What are some examples of lambda expressions in Java?

Can you give me some examples of lambda expressions in Java?

Sure! A lambda expression in Java is a concise way to represent an anonymous function. For example, you can use it to implement the Runnable interface like this: Runnable r = () -> System.out.println("Hello, World!");.

That's helpful! Can you show me another example?

Of course! Here's another example using the Comparator interface: Comparator<String> comparator = (s1, s2) -> s1.length() - s2.length(); This lambda compares the lengths of two strings.

How about using lambda expressions with collections?

Great question! You can use lambda expressions with the forEach method in a list. For instance: list.forEach(item -> System.out.println(item)); This prints each item in the list.
