TheObjectis the superclass of all other classes, and Object reference can refer to any object. These features lack type safety. Generics add that type of safety feature. We will discuss that type of safety feature in later examples. Generics in Java are similar to templates in C++. For exa...

C# generics allows us to create a single class or method that can be used with different types of data. In this tutorial, you will learn about the C# generics with the help of examples.
This Java Generics tutorial shows examples of how to use generic type parameters with some of these classes. Once you have seen a few examples, you can figure out how to use generic type parameters in general. You can also design your own classes, interfaces and methods to use usable ...
Java's collections framework offers many examples of generic types. For instance, the java.util package includes Set<E>, which consists of the Set interface and type parameter E (identifying the set's element type). Also, this package includes Map<K, V>, which consists of the Map interface...
