In a class, if you declare a method as static, you need not instantiate the class to be able to use the method. So , in your program, the method change() is being called directly by qualifying it with the class name.

You can read more in this [link](https://docs.oracle.com/javase/tutorial/java/javaOO/classvars.html).

What bala is saying,

because not only change(), but also college, are static, they are class methods/variables rather than instance (object) methods/variables.

That means "college" will be changed for the entire class, not just for a single instance (object).
