I have often observed that Java is great because it solves organizational problems. Strong and static types, interfaces and most of all, javadoc, were miraculous for conveying intent to integrators and maintainers. Even seemingly insignificant things like a naming convention for packages was extremely useful. A lot of the features trumpeted in Java when it was new, like abstract classes or checked exceptions, were adopted religiously at first but fell out of favor a long time ago. Interfaces and interface inheritance is extremely useful.
