A method inside a method?

Hello, I have this doubt in the "Incrementing and Decrementing" chapter of Java Objects:

public boolean dispense() {

boolean wasDispensed = false;
if (!isEmpty()) {
  pezCount-- ;
  wasDispensed = true;

}
return wasDispensed;

}

  • In the code above, the isEmpty() method doesn't have an object calling for it... Can someone explain how does it work? Regards.

isEmpty() is just a method invocation. You use dot notation when the method is on an object or a class (eg. object.doSomething() or Class.doSomethingStatic()). However, if the method is being called on the current object, then you can just call it.
