Explanation of Solution

Program purpose:

Prompt the age and name of the user and covert the name into uppercase then display the age and name.

Runtime errors:

The runtime error is commonly referred to as “bug”. It occurs during the execution of the program. It represents the logic or arithmetic errors.

Error #1:

Prompting string value from the user is in wrong format.

Correct statement:

//prompt the user to enter the string value

name = keyboard.next();

Error #2:

Converting the “name” text to upper case is in wrong format.

Correct statement:

//prompt the user to enter the string value

String result = name.toUpperCase();

Corrected code:

//include the required file

import java.util.Scanner;

//definition of "Input" function

public class Input

{

    //definition of main method

    public static void main(String[] args)

    {

        //create an object for scanner

        Scanner keyboard = new Scanner(System...

3. Problem Description: Define the Circle2D class that contains: Two double data fields named x and y that specify the center of the circle with get methods. • A data field radius with a get method. • A no-arg constructor that creates a default circle with (0, 0) for (x, y) and 1 for radius. • A constructor that creates a circle with the specified x, y, and radius. • A method getArea() that returns the area of the circle. • A method getPerimeter() that returns the perimeter of the circle. • • • A method contains(double x, double y) that returns true if the specified point (x, y) is inside this circle. See Figure (a). A method contains(Circle2D circle) that returns true if the specified circle is inside this circle. See Figure (b). A method overlaps (Circle2D circle) that returns true if the specified circle overlaps with this circle. See the figure below. р O со (a) (b) (c)< Figure (a) A point is inside the circle. (b) A circle is inside another circle. (c) A circle overlaps another…
1. Explain in detail with examples each of the following fundamental security design principles: economy of mechanism, fail-safe default, complete mediation, open design, separation of privilege, least privilege, least common mechanism, psychological acceptability, isolation, encapsulation, modularity, layering, and least astonishment.
Security in general means the protection of an asset. In the context of computer and network security, explore and explain what assets must be protected within an online university. What the threats are to the security of these assets, and what countermeasures are available to mitigate and protect the organization from such threats. For each of the assets you identify, assign an impact level (low, moderate, or high) for the loss of confidentiality, availability, and integrity. Justify your answers.
