What is a generic interface in Java?
People also ask, what is a generic interface?
Interfaces that are declared with type parameters become generic interfaces. Generic interfaces have the same two purposes as regular interfaces. They are either created to expose members of a class that will be used by other classes, or to force a class to implement specific functionality.
Also, what is generic class in Java with example? Generics in Java is similar to templates in C++. The idea is to allow type (Integer, String, … etc and user defined types) to be a parameter to methods, classes and interfaces. For example, classes like HashSet, ArrayList, HashMap, etc use generics very well. We can use them for any type.
Similarly, how are generic interfaces implemented in Java?
There are 3 ways to implement generic interfaces in Java.
Ways to Implement Generic Interface
- Ignore or Remove Formal Type Parameters.
- Create a Generic Class.
- Create a class that deals with specific non-generic types.
What is the use of generics in Java?
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.
