// 读一行数据，并标准输出至显示器 s = in.readLine();// readLine()方法运行时若发生I/O错误，将抛出IOException异常 while (s != null) { System.out.println("Read: " + s);--s = in.readLine();} 你是把循环体内的 s = in.readLine(); 去掉了吗？那当循环前读入的数据后， ...

Most comparable functions operate in a similar manner. As an instance, the fgets() function in the C library and f.readline() in Python both function in the same way. In terms of functionality, the Scanner operates similarly to the BufferedReader. However, there is a key distinction betwe...
