For example, java.util.Stack<E> is a generic class. It supports a single type parameter E. java.util.Stack<E> can be viewed as multiple classes when used with E parameterized to different reference types. Each of them is a variation of java.util.Stack<E>: ...
class GenericArray<T> where T : IComparable { public int Find(T value) { int Find(T value) {...} } } Notice that <T> is going to be a placeholder for specifying the type from the previous class examples. The type binding occurs when instantiating the classes as seen below: var s...

A parameterized type is an instance of a generic type where the type parameters in the formal type parameter list are replaced with type names. Examples include Set<Country> (Set of Country), where Country replaces E in Set<E>; and Map<String, Part> (Map of String keys and Part values...
In addition to the new collections in System.Collections.Concurrent (part of PFX), the .NET Framework 4 includes a new set collection in System.Collections.Generic, called SortedSet<T>. Like HashSet<T>, which was added in .NET 3.5, SortedSet<T> is a collection of unique elements, but ...

WeakReference<T>The existing non-generic WeakReference type has two issues: First, it forces consumers to cast whenever the target needs to be accessed. More importantly, it has a design flaw that makes using it prone to race conditions: it exposes one API to check whether the ...
