Java is a concurrent, class-based, object-oriented programming language designed to run with as few implementation dependencies as possible. Developers use Java because of its robust community of programmers, relative stability, and ubiquity.
Java Generic Type Naming convention helps us understanding code easily and having a naming convention is one of the best practices of Java programming language. So generics also comes with its own naming conventions. Usually, type parameter names are single, uppercase letters to make it easily dis...
