Java Double Brace Initialization of Lists and Sets Explained

Lots of Java developers need to seed a list for unit tests or proof of concepts. Which is why it's surprising that more people don't know about Java's double brace initialization feature. Double brace initialization in Java is relatively new, but it's not that new. And it lets you add items to a List or Set quickly, all right there in the constructor call, almost as if the list or set elements were method arguments. In this quick tutorial you'll see how Java double brace initialization works, and you'll no doubt be motivated to start using it in your own programs, POCs and unit tests. Happy Java!
