Since I have an interface with two methods, how do I implement it with a concrete class? How do I write Lambda expressions for these two methods?
interface LambdaExpression {
void methodA();
void methodB();
}

4Your interface is not a [functional interface](http://www.baeldung.com/java-8-functional-interfaces) – Ousmane D. Jan 21 '18 at 16:59

@AndreyTyukin, please don't edit out proper grammar and/or punctuation. You've made this nearly unreadable. – ChiefTwoPencils Jan 21 '18 at 17:13

@ChiefTwoPencils Sorry, there was a race condition between the two edits, for some reason "the system" decided to take my (less elaborate) edit. I didn't even attempt to fix the grammar or add any punctuation in this one. Could one roll it back to your version somehow, I agree that your version made much more sense. – Andrey Tyukin Jan 21 '18 at 17:17

No worries @AndreyTyukin. I think you can roll yours back if you want. – ChiefTwoPencils Jan 21 '18 at 17:19

@ChiefTwoPencils ok, rolled back to your version, additionaly changed "Experession" to "Expression". [cleaning up the comment section] – Andrey Tyukin Jan 21 '18 at 17:30

You can not. Lambda expressions are for functional interfaces ie interface with only one abstract method.

@WaseemSaeed: create two interfaces with one abstract method each. – Anurag Sharma Jan 21 '18 at 17:44
