On: Java 8: Replace traditional for loops with IntStreams

[unwind]

For your example, sure.

But it's not uncommon (in my opinion) to write stuff like

    EnumMap<FooEnum, BarClass> map = new EnumMap<FooEnum, BarClass>(FooEnum.class);

which to me ought to read something like

    var map = new EnumMap<FooEnum, BarClass>();

Of course, I don't do a lot of Java programming these days and perhaps my first example is simply broken due to ignorance.

When I wrote something very similiar to that last week, I failed to figure out how to avoid repeating the type signature, and was annoyed.

It's not quite as short as you'd like, but since Java 7 came out in 2011, it's been possible to write:

  EnumMap<FooEnum, BarClass> map = new EnumMap<>(FooEnum.class);

using the "diamond operator" [1]. In fact, my IDE even provides automatic hints to make use of it!

With that said, I do think java has too much pro-long-method-and-variable-name culture.

You can already do something similar, instead you write

Map<SomeComplexTypes> map = new HashMap<>();
