Explanation of Solution

Given program:

RadioButton radio1 = new RadioButton("Option 1"); //Line 1

RadioButton radio2 = new RadioButton("Option 2"); //Line 2

ToggleGroup radioGroup = new ToggleGroup(); //Line 3

radioGroup.setToggleGroup(radio1); //Line 4

radioGroup.setToggleGroup(radio2); //Line 5

RadioButton:

  • User create a “RadioButton” control using the “RadioButton” class.
    • This class is present in the package of “javafx.scene.control”.
  • The controls “RadioButton” is used to permit the user to choose one option from the several possible options.
    • It may be selected or deselected.
  • Each “RadioButton” consist of a small circle.
    • If a circle appears filled-in, then the “RadioButton” is selected.
    • If a circle appears empty, then the “RadioButton” is deselected.

Example:

The example for “RadioButton” is shown below:

//create the radio button

RadioButton exampleButton = new RadioButton("Option 1");

ToggleGroup:

  • It is one class of JavaFX application which is used to create toggle group.
  • It is available in package “javafx.scene.control”.
  • Generally, the “RadioButton” controls are grouped together in a toggle group.
  • In a toggle group, only one of the “RadioButton” controls may be chosen at any time.
    • Then this “RadioButton” are referred as “mutually exclusive”.

Example:

The example for “ToggleGroup” is shown below:

// create a ToggleGroup.

ToggleGroup newToggleGroup = new ToggleGroup();

  • The above code is used to create a “ToggleGroup”.

Calling “RadioButton” in “ToggleGroup”:

The example for calling “RadioButton” in “ToggleGroup” is shown below:

//create the radio button 1...

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.

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.
