What are the differences between Java lambda expressions and anonymous classes?

What are the differences between Java lambda expressions and anonymous classes?

Java lambda expressions are a more concise way to represent functional interfaces, while anonymous classes are more verbose.

Can you give me an example of each?

Sure! A lambda expression might look like this: list.forEach(item -> System.out.println(item));. An anonymous class would be: new Runnable() { public void run() { System.out.println("Hello"); } }.

Which one is preferred in modern Java?

Lambda expressions are generally preferred for their simplicity and readability, especially in functional programming.

Are there any performance differences?

Yes, lambda expressions can lead to better performance due to optimizations in the JVM, especially in cases of repeated use.
