Eclipse has a useful hotkey to assign current line to a local variable - when I type for instance:

Math.random()

and press ALT + SHIFT + L (Extract local variable), I can quickly change the line to 

double random = Math.random();

I would like to use the same trick for printing it to std out, so that the Math.random() is being changed to:

System.out.println(Math.random());

Currently the fastet way to to this is to type syso and use content assist to use a template, but that requires manual copy pasting. Anyone knows a better way to do this?

Two options come to my mind to achieve your goal, but both of them require the selection of statement first.

After you select statement, press CTRL+SPACE, then type syso and hit Enter. Selected statement will be placed inside System.out block:

System.out.println(statement);

Also you can prepare eclipse template (Window->Preference->Java->Editor->Content Assist->Templates), and give it some name:

System.out.println(${line_selection});${cursor}

After you select statement, press ALT+SHIFT+Z or select menu option Source->Surround With (also in context menu). Template you have created should be there so select it. Selected statement will be wrapped inside desired block of code.

As far as I am aware there is no shortcut available from the keys section of preferences. Is content assist really not fast enough for you in this case?

    Well, I'm just doing this out of curosity. There are some possible custom templates configurations - I wonder if the thing I would like to do is achievable at all. – dstronczak Jul 03 '13 at 07:16
