Now that the dust has settled on the launch of Java 8, we can begin to see the benefits that all these new features will bring to those of us willing to throw off the yoke of corporate oppression and start committing lambda expressions to a “Java 5” code base. The possibilities that lambdas bring, along with default methods, and the startling addition of static methods in interfaces are real game changers. For instance, it is now possible to write an entire Java application in a single interface! Those of us who have long railed against the tyranny of a single-class-per-file can now rejoice at being able to place all of our logic in a single file, and it doesn’t even need to be a class. As you will see from this post, the future is here and it is beautiful.
