Generics was introduced in 2004 in Java programming language. Before the introduction of generics, type safety was not available, which caused program to throw errors during runtime. In this tutorial, we will learn why generics are introduced and how to use them in Java. We will also cover w...
A class or interface that operates on parameterized type is called Generic. Generics was first introduced in Java5. Now it is one of the most profound feature of java programming language.
Genricsis one of the core feature of Java programming and it was introduced in Java 5. If you have been working onJava Collectionsand with version 5 or higher, I am sure that you have used it. Using generics with collection classes is very easy but it provides a lot more features than ...

In this tutorial, you’ll learn about generics and see three examples of using them with the Java Collections Framework. I’ll also introduce raw types and discuss the instances when you might choose to use raw types rather than generics, along with the risks of doing so. ...
Many of Java's built-in utility classes and interfaces are designed to allow generic type parameters. 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 ...
Tip: We can use@SuppressWarnings("rawtypes")annotation to suppress the compiler warning, check outjava annotations tutorial. Also, please note that it supportsjava autoboxing. Java Generic Interface Comparable interface is a great example of Generics in interfaces and it’s written as: ...
In a nutshell, generics enable types (classes and interfaces) to be parameters when defining classes, interfaces and methods. Much like the more familiar formal parameters used in method declarations, type parameters provide a way for you to re-use the same code with different inputs. The ...
you can use the compiler's error messages to figure out what the problem is and fix it, right then and there. Runtime bugs, however, can be much more problematic; they don't always surface immediately, and when they do, it may be at a point in the program that is far removed from...
