The LinkedList uses the diamond syntax (<>) to let the compiler infer the generic type parameters. Since lines is a List<String>, LinkedList<> is expanded as LinkedList<String>. The diamond operator makes dealing with generics easier by avoiding repeating types when they can easily be inferred...
Entities that own embeddable classes as part of their persistent state may annotate the field or property with thejavax.persistence.Embeddedannotation but are not required to do so. Embeddable classes may themselves use other embeddable classes to represent their state. They may also contain collection...
