You're creating a new instance of the Treet class. It is called treet. To the left of the equals sign, you create a Treet sized hole in memory and label it treet so you can access it later. You then assign into that hole an actual instance of a Treet by using the equals sign, to the right of it create a Treet by using the keyword new then calling the constructor called Treet(). That makes an object/instance of the class.
So, you make a treet sized hole labelled treet, create an actual Treet instance and put that instance in the hole!
Make sense?
Steve.

Sorry for the slow response, I was out with friends for a beer.
The way I visualise this is that I create a memory hole with a label by declaring the variable name:
Treet treet;
That creates a hole in memory ready to be filled with an instance of a Treet. The hole has a label so we can reference it.
We next need to create an instance of the Treet class which we do by calling the constructor of the class. We assign that instance into the hole, filling it, and allowing us to access that instance with the label we created above.
Treet treet = new Treet();
So there's one hole and one hole-sized instance. We put the instance in the hole and access it using the label we crested for the hole.
I hope that helps. Do you understand constructors, instances, objects etc? I did a post about that somewhere. I'll post a link if it would help.
Steve.
