Creating a multi-user applicationApplication development in recent years has been moving heavily into multi-device collaborative software. Users want to be able to freely shift between their smartphones, laptops and desktops and to collaborate with friends and colleagues in real time. Needless to say, the applications themselves will have to reckon with multiple streams of information coming in at the same time and sort matters out accordingly. In this Discussion, you will consider how to construct a multi-user application with Java.

To prepare for this Discussion:Consider the following scenario: Assume you want to develop an application like Microsoft Word, Microsoft Excel, Microsoft Paint, etc. in which multiple users are allowed to access the same file simultaneously from different locations. All users can simultaneously read the file, but only one user is given an access to add, edit or delete data at a time.
To complete this Discussion:Discuss how you would use threading to accomplish the task described in the scenario mentioned.
