Teaching an Old Dawg New Tricks

Bob Koss — Thu, 21 Dec 2006 10:16:00 -0600

I learned something a few weeks ago that has saved me quite a bit of typing. I’m a pretty good typist but I still feel that saving a few seconds here and there pays compound interest when integrated over weeks, months, and a career. I’ve never seen anyone do this before and I get to work with a lot of programmers so I thought I’d share it here.

Joe “J.B.” Rainsberger was in our office a few weeks ago giving some internal training. Joe is the author of JUnit Recipes and if you don’t already own the book, buy two copies – it’s very good. Anyway, Joe was doing a demo for us and I watched how he created objects in Eclipse. If I wanted a new Counter object, for example, I would type:

Counter counter = new Counter();

But Joe would type:

new Counter();

and he then uses Eclipse’s Quick Help (ctrl-1) which offers to either create a local variable or a field in the class. That’s 2 keystrokes if Eclipse does it or 15 if I type it. That’s quite a return on investment in my book.

Try it and see if it makes you go just a little bit faster.
