Need help with what is in bold. GUI application Design an appropriate GUI application to set up and run the proposed Geometric Shape that would allow a user to create any Geometric Objects and read a text file containing Geometric object details and print its area and perimeter. You may use the sample design as given in the Lab 02 Question 5. The GUI for this assignment should create at least two new classes one being the JFrame for displaying the GUI JPanel, and the GUI JPanel with its components. The GUI needs to be able to allow Calculation of area and perimeter of different Geometric Objects based on a user selection. User should be able to select different Geometric Object and based on the Object type, user is asked to input radius, width, length or sides etc. Then the GUI application calculates and display area and perimeter. Reading of Geometric Object information from a file as GeometricOjects.txt and printing out a report of all Geometric Objects information with area and perimeter. Your GUI application should also contain a button to read a file GeometricObjects.txt. The program should read each line, calculate area and perimeter of the object and display the information in TextArea. Your program must work for any data file in this format as given below, regardless of how many entries. Format of the data file should be as the following: Object Type, Data Example Circle, 6.0 Rectangle, 3.5, 4.5 Triangle, 2.3, 3,4, 4,2 My classes:

GeometricObject

public abstract class GeometricObject { protected String colour; protected boolean filledIn; // Construct a geometric object public GeometricObject(String colour, boolean filledIn) { this.colour = colour; this.filledIn = filledIn; } // Return colour public String getColour() { return colour; } // Set a new colour public void setColour(String colour) { this.colour = colour; } // Abstract method findArea public abstract double findArea(); // Abstract method findPerimeter() public abstract double findPerimeter(); public String toString() { return " Colour: " + colour + " and filled " + filledIn; }

}

Circle

public class Circle extends GeometricObject { private double radius; // Constructor public Circle(String colour, boolean filledIn, double radius) { super(colour, filledIn); this.radius = radius; } // Get and set methods for radius public double getRadius() { return radius; } public void setRadius(double radius) { this.radius = radius; } // Methods to calculate area and perimeter public double findArea() { return Math.PI * radius * radius; } public double findPerimeter() { return 2 * Math.PI * radius; } // toString method public String toString() { String toScreen; toScreen = super.toString() + "Radius of a circle is " + radius; return toScreen; } }

Rectangle

public class Rectangle extends GeometricObject

{ private double width; private double length; // Constructor public Rectangle(String colour, boolean filledIn, double width, double length) { super(colour, filledIn); this.width = width; this.length = length; } // Getters and setters public double getWidth() { return width; } public void setWidth(double width) { this.width = width; } public double getLength() { return length; } public void setLength(double length) { this.length = length; } // Calculate area and perimeter public double findArea() { return length * width; } public double findPerimeter() { return 2 * (length + width); } // Override parent toString method public String toString() { String toScreen; toScreen = super.toString() + "Width and length of a rectangle is " + width + " " + length + " respectively"; return toScreen; } }

EquilateralTriangle

public class EquilateralTriangle extends GeometricObject { private double side;

public EquilateralTriangle(String colour, boolean filledIn, double side) //Constructor { super(colour, filledIn); this.side = side; }

public double getSide() { return side; }

public void setSide(double side) { this.side = side; }

public double findArea() { return ( Math.sqrt(3) * side *side)/4; }

public double findPerimeter() { return 3 * side; }

public String toString() { return super.getColour() + "\t" + super.filledIn + "\t" + getSide(); } } //End Class

Cylinder

public class Cylinder extends GeometricObject { private double radius; private double height;

public Cylinder(String colour, boolean filledIn, double radius,double height) //Constructor { super(colour, filledIn); this.radius = radius; this.height = height; }

public double getRadius() { return radius; }

public void setRadius(double radius) { this.radius = radius; }

public double getHeight() { return height; }

public void setHeight(double height) { this.height = height; }

public double findArea() { return 2* Math.PI * radius *(height+ radius); }

public double findPerimeter() { return 2 * (2* Math.PI * radius+height); }

public String toString() { return super.getColour() + "\t" + super.filledIn + "\t" + getRadius()+ "\t" + getHeight(); } } //End Class
