In computer programming, a collection is an abstract data type that is a grouping of items that can be used in a polymorphic way. Often, the items are of the same data type such as int or string . Sometimes the items derive from a common type; even deriving from the most general type of a programming language such as object or variant .
The Java programming language's Java Collections Framework version 1.5 and later defines and implements the original regular single-threaded Maps, and also new thread-safe Maps implementing the java.util.concurrent.ConcurrentMap interface among other concurrent interfaces. [1]

In the Java Collections Framework, the class List<MyClass> represents an ordered collection of objects of type MyClass. Upper bounds are specified using extends : A List<? extends MyClass> is a list of objects of some subclass of MyClass , i.e. any object in the list is guaranteed to be of type MyClass , so one can iterate over it using a ...
In Java, for example, classes are contained in JAR files and objects are created at runtime from the classes. However, in Smalltalk , a class library is the starting point for a system image that includes the entire state of the environment, classes and all instantiated objects.
