一行里是
1 3 -1
如果我要读到这个行的每个数，最方便的
操作是怎样。
还有，要输出到文本文件时如何规定格式之类的。
在c++ 里，俺一般用
sscanf，sprintf.
谢谢。 |

Read line, then use StringTokenizer.
You can use OutputStream.print() I think.

发帖数: 274 | 3 The way java does this is kind of complicated (actually
it is similar to c++ way with std io), you open a file
with an FileInputStream, then wrap the FileInputStream with
InputStreamReader to become a Reader, then wrap the
InputStreamReader to become a BufferedReader, then
use readLine(), finally parse out. Kao.

发帖数: 274 | 7 Actually I do appreciate the elegent (or elephant?) way of Java io
to read a file after couples of year java coding. But it does look
so stupid for first time user, hehe.
