Java正則表達式用於$替換

Question

問題1
我正在嘗試將我的字符串從“（a）更改為（b）正確的行”更改為“（a）2（b）正確的行”。 為此，我正在使用此代碼，但它不能按我的要求工作

strtargetsentence=strtargetsentence_.replaceAll"([\(]([A-Za-z0-9])[\)][ ](to|and|or)[ ][\(]([A-Za-z0-9])[\)])","([\(]([A-Za-z0-9])[\)][ ](2|&|aur)[ ][\(]([A-Za-z0-9])[\)])"

同樣，我也想做這些組合

(a) to (b)--->(a) 2 (b)
(b) to (e)--->(b) & (e)  
(1) to (2)--->(1) aur (2)

問題2。
對於這些組合，Silimarly我也嘗試以下代碼

[a] we are going ---->[a] we are going
1)we are going---->1)we are going

strtargetsentence=strtargetsentence_.replaceAll("([\\[|\\(])?([0-9A-Za-z]+)([\\.|\\)|\\]?])", "$1$2$3");

Answer 1

我認為您應該寫幾個正則表達式替換。 對於問題1，可能會導致出現以下三個替換語句：

String strtargetsentence_ = "(a) to (b)";
String pattern1 = "(\\(\\w\\)) to (\\(\\w\\))";
String pattern2 = "(\\(\\w\\)) and (\\(\\w\\))";
String pattern3 = "(\\(\\w\\)) or (\\(\\w\\))";
String strtargetsentence=strtargetsentence_.replaceAll(pattern1,"$1 2 $2")
        .replaceAll(pattern2,"$1 & $2")
        .replaceAll(pattern3,"$1 aur $2");
System.out.println(strtargetsentence);

您的第二個問題的替代內容可能是：

String strtargetsentence=strtargetsentence_.replaceAll("(\\[?\\w)(\\]|\\))( ?.*)", "$1$2$3");
