I don't want to have to download and install eclipse on this machine, but for you who do have it, what is the first line on the Eclipse IDE? On the left after you enable line numbers in the left hand column, the first number is?
In the Java source editor, at least, the first line number is 1.

In my older version of eclipse, I used to get the line number:column number at the status bar.
But when I upgraded to eclipse Juno, it is missing.
I am aware of the print margin settings but I want the column number to be displayed.
Is there a way out for enabling or displaying the line number : column number?
If I have a +20000 line source code in Eclipse, and I want to select say everything between line 400 and line 12000, how can I do that?
Other than selecting with mouse.
I currently work on Eclipse Juno 4.2 (but problem is connected with older versions of eclipse as well) and I found an irritating issue. When we try to create new class with a default formatter settings, eclipse put an empty line at the end of file.
I tried to figure out by myself how to remove this annoying line and search in formatter options. I found option that could help solve my problem but i found it's disable by default.
My question is: How to get rid of this line?
It's not really an empty line. It just appears that way in Eclipse.
When you see the blank line in Eclipse, it means that the last line of the file is terminated by a new line character. That is, the last characters in your Java file are probably }\n (on *nix, with LF line endings) or }\r\n (CRLF line endings on Windows), followed in each case by the end of the file.
You can prove this to yourself using tail or cat on *nix. If the prompt appears on the same line as the last line of code, then there's no trailing new line. If the prompt appears on a separate line, then there is a trailing new line character. If there's a blank line before the prompt, then there's an empty line in the file.
If the above doesn't convince you, use a hex editor. :o) An empty line would appear as two consecutive line endings: \n\n or \r\n\r\n (on *nix and windows respectively).
There's nothing wrong with the last line of your file having a new line character at the end. In fact, it's a good idea to leave it there, because some tools will warn if it's not there. These tools include Checkstyle (there's an Eclipse Checkstyle plugin) and diff.
Eclipse allows you to put the cursor there in case you want to add new content to the end of the file. (This isn't often needed in Java, because most people don't put more than one top-level type in a file.)
Best just to leave it there, and get used to Eclipse showing it.
I am writing a little bit of documentation and code explanation. I would like to copy code from eclipse including line numbers, so that it becomes easier to reference the code in the text.
Is there any way to do this in eclipse or some other IDE, editor?
Since Eclipse 3.4 and bug 19602, you will print the line numbers if you have activated them on the Eclipse editor.

Printing a source will give you:

You can do it by printing a PDF of source file, then copying source with line numbers from the PDF document.
It works for me with eclipse PDT + CutePDF, it should also work with Acrobat PDF printer
Another not-so-clean work-around to achieve this. This is specific to the Subversive plug-in.
3 steps to follow:
Delete the piece of code you need to copy and save the source file.
Right click the file and chose option Team -> Create Patch.. and save it to a file, say copy.patch
Undo (Ctrl + Z) the changes to revert the deletion done in step 1 and save the source file again.
Open the patch file and use the contents.
This also includes the file-name (if desired) along with the line number and retains the indentation.
In IDEA you had the possibility to put your cursor on all lines.
Is this possible in Eclipse?
Eclipse 3.5 should have a column mode (which is what I think you're asking about) - use Alt+Shift+A:

I haven't tried this since I'm stuck at version 3.4.1 for the time being. There's a patch that claims to work for 3.4.0 (http://tkilla.ch/column_mode/), but it's not working for my 3.4.1 install.
If you refer to the ability to select a group of lines (like a all function), you can use the outline view

From there, you can move/rearrange/delete all block of text.
If it is about column mode, see my answer here.
