What are some real-world examples of generics in programming?
Generics are widely used in programming languages like Java and C#. For example, in Java, the Collections framework uses generics to allow for type-safe data structures.
Can you give me a specific example of a generic class?
Sure! A common example is the ArrayList<T>
class in Java, where T
can be any object type, allowing for a list of any data type.
How do generics improve code reusability?
Generics allow you to write a method or class once and use it with different data types, reducing code duplication and increasing maintainability.
Are there any downsides to using generics?
One downside is that they can introduce complexity, making the code harder to read for those unfamiliar with generics. Additionally, type erasure in Java can lead to runtime issues.
