Hello, I am trying to take user input (customer info such as name, address, phone number , etc. from many text fields - use enter to go to next text field as they are set up in a grid layout). This is done in one class and when you click the "Save" button in the frame I want to write this information to a random access file. Do I do this in the same class or do I need to create a new class for this and, if so, how do I keep track of the user input from the frame in this new class? I also do not want to allow duplicate names to be entered. I know about DataInputStream and FileInputStream and System.in but am confused as to how I go about starting all of this and putting it all together?? Any help would be greatly appreciated as I am fairly new to Java!

"kiran1",
The Java Ranch has thousands of visitors every week, many with surprisingly similar names. To avoid confusion we have a naming convention, described at http://www.javaranch.com/name.jsp . We require names to have at least two words, separated by a space, and strongly recommend that you use your full real name. Please log in with a new name which meets the requirements.
Thanks.
