1. Define the application callback Module
2. Define the application resource description file

The Resource Description file name must be the same as the application name and be suffixed with. app,
For example, bank. app
Then, place the resource description file in the path that erlang can search.

3. Start application

Application: start (bank ).

Compared with Exercise 1, before the application is started,
You do not need to call application: load/1 to load the application yourself.
Start the application monitor to check whether the application is started:

Appmon: start ().

If you already see the bank, the kernel is started by default.

4. Stop application

Application: stop (bank ).

5. Uninstall the application

Application: unload (bank ).
