Could you activate the speak() method without creating an object?

A good answer might be:

No.

Picture of the Program

The speak() method is part of an object. It only exists when there is an object for it to be part of (unlike a static method that does not need an object.) Here is a picture of the action, just as step 3 starts:

The variable anObject is a reference to the object that was created. That object contains the method speak(). So main() can find and activate speak() with: 

anObject.speak();

You might think that this is a needlessly complicated way to write a message on the monitor. And you would be correct. But remember that this is a simple example of object oriented programming. Later on, when the task gets really complicated, using objects greatly simplifies programming. Writing large programs in Java takes only one third to one fifth of the time it takes to write in other languages.
