File and PrintWriter objects
If I am using the File object to read a file and PrintWriter object to write to a separate file, can I use them under one method. Or is the File one method and the PrintWriter another method?

I don't think I understand your question: they are not methods, they are classes.Or is the File one method and the PrintWriter another method?
File (Java Platform SE 7 )
PrintWriter (Java Platform SE 7 )
Re: File and PrintWriter objects
Ok,
So I want to create a method to read data from a file. I also want to print data to a separate file. So, can I create one method to do both tasks using the File class and the PrintWriter class? I hope that makes more sense.
thank you
Re: File and PrintWriter objects
Your one method can call methods in other classes to do the reading and writing.can I create one method to do both tasks using the File class and the PrintWriter class?
BTW The File class does not have methods for reading the contents of a file.
The Scanner class has several methods for reading the contents of a file.
If you don't understand my answer, don't ignore it, ask a question.
Re: File and PrintWriter objects
Yes, you are right the File class will open the file. Got it. Thanks for the insight. I think I got it now.
thanks again
