[英]How can I represent this regex in java?
我有这个正则表达式: [^\\w\\s+]
Regex101链接。
我试图在 java 中使用它来替换匹配的字符。 我意识到我需要转义括号和斜线,但它仍然没有按预期工作。
这是我到目前为止:
content = content.replaceAll("\\[^\\w\\s+\\]", "");
简短版本:不要转义括号。
精彩的在线工具https://regex101.com/可帮助您正确运行正则表达式。 如果您插入表达式并使用代码生成器(左侧边栏),它会为 Java 生成以下内容(以及一些使用正则表达式的代码):
final String regex = "[^\\w\\s+]";
你应该像那样使用正则表达式
