In C++ terms, a Java interface is a pure abstract class that only has member functions. No fields.

Fields on interfaces are always “constants”. (This is an older Java rule)

It is closer to the COM interface concept.

It could also be called an API contract.

An object can implement multiple interfaces.

This is an easy way to create delayed binding. The thread library was written decades ago, but you can create an Object today that will be usable by this old library as long as you honor the contract defined by the library. For Runnable, you must provide the run() method. The live Thread object will then invoke your run() method when you get your plumbing code correct.
