Let Eclipse suggest variable names with control-space keystroke

I just learned that Eclipse can automatically create (or suggest) variable names for you. The suggestions are based on the class of the object you're about to create, and any characters you've typed for the variable name so far.

For example, if I'm in a method and I type Connection, followed by a space, then press the [Control][Space] keys, Eclipse adds a variable named connection, so my line changes to Connection connection.

Expand "sys" to "System.err.println" with control-space alvin November 28, 2007 - 10:36am

I've just recently started using Eclipse a lot, and I just typed System.err.println() one more time than I cared to. I just looked it up, and Eclipse also has templates, and one of the pre-built templates lets me type sys, then hit the [Ctrl][Spacebar] keystroke. This brings up a list of options I can choose from, one of those options being to insert the System.err.println() text in place of my sys text.
