I don't understand variable instantiation.

I don't understand for example why we would do 

Toast allDoneToast = Toast.makeText(this,"All done!",Toast.LENGTH_LONG);

Vs just doing

Toast allDoneToast = new Toast();

Could anyone explain this type of variable instantiation where you don't say "new"?

Here's a note I found on: Toasts | Android Developers . It says, "Note: Do not use the public constructor for a Toast unless you are going to define the layout with setView(View). If you do not have a custom layout to use, you must use makeText(Context, int, int) to create the Toast."
