There are hundreds of examples of reading / writing files on the web - try google !

For example, a thread on this site a few weeks ago :

That's not a java-task - imho.

If the java program reads from System.in, and writes to System.out, a user may input the values by the keyboard, and gain feedback on the screen.

If he likes to use files for in- and/or output, he might do:

java Calculate < from.file > to.file

The input might be generated with another program, and the output formatted by a third one:

cat from.file | java Generator | java Calculator | java Formatter > toFile.html

Very flexibel.
