java中的令牌解析 [英] token parsing in java

问题描述

我创建了一个带有printStream对象的文件，如下所示。

I have created a file with printStream object as shown below.

PrintStream outPutOffice = new PrintStream(
   new BufferedOutputStream(new FileOutputStream(inDir+"/Office.txt")));
outPutOffice.print(fValue + (findx < agtOffColCount ? "|" : ""));   

现在我必须阅读内容并用|分隔它们的标记因为我用|写了标记分离。我已经编写了如下所示的代码，它将正确读取行，但不能使用|单独标记字符。

Now I have to read it content and separate it tokens with "|" as I have written token with "|" separated. I have write code as shown below it will read line correctly but not separate token with "|" character.

BufferedReader inPutAgent = new BufferedReader(
   new InputStreamReader(new FileInputStream(inDir+"/Office.txt")));

String column=inPutAgent.readLine();
String []columnDetail = column.split("|");

columndetail数组在每个索引中包含单个字符，而我想在每个索引中使用单个标记。

columndetail array contains single character in each index instead i want single token in each index.

有什么问题？

推荐答案

split 方法适用于正则表达式并且由于管道符号（|）具有特殊含义并且是保留的，您需要像这样转义：

the split method works with regular expressions and since the pipe symbol (|) has a special meaning and is reserved, you need to escape it like this:

split("\\|");
