Question

我试图在整个文本文件中捕获包含某些4个字母前缀的所有单词。这些前缀被指定为名为“keywordList”的数组列表。代码当前的方式，我正在捕获所有需要捕获的单词（包含数组列表中的任何前缀“keywordList”），但是，我得到重复，并且由于某种原因，有时它会打印空白行（ s）打印出一个检测到的单词后。换句话说，打印输出的图案没有任何均匀性。

控制台输出：

Result: 
Result:APXP5558899
Result: 
Result: 
Result:IGC088838383833
Result: 
Result:CDAV
Result: 
Result:ASHGJHSGDSAGD

Result: 
Result:GHTS348939438
Result:EGLVxxxxxxxxxxxxx
Result:

我希望打印到这样的结果：

Result:APXP5558899
Result:IGC088838383833
Result:CDAV
Result:ASHGJHSGDSAGD
Result:MOE1477347384
