application development

I am developing an application. How ca开发者_运维问答n I implement open and save operations? It would require connecting to the user's file system. Any sample code in this regard?

Still I can give you some guidelines.

1. You need to decide what technologies you want to use to build application like Java Swing or some other web related technologies.

2. If you are going for Java Swing then there are components which allow to save or open file with no interaction with file system. Please go through this FileChooser

I would advice you to have a look at Suns tutorial Reading, Writing, and Creating Files or alternatively java serialization.
