Millistele muutujatele pääsevad Java lambda-väljendid?

Lambda expressions have access to the following types of variables:

• Local environment variables: Only those local static, non-static, or instance variables that are final or effectively final.
• Method parameters: The parameters of the method in which the lambda expression is declared, if they are final or effectively final.
• Class fields: The fields of the current class (for non-static lambdas) and the static fields of the class.

A variable is considered effectively final if its value does not change after initialization.
