work with text files in java

Question

hi all. I have just started learning java after C + +. but so far nothing is clear. especially the work with classes.

tell me please how to open a file for reading or writing? it is desirable to provide the code completely.

Thanks. sorry for bad english.

upd: I started to learn java hour ago, but has not yet written a working program.

Thank you all for your answers!

Answer 1

Maybe you should read the IO part of the sun java tutorial first.

E.g. Reading, writing and creating Files

Answer 2

May the Apache Commons be your friend. There's a FileUtils class that does the job.

Answer 4

Here is a great set of tutorials for learning Java: The Java Tutorials.

For a tutorial on how to do I/O, look at the chapter Basic I/O from those tutorials.
