.. You could also define a private void initWithDefaults() method and call it.



To my taste, I prefer to do all initializations in the constructor itself rather than delegating it all to private method. These are my personal beliefs:
  • To a fellow programmer reading your constructor, all initialization logic is present at one location.
  • If your constructor is getting too huge, it gets noticed at an early stage and raises a code smell that something may be wrong.
  • It makes the constructor logic highly cohesive, i.e. it only does the work of construction with no inclusion of other business logic

  • I am not against calling private methods in constructor, I am simply pointing out that delegating the construction work to a private method may not be good (at least as per my experience)

    Adding to what Campbell has posted, the sum of an arithmetic progression is

    n  x  ( (A1 + An) ÷ 2 )

    Where
    n is the total number of elements,
    A1 is the minimum
    An is the maximum

    Our progression has a common difference of 1, hence its easy to calculate n given the min and max :
    n = (An - A1) + 1

    I was curious to do this using Streams. My ugly solution:
    Maybe someone can find a better solution to help OP.

    Agreed, it's not that bad to push and revert with git.

    Disagree, while rebasing may simply allow the lines to accurately be transferred, functionally, the code has to be still tested. Changes will have to be made to make the rebased copy work. Conflict resolution is more than simply moving lines. Code functionality is equally important.

    Let's say we changed line X in a code within an if condition in Branch A now we simply want to move this to Branch B. A different branch can mean that the if condition itself no longer exists at that location or is refactored into some other method or the class itself does not exist or is renamed, or the package itself is deemed useless !! My personal experience is that refactoring is ugly with conflict resolution. From code point of view, a class name has changed, but from git's point of view, a file has been deleted and another file is added (unless there is an easier way that I do not know about).

    It's rude on my part to simply assume all have missed reading that. I am sorry about that.

    Let me share some software related mistakes :

    1. Before running a delete or update query, ensure that there is a 'where' clause and that you are running the complete query.
         (imagine running:  'delete * from employee' and promptly clicking commit instead of 'delete * from employee where employee_id=1000')
    2. Truncating the wrong table.
    3. The horrors of clicking 'push' in git and then remembering that you didn't test all scenarios.
    4. Working on the wrong branch.................. for weeks !!
