How do I create an instance of a class in a method?

The Attempt at a Solution

I am a bit rusty whenever I think of instances. I always think of main method and objects when I see instance which gets me confused on what to do with the following example:

I have a abstract class, School, and inside School I have some methods that must preform some action on an instance. For example, there is a move() method that must move the instance of School. Another method named, personOld(), which returns whether or not an instance of School surpassed some determined age.
How do I create this instance?

Hm, in those examples they put the objects in the main method which is what I always think of when I see instance, but I have a class which isn't a main method which is what has gotten me confused.

Since my constructor, in my abstract School class, has many parameters then I must Constructor.newInstance()?

But how do I apply this?

You cannot instantiate an abstract class directly. You must first derive a concrete (i.e. non-abstract) subclass from it and then you can instantiate that.

You may want to give http://docs.oracle.com/javase/tutorial/java/IandI/abstract.html a visit.
