Suppose you are developing a graphical application. Write the code to define the class Square. A square is a Graphicalobject. A Square has the following properties: (1)a Size, which is immutable (cannot be changed after construction), and (2) a Location. Use encapsulation when implementing the properties. Your class should have a constructor with both properties as arguments, and a simple toString method. You may assume that the Graphicalobject class has a no-argument constructor and that any other classes are defined as necessary. Suppose you are developing a graphical application.
