readme.txt The two files in this directory illustrate the three types of methods one can have in a Java 8 interface: - a "legacy" abstract method (the only kind you could have before Java 8 came along) - a static method - a default method The first of these (abstract) cannot be implemented in the interface itself, but must be implemented in any class that implements the interface. The last two (static and default) will have full implementations right in the interface, but these may be overridden in any class that implements the interface if the supplied method definition is unsuitable. The subdirectory in this directory has its own readme.txt.
