把换行符替换成空字符串就行了吧。

    BufferedReader br = new BufferedReader(new FileReader(""));
    String line = null;
    int index = 0;
    StringBuilder sb = new StringBuilder();
    while ((line = br.readLine()) != null)
    {
        index++;
        sb.append(line).append("\r\n");
        if (index % 4 == 0)
        {
            System.out.println(sb.toString());
            sb = new StringBuilder();
        }
    }
