The documentation for the polymorphic algorithms contained in this class generally includes a brief description of the implementation. Such descriptions should be regarded as implementation notes, rather than parts of the specification. Implementors should feel free to substitute other algorithms, so long ...
There is a new family of staticmethods named “of”, which has been added to list, sets, map methods. In three examples, you can see how the code is streamlined between Java 8 and 9 for list, set and map interfaces. In Java 9, the new static factory methods return collection instance...

Note that it is permissible to pass the same collection in both parameters, in which case the method will returntrueif and only if the collection is empty. Added in 1.5. Java documentation forjava.util.Collections.disjoint(java.util.Collection<?>, java.util.Collection<?>). ...

This is the most controversial design decision in the whole API. Clearly, static (compile time) type checking is highly desirable, and is the norm in Java. We would have supported it if we believed it were feasible. Unfortunately, attempts to achieve this goal cause an explosion in the size...

JPQL collection operators and functions (which are described above) are available also as JPA criteria query expressions. The CriteriaBuilder interface provides factory methods for building these expressions, as shown in the following examples:
java.util.concurrent.ConcurrentNavigableMap Many of the modification methods in the collection interfaces are labeledoptional. Implementations are permitted to not perform one or more of these operations, throwing a runtime exception (UnsupportedOperationException) if they are attempted. The documentation fo...
