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

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

Some best practices include keeping lambdas short and focused, using method references when possible, and avoiding stateful lambdas.

Can you explain why keeping them short is important?

Short lambdas are easier to read and understand, which improves code maintainability and reduces the risk of errors.

What do you mean by stateful lambdas?

Stateful lambdas capture mutable state from their enclosing context, which can lead to unpredictable behavior and bugs.

How can I avoid using stateful lambdas?

You can avoid stateful lambdas by ensuring that they do not reference mutable variables from their enclosing scope.

Are there any performance considerations I should be aware of?

Yes, while lambdas can improve performance by enabling parallel processing, excessive use can lead to overhead, so use them judiciously.
