问题 My question: Should names of constant Java variables (within methods) be upper-case? I've always been under the impression that a) if a variable is never going to change, it should be declared final (to show/enforce that it won't change) b) it should be named in upper-case However, I've noticed in eclipse, when changing a variable (within a method) to be final/constant, and subsequently refactoring/renaming it to something like below: final int NODE_COUNT = 3; I get the following warning:

问题 I know there are a ton of how-to import Python modules not in path, but I have yet to come across using Python's __init.py__ vs sys.path.insert. Which method is better? Are there any obvious drawbacks to either, like performance? Is one more "Pythonic?" One scenario I can think of, is I have a program that users download and put in whatever directory, so I don't know the absolute path (unless I get it programatically). The folder structure is working dir __init__.py foo.py src/ my_utils.py _

问题 In JavaScript, it is possible to declare multiple variables like this: var variable1 = "Hello, World!"; var variable2 = "Testing..."; var variable3 = 42; ...or like this: var variable1 = "Hello, World!", variable2 = "Testing...", variable3 = 42; Is one method better/faster than the other? 回答1: The first way is easier to maintain. Each declaration is a single statement on a single line, so you can easily add, remove, and reorder the declarations. With the second way, it is annoying to remove

问题 Context I'm learning how to code in javascript consistently, readably and maintainably. I found nothing about the order of declaration of variables and functions. Example: var example = { A: function() { var a, b, c; }, B: function() { var a, b, c; }, C: function() { var a, b, c; } } Questions Alphabetically is the best one ? Is that the order can improve the speed of code execution ? 回答1: I use jslint to check the code quality. It can be integrated with Visual Studio and a lot of other stuff
