What are lambda expressions in Java?

What are lambda expressions in Java?

Lambda expressions in Java are a way to provide clear and concise syntax for writing anonymous methods. They enable you to treat functionality as a method argument, or to create a concise way to express instances of single-method interfaces (functional interfaces).

Can you give me an example of a lambda expression?

Sure! Here's a simple example: Runnable r = () -> System.out.println("Hello, World!"); This creates a lambda expression that implements the Runnable interface.

How do lambda expressions improve code readability?

Lambda expressions improve code readability by reducing boilerplate code. They allow you to express instances of functional interfaces in a more concise way, making the code easier to understand.

Are there any limitations to using lambda expressions?

Yes, lambda expressions can only be used with functional interfaces, which are interfaces with a single abstract method. They also cannot access non-final local variables.
