The Questions Are of a Organization of Programming course.

A variable can be characterized by a collection of attributes. What is one such attribute? The response is Implicit heap-dynamic allocation. Why is the response that?

Does static type binding require the programmer to specify the type of the variable in the program? Please Explain the answer and why it is the answer.

A certain variable is assigned a value. At that time, new storage is allocated for that variable to fit the new value. What kind of allocation was most likely used? Please provide an answer and please explain why the answer is the answer.

In this assignment, students should create five Java classes called Point, Circle, Square, Rectangle, and TestAll, as well as a Java interface called FigureGeometry. The TestAll class should implement the main method which tests all of the other files created in the assignment. After the assignment has been completed, all six files should be submitted for grading into the Dropbox for Assignment 3, which can be found in the Dropbox menu on the course website. Students should note that only the *.java file for each class /interface needs to be submitted; No *.class files need to be submitted into the Dropbox. Please see below specific requirements for the files that must be created and submitted:

Point.java Description:

The Point class should be declared as a public class and should meet all the requirements listed below. Its purpose is to store the Point (width and height) of a two-dimensional, rectangular geometric figure.

Instance Variables:

private int width;//stores the width of a Point object private

private int height;//stores the height of a Point object

Constructor: Point()

Parameters:

int theWidth,

int theHeight

Purpose: initializes the width and height of a Point object in the following manner:

width = theWidth;

height = theHeight;

Methods:

public int getWidth(){//returns the width of a Point object in the following manner

return width;}

public int getHeight(){//returns the height of a Point object in the following manner:

return height;}

public void setWidth(int theWidth){//assigns the width of a Point object as follows:

width = theWidth;}

public void setHeight(int theHeight{//assigns the height of a Point object as follows:

height = theHeight;

}

FigureGeometry.java Description:

The FigureGeometry interface should be declared as a public interface and should meet all the requirements listed below. Its purpose is to declare all the necessary methods that any geometric figure, such as a circle, rectangle, or square, should contain. The FigureGeometry interface should also declare a numeric constant, called PI, which can be used by classes that implement the FigureGeometry interface. Remember that method declarations in an interface should not include modifiers such as public, static, or abstract.

Declaring a method within an interface as static is illegal and will cause a compilation error. Additionally, the declaration of interface methods using public or abstract modifiers is redundant, and soon such declarations will be deprecated. Students should also note that the inclusion of instance variables within an interface declaration is not allowed; only static constants may be defined within an interface declaration, and the use of the static modifier on constants is also redundant. Basically, students should remember one general rule of thumb concerning interface declarations: Only one modifier should be used in an interface declaration--final should be used to declare constants.

public interface FigureGeometry{final float PI = 3.14f;

//Classes that implement the FigureGeometry interface MUST override this method which should return the geometric area of a figure:

//In an interface, methods are always public and abstract. Using these unnecessary modifiers is redundant, and future versions of

//Java may not support them.

float getArea ();

//Classes that implement the FigureGeometry interface MUST also override this method which should return the geometric perimeter of a //figure:

float getPerimeter ();}

Circle.java Description:

The Circle class should be declared as a public class that implements the FigureGeometry interface described above. Its purpose is to store the radius of a circular figure and provide the methods necessary to calculate the area and perimeter of such a figure.

Instance Variables:

private float radius;//stores the radius of a Circle object

Constructor: Circle()

Parameters:

float theRadius;

Purpose:initializes the radius of a Circle in the following manner:

radius = theRadius;

Methods:

1-public float getRadius(){//returns the radius of a Circle object as follows:

return radius;

}

2-public float getArea(){//returns the area of a Circle object as follows:

return getRadius() * getRadius() * PI;

3-public float getPerimeter(){//returns the perimeter of a Circle object as follows:

return getRadius() * 2 * PI;

}

4-public void setRadius(float theRadius){//assigns the radius of a Circle object as follows:

radius = theRadius;

}

The following coding example illustrates a version of the Circle class:

public class Circle implements FigureGeometry{//Stores the radius of this figure:

private float radius;

//Returns the radius of this figure:

public float getRadius (){return radius;}

//Returns the area of this figure:

public float getArea (){

return getRadius() * getRadius() * PI;}

//Returns the perimeter of this figure:

public float getPerimeter (){ return getRadius() * 2 * PI;}

//Assigns the radius of this figure:

public void setRadius (float theRadius){radius = theRadius;

}

}

Square.java Description:

The Square class should be declared as a public class that implements the FigureGeometry interface and should meet all the requirements listed below. Its purpose is to store the Point of a square figure (using the Point class described above and provide the methods necessary to calculate the area and perimeter of such a figure.

Instance Variables:

private Point point; //stores the Point of a Square object

Constructor: Square()

return point.getWidth();}

2-public float getArea(){//returns the area of a Square object as follows:

return getSideLength() *getSideLength();}

3-public float getPerimeter(){//returns the perimeter of a Square object as follows:

return getSideLength() * 4;}

4-public void setPoint(Point p){//assigns the point of a Square object as follows:

point= p;}

Rectangle.java Description:

The Rectangle class should be declared as a public class that implements the FigureGeometry interface described above. Its purpose is to store the Point of a rectangular figure (using the Point class described above) and provide the methods necessary to calculate the area and perimeter of such a figure.

Instructions

Write a program that prompts the user to enter 50 integers and stores them in an array. The program then determines and outputs which numbers in the array are sum of two other array elements. If an array element is the sum of two other array elements, then for this array element, the program should output all such pairs separated by a ';'.

An example of the program is shown below:

list[0] = 15 is the sum of: 
----------------------
list[1] = 25 is the sum of: list[5], list[14]; list[13], list[47]; list[46], list[47]; 
----------------------
list[2] = 23 is the sum of: list[0], list[33]; 
----------------------
list[3] = 65 is the sum of: list[4], list[32]; list[13], list[20]; list[20], list[46]; list[21], list[34]; list[32], list[38]; 
----------------------
list[4] = 34 is the sum of: list[0], list[14]; list[6], list[48]; 
----------------------
list[5] = 6 is the sum of: 
...

If no two elements can equal the value of an element, the line can remain empty, as shown above for list[0] and list[5].

1. Suppose a department has determined that some users have gained unauthorized access to the computing system. Managers fear the intruders might intercept or even modify sensitive data on the system. Cost to reconstruct correct data is expected to be $2,000,000 with 5% likelihood per year.

One approach to addressing this problem is to install a more secure data access control problem. The cost of access control software is is $50,000 with 80% effectiveness. Here is the summary of risk and control:

• Cost to reconstruct correct data = $2,000,000 with 5% likelihood per year
• Effectiveness of access control software: 80%
• Cost of access control software: $50,000

Determine the expected annual costs due to loss and controls. Also, determine whether the costs outweigh the benefits of preventing or mitigating the risks. (5 points)

1. Suppose the following:
   • James’ public key = K_j, James’ private key = K_j^-1
   • Randy’s public key = K_r, Randy’s private key = K_r^-1
   • Each person’s public key is known to others; Each one’s private key is only known to the owner

1. Explain how Randy can send a plaintext P to James secretly

2. Explain how James can verify if a plaintext P is sent from Randy

3. Explain how Randy can verify if a plaintext P is sent from James and at the same time P is sent secretly from James to Randy.
