What are some practical use cases for Java lambda expressions?

Java lambda expressions are used to implement functional interfaces, enabling cleaner and more concise code. Common use cases include sorting collections, filtering data, and event handling.

Can you give me an example of using lambda expressions for sorting a list?

Sure! You can use lambda expressions with the Collections.sort() method. For example: Collections.sort(list, (a, b) -> a.compareTo(b)); This sorts the list in natural order.

How do lambda expressions improve code readability?

Lambda expressions reduce boilerplate code, making it easier to read and understand. They allow you to express actions in a more direct way, focusing on what to do rather than how to do it.

Are there any performance benefits to using lambda expressions?

Yes, lambda expressions can improve performance by enabling lazy evaluation and reducing the overhead of anonymous classes, especially in large data processing tasks.
