Question

I am trying to print out the area of a rectangle using the following code

  System.out.println("Area of rectOne: " + rectOne.getArea());

however since the method getArea is defined in another class shouldn’t it be

  System.out.println("Area of rectOne: " + rectOne.NameOfClass.getArea()); 

Answer 1

This answer assumes rectOne is reference to instance of the class which has getArea() method.

getArea() is instance method, so, you need reference to instance of this class to access getArea() method.

Rectangle rectOne = new Rectangle(); //Here you are getting reference to Rectangle instance.
rectOne.getArea();
