IDEA  编辑器发现重复的代码在文件中，会提示黄色警告 found duplicated code in this file  finds duplicated code

具体如下图

这个警告不影响程序，但是看起来不太舒服

解决办法：

找到  Settings 、Editor 、 Inspections 、General、 Duplicated Code ，去掉后边的 √ 即可

This problem can be alleviat ed by detecting dupli cat ed code , extracting it into a separate new proc ed ure, and replacing all the clones (the instances of the dupli cat ed code ) by calls to the new proc ed ure. This paper describes the design and initial implementation of a tool that nds clones and displays them to the programmer. The novel aspect of our approach is the use of program dependence graphs (PDGs) and program slicing to nd isomorphic PDG subgraphs that represent clones. The key benets of this approach are that our tool can nd non-contiguous clones (clones whose components do not occur as contiguous text in the program), clones in which match- ing statements have been reorder ed , and clones that are intertwin ed with each other. Furthermore, the clones that are found are likely to be mean- ingful computations, and thus good candidates for extraction. Found dupli cat e code in 提示，因为项目中有重复的代码块。IntelliJ IDEA 默认会打开该提示。 在配置中搜索 dupli cat e code ，取消掉 Dupli cat ed code fragment后面的勾选 提示有重复代码块 3、解决方式 File → Settings → Ed itor → Inspections→搜索 “ Dupli cat ed Code ”→去掉 Dupli cat ed Code 后面的勾选→Aapply→OK
