缓冲读取器读取文本直到字符 [英] Buffered Reader read text until character

问题描述

我正在使用缓冲的读取器来读取充满信息行的文件。一些较长的文本行扩展为多于一行，因此缓冲将其视为新行。每行以';'符号结尾。因此，我想知道是否有一种方法可以使缓冲的读取器读取一行直到到达’;’，然后将整个行作为字符串返回。

I am using a buffered reader to read in a file filled with lines of information. Some of the longer lines of text extend to be more than one line so the buffered views them as a new line. Each line ends with ';' symbol. So I was wondering if there was a way to make the buffered reader read a line until it reaches the ';' then return the whole line as a string. Here a how I am using the buffered reader so far.

  String currentLine;
        while((currentLine = reader.readLine()) != null) {
            // trim newline when comparing with lineToRemove
            String[] line = currentLine.split(" ");
            String fir = line[1];
            String las = line[2];
            for(int c = 0; c < players.size(); c++){
                if(players.get(c).getFirst().equals(fir) && players.get(c).getLast().equals(las) ){
                    System.out.println(fir + " " + las);
                    String text2 = currentLine.replaceAll("[.*?]", ".150");
                    writer.write(text2 + System.getProperty("line.separator"));
                }
            }
        }

推荐答案

使用 扫描器 ，您可以在其中设置定界符：

It would be much easier to do with a Scanner, where you can just set the delimiter:

Scanner scan = new Scanner(new File("/path/to/file.txt"));
scan.useDelimiter(Pattern.compile(";"));
while (scan.hasNext()) {
    String logicalLine = scan.next();
    // rest of your logic
}
