Using Objects: Referencing an Object's Fields

Referencing an Object's Fields

Object fields are accessed by their name.
You may use a simple name for a field within its own class.

System.out.println("Width and height are: " + width + ", " + height);

We can add a statement within the Rectangle class that prints the width and height.
Code that is outside the object's class must use an object reference or expression, followed by the dot (.) operator, followed by a simple field name.

ObjectReference.fieldName
