You
can access the annotations of a class, method, field or parameter at
runtime. Here is an example that accesses the class annotations.
import java.lang.annotation.*; @Retention(RetentionPolicy.RUNTIME) @Target(ElementType.TYPE) public @interface Test { String name(); String value(); }
@Test(name="sample", value="test") public class TestClass { }
import java.lang.reflect.*; import java.lang.annotation.*; public class GetAnnotations { public static void main(String args[]){ Class aClass = TestClass.class; Annotation[] annotations = aClass.getAnnotations(); for(Annotation annotation : annotations){ if(annotation instanceof Test){ Test myAnnotation = (Test) annotation; System.out.println("name: " + myAnnotation.name()); System.out.println("value: " + myAnnotation.value()); } } } }
Output
name: sample value: test
