What are the best practices for using lambda expressions in Java?

When using lambda expressions in Java, it's important to keep them concise and readable. Avoid complex logic within a single lambda.

Can you give me an example of a concise lambda expression?

Sure! For instance, instead of using an anonymous class to implement a Comparator, you can use a lambda like this: Comparator<String> comp = (s1, s2) -> s1.compareTo(s2);.

What about performance considerations?

Lambda expressions can improve performance by reducing boilerplate code, but be cautious with capturing variables from the enclosing scope, as it may lead to unintended memory usage.

Are there any specific scenarios where I should avoid using lambdas?

Yes, avoid using lambdas for complex operations or when you need to maintain state across multiple invocations, as it can reduce clarity.
