You can use CodeMatch to write snippets that call methods and CodeMatch can also auto-import libraries (or insert the classes/methods inline).
Of course, this isn't featured in the video.
I don't program Java, but I might also be OK with having a program add type names where necessary. For example, you type "foo = new Foo()" and the software will add "Foo " in front, making the line "Foo foo = new Foo()". But, programming in terms of concrete instances is To Be Avoided, so maybe default to an interface and allow the programmer to toggle between the interfaces Foo implements. It would have to be a measurable win, though; typing FooI is not that hard, after all.
I'm definitely not discouraging the use of tools to make managing boilerplate easy; but it's a very fine line, some boilerplate cannot be eliminated with clever library use (imports), but some can (finding the path to the Desktop). Once you have a super-cool boilerplate generation tool, it becomes more tempting to add a quick snippet than to fix the language or library deficiency that's pushing you in the direction of too much typing.
Sometimes it's good to imagine things taken to the extreme. Imagine that C didn't have a preprocessor but it did have an editor that had really good snippets. Instead of saying #define PI 3.14 in your math.h file, the snippet would just type 3.14 in for you whenever you said "insert pi". This would produce the same object code as the preprocessor, but without another extra piece of machinery to mess up your source code. What you type is what the compiler sees!
Turns out that this isn't good, because computers are really good at pushing symbols around, but humans aren't. So don't show the humans the details, show them the abstract and let the compiler push symbols around.
(I've always wondered why someone doesn't add a preprocessor to Java. See also: coffeescript / javascript.)
If you're suggesting that the tool isn't useful or to be encouraged (as you seem to suggest in earlier posts), I'm interested in better understanding your rationale.
As far as I can tell, you have only critiqued possible ways that CodeMatch could be used, not CodeMatch itself.
