Comment Tricks

Miscellaneous Topics
#1

Does any else here do little tricks with java comments in order to save time switching between different behaviours?

For example, to toggle between two lines of code, just add/remove an asterisk:


// The space is there because otherwise the forum syntax highlighting detects it as a javadoc comment.
/* */int i = 0;
//*/int i = 1;



// The space is there because otherwise the forum syntax highlighting detects it as a javadoc comment.
/* /int i = 0;
//*/int i = 1;

Post your comment tricks here.

I would just normally change


int i = 0;

to


int i = 1;

It only requires changing a zero to a one (or vice versa)! :point:

#3

I’m using {Ctrl+/} or {Ctrl+7} in Eclipse to toggle each line separately.
I haven’t found a solution to invert the toggle on the two lines together,
from :

     int i = 0;
//   int i = 1;

to :

//   int i = 0;
     int i = 1;

The one I used was just an example.

Actual usage is for longer lines.

I think that most of us use “comment tricks” like this. When I need to disable the code for a moment (or test how good is the new version without deleting previous) I use comment/uncomment feature in NetBeans. :slight_smile:

You can conveniently toogle whole blocks by just adding a slash


		/*
			if(wanderChangeCounter<=0)
		{
			wanderChangeCounter=ran.nextInt(7);
			wanderX=ran.nextInt(3)-1;
			wanderY=ran.nextInt(3)-1;
			
		}
		  
		 //*/

to


	    //*
			if(wanderChangeCounter<=0)
		{
			wanderChangeCounter=ran.nextInt(7);
			wanderX=ran.nextInt(3)-1;
			wanderY=ran.nextInt(3)-1;
			
		}
		  
		 //*/

For comments, I just block select ant ctrl+shift+C (on eclipse)(Line comments on whole block)
For me hitting a whole line or block is easier than hitting one character.

#8

The only “trick” I use is to try and avoid block comments (/* … */) in favour of single-line comments (//)… Because then I can use the block comment to remove large chunks of code without a closing comment in between messing things up ::slight_smile:

I’m liking the tricks here, though.
