Generics are a facility of generic programming that extend Java's type system to allow a type or method to operate on objects of various types while providing compile-time type safety. In particular, the Java collections framework supports generics to specify the type of objects stored in a collecti...

Generic code enables you to write flexible, reusable functions and types that can work with any type, subject to requirements that you define. You can write code that avoids duplication and expresses its intent in a clear, abstracted manner. Generics are one of the most powerful features of Swi...
A List can hold numbers, words or really anything. That's why we call the List generic. Generics are basically used to define which types a class can hold and which type an object currently holds. class ClassName<TypeName> class ClassName<*> ClassName<in UpperBound> Clas...
The generic types declared within the triangle brackets: <T> Constrainting the generic types is done with the extends keyword: <T extends Car> The generic parameters are not available at runtime, they are just for the compile time. This means you can't do something like this: ...
Generics allow you to define placeholders for exact types in definitions for classes, interfaces and/or methods. Possible subtopics: Class (and structure) generics Interface generics Method generics Constraints Covariance and contravariance

The class is called ExpressionBuilder. It has three properties: private static readonly MethodInfo ContainsMethod = typeof(string).GetMethod("Contains", new[] { typeof(string) }); private static readonly MethodInfo StartsWithMethod = typeof(string).GetMethod("StartsWith", n...
Generic views are views that perform a certain pre-defined action, like creating, editing or deleting objects, or simply showing a template. Generic views have to be distinguished from functional views, which are always hand-written to perform the required tasks. In a nutshell, it can be said that ...
