I am making a game, but to install it, it requires 7zip to unpack the files, so I have included the 7zip installer. I have created a JFrame with a JTextArea in it to input the 7zip icense, but I cant get BufferedReader to read the whole txt file (its 57 lines, and I think its mainly because Bufferedreader wasnt designed to read that many lines.) Can you please help me read the file so I can add the license into the game. Thanks, Jackson

EDIT I feel so loved when you guys pay out a newb for not knowing things -_-

Answer 1

我最近写了一个节目,读到与BufferedReader合用文档中的11亿条线。

阅读整个档案的最简单方式是使用57条字。

String text = FileUtils.readFileToString(new File("uncompressedfile.txt"));

或

String text = FileUtils.readFileToString(new File("uncompressedfile.txt"), "UTF-8");

或 if compressed with gzip (similarly with 7zip)

String text = IOUtils.toString(new GZipInputStream("compressedfile.txt.gz"));

Answer 2

仅读到档案中的完整案文。将其储存在<代码>String 可变中,然后将这一数值输入JTextArea,因为57条线并不大,可以储存在证书上。

Answer 3

您可以采取两种方式:

1>Using Scanner

void read() throws IOException {
    StringBuilder text = new StringBuilder();
    String NL = System.getProperty("line.separator");
    Scanner scanner = new Scanner(new FileInputStream(fFileName), fEncoding);
    try {
      while (scanner.hasNextLine()){
        text.append(scanner.nextLine() + NL);
      }
    }
    finally{
      scanner.close();
    }
    log("Text read in: " + text);
  }

2>

static public String getContents(File aFile) {

    StringBuilder contents = new StringBuilder();

    try {

      BufferedReader input =  new BufferedReader(new FileReader(aFile));
      try {

        while (( line = input.readLine()) != null){
          contents.append(line);
          contents.append(System.getProperty("line.separator"));
        }
      }
      finally {
        input.close();
      }
    }
    catch (IOException ex){
      ex.printStackTrace();
    }

    return contents.toString();
  }

57条线并不是说,巨大的缓冲器被用在纸浆中阅读档案:
