Java Generics: How to Define a Generic Class

The correct way to define a generic class in Java is:

'B class Person{}'

Here's why:

• Generic Classes: Generics allow you to write code that can work with different types of objects without specifying the exact type until the code is used. The <T> symbol represents a type parameter.

• Syntax: The generic type parameter (e.g., <T>) is placed after the class name, within angle brackets. This indicates that the class will be parameterized with a type.

Let's break down the options:

• A class Person{ } - Incorrect. The <T> should be within angle brackets and after the class name.
• C class Person{} - Incorrect. The generic type parameter should not precede the class name.
• D class Person{} - Incorrect. This defines a regular class without generics.
