What properties does the @Deprecated annotation add in Java 9?

Two new parameters or properties have been added in the @Deprecated annotation in Java 9. These parameters are Since and forRemoval, these two parameters are optional when we cannot specify them, with default values.

Because

this string parameter specifies a deprecated version of the API. The default value for this element is emptystring.

Syntax

<strong>@Deprecated(since="<version>")</strong>

forRemoval

This Boolean parameter specifies whether the API is intended to be removed in a future release. When we cannot specify, the default value is false.

Syntax

<strong>@Deprecated(forRemoval=<boolean>)</strong>

Example

public class DeprecatedAnnotationTest {
   public static void main(String[] args) {
      DeprecatedAnnotationTest test = new DeprecatedAnnotationTest();
      test.method1();
      test.method2();
   }
<strong>   @Deprecated(since="7.0")</strong>
   public void method1() {
      System.out.println("@Deprecated(since=\"7.0\")");
   }
<strong>   @Deprecated(since="5.0", forRemoval=true)</strong>
   public void method2() {
      System.out.println("@Deprecated(since=\"5.0\", forRemoval=true)");
   }
}

Output

<strong>@Deprecated(since="7.0")
@Deprecated(since="5.0", forRemoval=true)</strong>
