[英]How can I represent this regex in java?
我有這個正則表達式: [^\\w\\s+]
Regex101鏈接。
我試圖在 java 中使用它來替換匹配的字符。 我意識到我需要轉義括號和斜線,但它仍然沒有按預期工作。
這是我到目前為止:
content = content.replaceAll("\\[^\\w\\s+\\]", "");
簡短版本:不要轉義括號。
精彩的在線工具https://regex101.com/可幫助您正確運行正則表達式。 如果您插入表達式並使用代碼生成器(左側邊欄),它會為 Java 生成以下內容(以及一些使用正則表達式的代碼):
final String regex = "[^\\w\\s+]";
你應該像那樣使用正則表達式
