@MyAnnotation public class MyClass { // class implementation } MyClass.class.getAnnotations(); // returns an array containing the @MyAnnotation annotation
@MyAnnotation(value = "Hello") public class MyClass { // class implementation } MyAnnotation annotation = MyClass.class.getAnnotation(MyAnnotation.class); String value = annotation.value(); // returns "Hello"In this example, the @MyAnnotation annotation has a value parameter that is set to "Hello". The getAnnotation method is called on the MyClass class, passing in the MyAnnotation class as an argument. This method returns a single instance of the @MyAnnotation annotation, which is then used to retrieve the value of the value parameter. Based on these examples, it is difficult to determine which package library is being used. The annotations used in the examples are custom annotations that could be defined in any package in the Java language or in a third-party library.
