Best Ways to Java Generic Naming Convention, Rules, Examples

In this post, We will learn what are the naming conventions rules for Generic type parameters. Many people might have seen that Generic types are heavily used in Java Collection api such as ArrayList, HashSet, HashMap.

Generics types are should be enclosed in Diamond operator.

Java Type Inference in Generics

Type Inference in Generic

In Java 7, Type Inference is introduced in generics declaration which is used to reduce the coding as well to minimize the compile errors.

Made compiler smart enough to infer the type of generic instance. This is done by using "<>" operator and it is called as Diamond Operator. Not required to mention the type in between diamond operator and can be replaced declaring the type as left blank.
