替换所有方法抛出PatternSyntaxException [英] Replace all method throws PatternSyntaxException

问题描述

查看以下代码：

String comment = "1)FCR pick up in Hong Kong2)Local charges will be paiy in Hong Kong & in HK$.3)Booking:[e-mail]4)FCR&DOC:[e-mail]:00852-23021977Fax:[phone]Transaction865320submittedVirginiaWong(T1281954U005) and Status is INCMP  on 10-JUN-11 11.28.45.764386 PM -05:00";
        //comment = comment.replaceAll("\\)", "\\\\)");
        //comment = comment.replaceAll("\\(", "\\\\(");
          if(comment == null || comment.length() < 100)
          {
            System.out.println();  
          }
         String[] strArray =    comment.split(" ");
         for (int i = 0; i < strArray.length; i++) 
           { 
              if(strArray[i].length() > 100)
               {
                 int iter = strArray[i].length() / 100 ;
                 int count = 100 ;
                 int initCount = 0 ;
                 String strReplace = null;

                    for(int j =0 ; j< iter ; j++)
                    {
                      strReplace = strArray[i].substring(initCount ,count); 

                      String strToReplace =  strReplace + "\n" ;
                      comment = comment.replaceAll(strReplace,strToReplace);
                      //comment = comment.replaceAll("\\)", "\\\\)");
                      //comment = comment.replaceAll("\\(", "\\\\(");
                      //comment = comment.replaceAll("\\\\", "");
                      System.out.println(comment);
                      System.out.println(comment.contains("\n"));   
                      initCount = count; //+1 ; 
                      count = count +100 ;
                    } 

                }   

            }
    }

当我跑步时，我得到以下异常：

When I run I get the following exception:

线程中的异常mainjava.util.regex.PatternSyntaxException：无法匹配的结束'）'
附近索引4
HK $ .3）预订：[e-mail]4）FCR& DOC：[e-mail]电话：00852-
23021977传真：00852-2

Exception in thread "main" java.util.regex.PatternSyntaxException: Unmatched closing ')'
near index 4 HK$.3)Booking:[e-mail]4)FCR&DOC:[e-mail]:00852-
23021977Fax:00852-2

根据我的理解，我必须逃避parantheses'（'，'）'，
I tr为了做到这一点（看看代码中的注释部分）没有任何异常，但我附加到字符串的换行似乎没有出现。

From my understanding I have to escape the parantheses'(',')', I tried to do this(look at the commented part in the code)there was nt any exception but the newline I am appending to the string doesn't seem to appear.

推荐答案

String.replaceAll 使用正则表达式作为第一个参数，以及）等字符在被解释为正则表达式时具有特殊含义。

String.replaceAll usess regular expressions for the first argument, and characters such as ) have special meaning when interpreted as regular expressions.

尝试 String.replace 。 （它仍然替换给定子字符串的所有出现。）
