java - 如何将一个文本文件分成两部分？

Question

我正在读取一个文本文件以使用Scanner 解析数据。该模式并不唯一，而且会重复，因此难以解析。我想将文本文件拆分为与原始文件相同位置的第二部分。第二个文件应从特定字符串开始。这样我就可以在使用扫描仪时指向不同的文件。

filePath = Paths.get(fileLocation);
Scanner scan = new Scanner(filePath);

文本文件内容如下所示

Initial data  xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx
xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx
xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx
xxxxxxxxxx Inputs xxxxxxxxxxxxxxxxxxxxxxxxxxx
xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx
xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx
xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx
xxxxxxxxxx Outputs xxxxxxxxxxxxxxxxxxxxxxxxxx
xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx
xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx
xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx

我想将从输出开始的数据放入第二个文本文件中

Answer 1

        //br is the bufferedreader
    String line=null;
        boolean outputflag=false;
        while((line=br.readLine())!=null){
        if(line.contains("Outputs")) {

        outputflag=true;
//if you do not want the word Outputs in the output file just add 7 to start index
line=line.substring(line.indexOf("Outputs"),line.length());
//write line to outputs file
        }

        if(outputflag) {
        //write line to ouputfile
        }
        }
