BufferedReader.readLine()等待来自控制台的输入

Question

我试图从控制台读取文本行.线数预先不知道.BufferedReader.readLine()方法读取一行但在最后一行之后它等待来自控制台的输入.应该怎么做才能避免这种情况？

请参阅下面的代码段:

    public static String[] getLinesFromConsole() {
    String strLine = "";
    try {
        // Get the object of DataInputStream
        InputStreamReader isr = new InputStreamReader(System.in);
        BufferedReader br = new BufferedReader(isr);
        String line = "";
        while ((line = br.readLine()) != null)
            strLine += line + "~"; //edited

        isr.close();
    } catch (IOException ioe) {
        ioe.printStackTrace();
    }
    return strLine.split("~");
}

下面的代码可能会修复，将文本替换exit为您要求的特定字符串

  public static String[] getLinesFromConsole() {
    String strLine = "";
    try {
        // Get the object of DataInputStream
        InputStreamReader isr = new InputStreamReader(System.in);
        BufferedReader br = new BufferedReader(isr);
        String line = "";
        while ((line = br.readLine()) != null && !line.equals("exit") )
            strLine += br.readLine() + "~";

        isr.close();
    } catch (IOException ioe) {
        ioe.printStackTrace();
    }
    return strLine.split("~");
}
