Java return intellityping?
 

You know how there are all kinds of typing shortcuts nowadays?

Let's say there's code like this:

m_socket.getOutputStream();

Is there some general way to get your editor (i.e. Eclipse) to create a variable of the correct type and assign it like so:

OutputStream outputStream = m_socket.getOutputStream();

I feel like this could save a lot of work.

You should not violate the Java Coding Conventions like this.

"General" and "i.e." are not consistent.

It looks like Eclipse Preferences / Java / Editor / Templates is the way to go.
Check your Eclipse documentation.

When I need this, I type some bogus type and the intended varname like this:
Foo outputStream = m_socket.getOutputStream();

Then, eclipse marks it as an error, and among the "Quick-fixes" there's one that
changes my bogus Foo to the actual return-type of the expression.

Yes. Mark the code. Then Refactor -> Extract local variable (Alt-Shift-L).

In Eclipse, use Quick Assist - Assign to local variable

Usually bound to Ctrl+2, L

In IntelliJ IDEA, you use "introduce variable" (command-ctrl-v), and it
will do exactly that.

I wouldn't be surprised if Eclipse had an equivalent hot-key.

You'd think with all that typing time saved, it would translate into
more thinking time.

In my depressing experience, it doesn't. Rather, below a certain
threshold, they appear to be congruent.

Typing team is not exclusive of thinking time.

That's probably the gist of the matter... :)

Often, most of my thinking is done before I start typing, whether it be
to use a shortcut or not. I find that although my available "thinking"
time may not be increased, the time-to-delivery is improved (decreased)
because of shortcuts. I can also use my knowledge that there *are*
short-cuts to allow my to defer thinking and decisions until a later
time. For example, I may be writing a class which might be better as two
classes, but it might not be. I know that I have refactoring tools, so
I'll start with the easiest to implement, and then consider refactoring
when it becomes relevant.
