java.util Class Collectionsjava.lang.Object java.util.Collections public class Collections extends ObjectThis class consists exclusively of static methods that operate on or return collections. It contains polymorphic algorithms that operate on collections, "wrappers", which return a new collection backed...
Java 1.5 came up with thread-safe collection classes that allowed us to modify Collections while iterating over them. Some of them are CopyOnWriteArrayList, ConcurrentHashMap, CopyOnWriteArraySet. These classes are in java.util.concurrent package. All the collection classes are present in java.util a...
Choices in Materializing Collections In your application, you have the choice of materializing a collection as an instance of theoracle.sql.ARRAYclass, which is weakly typed, or materializing it as an instance of a custom Java class that you have created in advance, which is strongly typed. Cu...
