What are Java lambda expressions?

Java lambda expressions are a feature introduced in Java 8 that allows you to write anonymous functions. They enable you to treat functionality as a method argument, which can lead to more concise and readable code.

Can you give me an example of a lambda expression?

Sure! Here's a simple example: List<String> names = Arrays.asList("Alice", "Bob", "Charlie"); names.forEach(name -> System.out.println(name)); This lambda expression prints each name in the list.

What are the benefits of using lambda expressions?

Lambda expressions make your code more readable and concise. They also enable functional programming features like streams, which can simplify operations on collections.

Are there any drawbacks to using lambda expressions?
