Some of those ways come from just plain object initialisers. Which are amazing and sorely needed in Java.

That's why you get `new List<T> { };` Because it could be `new ComplexObject { <fileds and properties> }`.

Same for `new`.

Some come from type inference which Java also has.

That's why you can have `List<T> foo = new List<T>();` and `var foo = new List<T>();`

It's not really "7 ways to assign a new empty List<T>". It's "7 ways to create an object", and Java several of them, too.
