complete approach can be found in the blog of Martin Fowler, the author of refactoring. The use of basic techniques in eclipse can be referred to by anyone who can refactor to learn and practice.A complete refactoring process consists of:
Check out code from the version control system library
Read code (including test code)
Find Bad smell
Refactoring
Run all the unit Tests
Check in code to codebase
Let's combine git to give a more complete example.(vi) Practica
Transferred from the craftsman's treasure chest
I haven't followed the blogs of other netizens for a long time. Today, Shui mm gave the craftsman an almost impossible task. He chose 10 best blogs and recommended them to the homepage of the website. This task is really too difficult. I tried to find it one by one, and finally I had to make a fortune. It is estimated that this list is not satisfactory to the water mm (the

Ii. How to trigger the event mechanism when onmouseenter and onmouseleave are moving too fast
Description
If you want to move the mouse over the curve, you can not only highlight the curve, but also add a scissors icon at the mouse position. You can delete the curve when you press the scis
OnMouseLeave moving too fast leads to incorrect timing triggering event mechanisms
The diagram above illustrates
Want the mouse to move on the curve can not only highlight the curve, but also in the mouse position to add scissors icon, press the scissors can be deleted curve. The Mouseener and MouseLeave methods used directly on the curve, and then the mouse moves quickly on multiple curves, there are
unknown type, the second call determines the second unknown type. For multi-allocation, you must have a method that can be called to determine all types. Generally, you can set configuration items to generate more than one dynamic member function call using a member function call, so that more than one type can be determined in this process. To do this, you need more than one multi-state method call: each dispatch requires one call. The (polymorphism) methods in the following example are compet
StrategyNo matter what the program is, its purpose is to solve the problem. And in order to solve the problem, we need to write a specific algorithm. Using the strategy mode, you can replace the implementation part of the algorithm as a whole. The ability to replace the algorithm as a whole allows us to easily solve the same problem with different algorithms, which is the strategy pattern. (Overall substitution algorithm)Clarify responsibilities

code, because loosely coupled code can withstand changes.
Finally, writing code in the test-first mode forces you to observe your own code from the perspective of a user. By writing code in the test mode, you will be able to work from the developer's perspective that may use your code in the future. Since writing a test forces you to consider how another developer (maybe yourself in the future) uses your code, the code you finally write should be better designed.
