Hi buer, and welcome to Java Ranch.

1. When you post code, please UseCodeTags (←click). I've added them for you this time, but your indenting still isn't correct, so you might want to edit your post (just use the 'Edit' button, and before you save your changes, use the 'Preview' button to see if it looks OK).
2. I'm not quite sure what you want us to do. That's an awful lot of code.

The program will read data from a file named accounts.txt and then print information on what it found in the file.

Do you have a file accounts.txt? Does it contain data in the format that the program expects?

You also have much repeated code. I think you might do well to think of an abstract class to hold that repeated code.
