extract method from duplicate code

消除代码重复：提取方法的应用
Duplicate code refers to ctions of code that are ud multiple times, sometimes in different locations or contexts within the same program. Extracting methods from duplicate code entails taking ctions of code that are similar and combining them into a single method, which is called from the various locations throughout the program. Extracting methods from duplicate code can help reduce code complexity, save development time, improve code readability, make programs more maintainable, and even add flexibility. In this article, I’ll explain the technique of extracting methods from duplicate code.

##1. Identifying Duplicate Code
The first step in extracting methods from duplicate code is to identify ctions of the codeba which are ud multiple times. It’s important to pay attention to code that are similar but not exactly the same; if two pieces of code contain nearly identical logic, then they can still be considered duplicate code.
It’s also important to pay attention to how the code is ud; if two pieces of code do the same thing, but are ud in different contexts, then they may require parate methods. Finally, it’s important to ensure that code is extracted in a way that does not introduce bugs into the program.
##2. Extracting the Method另外英语
尖头蚂蚱Once you’ve identified a ction of code that can be extracted, move it into its own method. The method should have a clear name that describes what it does, and should be broken down into small, readable chunks.

It’s important to ensure that all of the variables ud in the code are either pasd as parameters to the method, or are declared as global variables and updated by the method. Global variables should be ud with caution; if a variable is declared globally, then it should be declared in one place, and all references to that variable should be updated when the method is called.

After the method has been extracted, all references to the code need to be updated with calls to the new method. This requires careful attention to detail; if any references to the moved code are misd, then the program may not behave as expected.
It’s also important to consider how the program logic can be refactored; if the moved code was part of a loop, then it may be necessary to return statements or break statements. This step of the process should be carefully tested to ensure that the program behaves as expected.
##4. Testing and Refining
Once the new method has been extracted and the code has been refactored, it’s important to test the program to ensure that it behaves as expected. This involves running the program, paying attention to any changes in the program’s behavior, and debugging any issues that ari.
It’s also important to pay attention to the readability and maintainability of the code; if the 公公的幻想
method is too complex, or contains too much logic, then it may need to be broken down into smaller methods. Once the code has been tested and refined, the process of extracting methods from duplicate code should be complete.
##Conclusion
Extracting methods from duplicate code is an important step in writing maintainable and readable code. By identifying ctions of code that are ud multiple times, extracting them into methods, refactoring the code to call the methods, and testing and refining the program, developers can increa the maintainability and readability of their programs.
