Lambda expressions were a big part of the Java 8 release. As a follow-up to that improvement, private methods in interfaces are now feasible. Previously, we could not share data between non-abstract methods of an interface. With Java 9, this data sharing is possible. Interface methods can now be private. Let's look at some sample code.
