Lambda: this inside a lambda refers to the enclosing instance

A lambda has no instance of its own, so this inside its body resolves to the object that was executing when the lambda was created, exactly as if the lambda's code were written inline.

Code

class Reporter {
    String name = "reporter";
    Runnable asLambda() {
        return () -> System.out.println("Lambda this.name: " + this.name);
    }
}
new Reporter().asLambda().run();

Output

Lambda this.name: reporter
