Help this is confusing me

PezDispenser dispenser = new PezDispenser("Yoda");

class PezDispenser { final private String characterName;

public PezDispenser(String characterName) { this.characterName = characterName; }

public String getCharacterName(){ return characterName; }

}

So he made an object called dispenser using the class PezDispenser, and he used the new PezDispenser for the public PezDispenser(String characterName) { this.characterName = characterName;?

You're right up to "... and he used the new ...", but from there on I'm not quite sure what you're saying. The rest of that sentence appears to be a copy of the code for the constructor function.

Yeah what I said was kind of confusing, I was trying to say did he use the new PezDispenser he created for the public PezDispenser

I'm still not quite sure what you're asking. But the only object created is the one named "dispenser". The rest of the code you are referring to just defines the class.

okay can you explain this line of code for me? PezDispenser dispenser = new PezDispenser("Yoda"); please explain why he needed to write new PezDispenser("Yoda"), I don't understand what new PezDispenser mean.

You explained it yourself when you said "he made an object called dispenser using the class PezDispenser" — the "new PezDispenser" part means make a new object using the class "PezDispenser".
