Can the label for a break have any name?

I am learning java after coming over from python. The book I am reading is currently discussing breaks, which I am familiar with. When it comes to labeled breaks, can I give the label any name I choose (barring keywords)? Another thing, how do I end the scope of the label?

Note: The book didn't really specify. I am assuming yes but if there are any rules and guidelines that are different from standard naming conventions please let me know.

You can label your loops and then use labeled breaks:

outer: for(int i = 0; i < 10; i++) {
  for(int j = 0; j < 10; j++) {
    System.out.println(i + "," + j);
    break outer;
  }
}

Output will be 0,0, since it breaks the outer loop on the first iteration of the inner loop.
