18,560 PointsHello everyone, When we create new object Is type of object and name of class to be the same?
PezDispenser dispenser = new PezDispenser();
Am I correct in statements below?
PezDispenser is type of object. dispenser is name of object. new means we are creating new object. and PezDispenser() is method which refer to class that we created and it's name should be the same with class.

872 Pointsyeah the class name specifies the object type for example the line of code: assume that there is a class named animal. PezDispenser dispenser = new PezDispenser()
so here PezDispenser specifies that dispenser is an object of type PezDispenser.
the function PezDispenser() has the same name as its class.

You can create many different constructor attributes in your PezDispenser class folder, and despenser object can use all of them.

18,560 PointsChristopher thanks for response. "The first PezDispenser is simply stating what type of object you are declaring" Exactly, but could we name type of object somehow differently?

11,054 PointsYes you can name it whatever you want. You could name it PezDispenser cuteCatz or PezDispenser funnyFrogz. Please note though, that when programming larger programs with many different classes it starts getting hard to keep track of the names you come up. It is generally easier to keep it close to the original name.

11,054 PointsI think I understand what you are trying to ask. I will tell you what is happening and see if this helps you.
so you have PezDispenser dispenser = new PezDispenser();
The first PezDispenser is simply stating what type of object you are declaring
the name dispenser is simply the name you are calling it. It could be whatever you wanted it to be but generally it is a good idea to keep it the same, and in line with whatever language you are using naming conventions.
when you use = new PezDispenser() you are initializing it in whatever scope of the method you are using. So you are giving the method you use this in access to the class PezDispenser.
I hope this makes sense.
