What are the best practices for using generics in Java?

What are the best practices for using generics in Java?

Some best practices include using bounded type parameters, avoiding raw types, and using wildcards appropriately.

Can you explain what bounded type parameters are?

Bounded type parameters allow you to restrict the types that can be used as arguments in generics, enhancing type safety.

What are raw types and why should I avoid them?

Raw types are the non-generic versions of parameterized types. They should be avoided as they bypass generic type checks, leading to potential runtime errors.

How do wildcards work in generics?

Wildcards in generics allow for flexibility in specifying types. You can use '?' to represent an unknown type, which can be bounded or unbounded.

Can you give an example of using generics in a Java class?

Sure! Here's a simple example: public class Box<T> { private T item; public void setItem(T item) { this.item = item; } public T getItem() { return item; } }.
