Question

With the new one-parameter constructor that takes the size of the turtle, we can modify the instantiation of the turtles. In the Gui class in the edu.westga.cs1301.project1.view package. Do the following:

In the Gui constructor, for the instantiation of the first turtle replace the call to the DoodleTurtle default constructor with a call to the one-parameter constructor and pass in a size of 30.

Do the same for the second turtle but give it a size of 15.
public class Gui extends GraphicsProgram {

public static final int APPLICATION_WIDTH = 900;
public static final int APPLICATION_HEIGHT = 900;
private static final long serialVersionUID = 1L;

private DoodleController sketchPad;
private StatisticsController statsController;
private DoodleTurtle turtle1;
private DoodleTurtle turtle2;

/**
* Constructs and initializes the GUI.
*
* @precondition none
* @postcondition none
*/
public Gui() {
this.turtle1 = new DoodleTurtle();
this.turtle2 = new DoodleTurtle();
this.sketchPad = new DoodleController(this.turtle1, this.turtle2);
this.statsController = new StatisticsController(this.turtle1, this.turtle2);
}
