With the help of generics in Java, we can write code that will work with different types of data. For example, public <T> void genericsMethod(T data) {...}.

The Java Generics programming is introduced in J2SE 5 to deal with type-safe objects. It makes the code stable by detecting the bugs at compile time. Before generics, we can store any type of objects in the collection, i.e., non-generic. Now generics force the java programmer to store a specific type of objects.

Mar 01, 2016 · Generics in Java. Generics means parameterized types. The idea is to allow type (Integer, String, … etc., and user-defined types) to be a parameter to methods, classes, and interfaces. Using Generics, it is possible to create classes that work with different data types. An entity such as class, interface, or method that operates on a ...

Oct 24, 2020 · Java Generics was introduced to deal with type-safe objects. It makes the code stable.Java Generics methods and classes, enables programmer with a single method declaration, a set of related methods, a set of related types. Generics also provide compile-time type safety which allows programmers to catch invalid types at compile time.

How are Generics Implemented in Java? Generics are implemented using angular brackets “<>”. The brackets enclose the type parameter “T” within them. For Example, <T>. The type parameter “T” is a place holder, indicating that a data type will be assigned to it at run time. For example, a generic class will be defined as: Code:
