Question

Hello this is study question form my study guide for my Programing Midterm.

We have been using Eclipse this whole semester and I would need to fill in the red parts of the missing code.

Could someone help me with this so I could use this to study? Thank you so very much !!!

Design and implement a class called CircleTromSimpleGeometricObject that is derived from the SimpleGeometricObject given below. Store values in the CircleFromSimpleGeometricObject that represents the datafield and add a method that compute perimeter.

Explanation / Answer

ToDo 1

{ //forgot the curly braces

private String color="White";

private boolean filled;

ToDo2

public CircleFromSimpleGeometricObject(){

//Default Constructor

//You can Create object of this class in main() method

this.radius=0.0;

this.color="White";

this.filled=false;

}

Todo 3

this.radius=radius;

Todo 4 to Todo 6

super(color,filled); //invokes the parametrized constructor of parent class

this.radius=radius;

this.color=color;

this.filled=filled;

Todo 7

return ths.radius;

Todo 8

this.radius=radius;

Todo 9

return Math.PI()*this.radius*this.radius;

Todo 10

return 2*this.radius;

Todo 11

return 2*Math.PI*this.radius;
