How does generics overview impact performance or memory usage?

Generics in Java allow for type-safe operations on collections and other data structures, enhancing code reusability and maintainability. This can lead to slight performance improvements as type casting is minimized, but the impact on memory usage may vary depending on the specific implementation of generics. Understanding the nuances of generics is essential for optimizing applications.

// Example of generics in Java import java.util.ArrayList; import java.util.List; public class GenericExample { public static void main(String[] args) { List stringList = new ArrayList<>(); stringList.add("Hello"); stringList.add("World"); for (String item : stringList) { System.out.println(item); } } }
