element was annotated, there was no specific intent to remove it.
*
* @apiNote
* It is strongly recommended that the reason for deprecating a program element
* be explained in the documentation, using the {@code @deprecated}
* javadoc tag. The documentation should also suggest and link to a
* recommended replacement API, if applicable. A replacement API often
* has subtly different semantics, so such issues should be discussed as
* well.
*
* <p>It is recommended that a {@code since} value be provided with all newly
* annotated program elements. Note that {@code since} cannot be mandatory,
* as there are many existing annotations that lack this element value.
*
* <p>There is no defined order among annotation elements. As a matter of
* style, the {@code since} element should be placed first.
