Type Parameters Java

In Java, type parameters are a fundamental aspect of generics, allowing developers to create classes, interfaces, and methods that can operate on various data types while maintaining type safety. A type parameter is essentially a placeholder for a specific type that will be specified when an instance of a generic class or method is created. This enables the creation of more flexible and reusable code.

Type parameters are defined using angle brackets (<>). For example, in a generic class declaration like public class Param<T>, T is the type parameter. You can also have multiple type parameters, separated by commas, such as in public class Test<K, V>, where K and V can represent different types of values stored in the class ¹³.

Using type parameters helps eliminate the need for type casting and reduces the risk of runtime errors due to type mismatches. This feature was introduced in Java 5 to enhance code clarity and robustness ².
