adding a method to android application
<p>I am fairly new in android and Java and this question might seem a little bit a naive question , 
I am trying to write a method called getDispalay() , this will be a public with no retuen.
I will print a message saying I am in the getDisplay method .
In java it is very simple , It will be called in main method , But I do not know how i can use main method in activity class ? I mean how can I write a method and call it as I need it ?
Thanks </p>
