how to auto-increment line numbers in eclipse? - eclipse

eclipse (ganymede) is not incrementing the line numbers automatically. On creating a new class it prints line number till 6 (6th line contains closing bracket for class). After writing new lines in class, line number is still 6. To get the line numbers updated I again have to go to... show line number -> uncheck it -> apply -> check it again-> apply.
which setting will allow auto incrementation of line number?

How to format empty braces on same line (Eclipse formatter)

Where are the formatting settings in Eclipse to format an empty constructor like this
public ThisIsAConstructor() {} //this is supposed to be on one line
instead of
public ThisIsAConstructor() {
} //this is supposed to be on one line
I set everything in tab 'Brace positions' --> Same line. I am using the Google style guide (https://raw.githubusercontent.com/google/styleguide/gh-pages/eclipse-java-google-style.xml) with some custom adaptions.
Edit: I had some whitespaces in between, which prevented the expected formatting. If I have code like
public ThisIsAConstructor() {
} //this is supposed to be on one line
I have to format twice (one for removing the empty line via tab 'Blank Lines' an one for putting braces on one line. Is there a way to do that in one step?
There is an option to keep empty braces on the same line for most Java constructs, but unfortunately not for class constructors, as far as I could make out. If you haven't discovered it yet, here is how you get there:
In the Eclipse preferences, go to Java -> Code Style -> Formatter and click on Edit....
This should open a new window where you can edit your profile.
On the hand left side, go to New Lines -> Keep braced code on one line. Here you can find a couple of constructs. For each you can set a condition in which the braces should be on one line. Choose If empty respectively.

VSCode: order problems top to bottom rather than errors first, then warnings

I use the command: editor.action.marker.next and editor.action.marker.prev to move between errors in my code. However, instead of moving to the closest "problem", it moves to the "error" first and then the "warnings". I want to remove this ordering so that the commands move to closest "problem"
1 _ // -> cursor position
2 const package = require('package') // -> warning - missing semicolon
3 const badPackage require('bad-package // -> error
If I were to run marker.next in the above code with my cursor at line 1 I would jump to line 3, when I really would prefer to jump to line 2.
Is this possible in VSCode?
It is the default behaviour of coc.nvim which gives me hope.

vscode - for file type, make tab always just make 4 spaces

From my understanding, vscode's default tab behavior is to tab to the next column that is divisible by your tab length. So if my tab length is 4 and I am at column 1, it will add 3 spaces. Great!
For a certain file type, I would like to override this behavior and have tab always make exactly 4 spaces, rather than taking me to the next divisible column. How can I do this?
VScode currently spaces the cursor to column 5 from column 1. So it is adding 4 spaces to wherever you hit the tab key. I just typed a comment line like so
1234567890 and in the line under that I hit the tab key and the curson went to space 5 and space 9. So it appears to be doing what you want. I haven't set anything. In the settings file you can see the following description.
// The number of spaces a tab is equal to. This setting is overridden based on the file contents when editor.detectIndentation is on.
"editor.tabSize": 4,

What is the first line number in Eclipse?

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.
