Before Java 8 if you needed to use multiple instances of the same annotation, they had to be wrapped in a container annotation. With Java 8, that's no longer necessary, allowing for cleaner, more readable code.
@SomeAnnotations({ @SomeAnnotation(..a..), @SomeAnnotation(..b..), @SomeAnnotation(..c..), }) public class SomeClass { ... }
@SomeAnnotation(..a..) @SomeAnnotation(..b..) @SomeAnnotation(..c..) public class SomeClass { ... }
