What are the differences between anonymous classes and lambda expressions?

What are the differences between anonymous classes and lambda expressions?

Anonymous classes are used to create a one-time use class without a name, while lambda expressions provide a concise way to represent a function.

Can you give me an example of when to use each?

Sure! Use anonymous classes when you need to implement an interface with multiple methods. Use lambda expressions for single-method interfaces, like Runnable.

Are there any performance differences between them?

Yes, lambda expressions can be more memory efficient as they do not create a new class instance, while anonymous classes do.

Which one is more readable?

Lambda expressions are generally more readable due to their concise syntax, especially for simple operations.
