Question

Accepted Answer

Key concepts of Advanced Java and Java 8 include lambda expressions, streams, functional interfaces, and new features like default methods and static methods in interfaces.

Lambda expressions allow you to write more concise code by enabling functional programming in Java.
Streams provide a way to work with sequences of elements and perform operations such as filtering, mapping, and reducing.
Functional interfaces are interfaces with a single abstract method, which can be used with lambda expressions.
Java 8 introduced new features like default methods and static methods in interfaces to provide backward compatibility and enable interface evolution.
