java的輸入問題

用 file
e.g. you have a file named "abc.txt"

then you can do: java xxx < abc.txt

then use the readline() again to get the information (didn't try in dos, it works in shell for sure)

you can also do: cat abc.txt | java xxx
which use readline() also. (doesn't work in dos for sure, use unix shell...)

assume you have data inside the file...of course...
