assuming the following sentence: 假设以下句子：

this is @sys.any and. 这是@ sys.any和。 here @names hello. 在这里@names你好。 and good.bye 和good.bye

how would I find all the '.' 我怎么能找到所有的'。' besides the ones appearing in words that start with @? 除了以@开头的单词出现的那些？

2 个解决方案

(^|\\s)(\\w*(\\.))+ - this may satisfy the sample text you've posted. (^|\\s)(\\w*(\\.))+ - 这可能会满足您发布的示例文本。 You can find all '.' 你可以找到所有'。' in third group 在第三组

UPDATE: if in your text you have words, started with any other symbol, for instance, #asd.qwe.zxc , you can improve your reg exp: 更新：如果在你的文本中你有单词，从任何其他符号开始，例如#asd.qwe.zxc ，你可以改进你的reg exp：

(^|\\s)[^@]?(\\w*(\\.))+

The regex ^@|\\s\\w*(\\.)+ may be used to only find and match periods without @. 正则表达式^@|\\s\\w*(\\.)+可用于仅查找和匹配没有@的句点。
