Map<String, List<Integer>> map = new HashMap<>();
It waved a hand over a tangled mess of code:

" Chapter 1: The Diamond Operator Java 7 64-bit strode into the central data repository. Old Java 6 looked up from a stack trace. java 7 64 bits
It rewrote the logic:

In 47 minutes, the task was done.
And every time a modern Java program spins up a massive heap, processes a huge file, or uses a lambda on a collection, it sends a silent ACK back through the network to that old 64-bit giant. And every time a modern Java program spins
Java 7 64-bit retired to a quiet virtual machine in the cloud. It no longer ran production, but it was never deleted.
"Watch me," said Java 7.
