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.
•

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.

All classes must be created in Animal (5) First, start by building a class that describes an Animal at a Zoo. It should have one private instance variable for the name of the animal, and one for its hunger status (fed or hungry). Add methods for setting and getting the hunger satus variable, along with a getter for the name. Consider how these should be named for code clarity. For instance, using a method called hungry () to make the animal hungry could be used as a setter for the hunger field. The same logic could be applied to when it's being fed: public void feed () { this.fed = true; Furthermore, the getter for the fed variable could be named is Fed as it is more descriptive about what it answers when compared to get Fed. Keep this technique in mind for future class designs. Zoo (10) Now we have the animals designed and ready for building a little Zoo!

For context I am building a game engine, and want to implement physics simulation. There are a few approaches that I managed to find, but would like to know what are other approaches to doing physics simulation entry points from scenes, would you be able to visually draw me a few approaches (like 3 approaces)? When I say entry point to the actual physics simulation. An example of this is when the user presses the play button in the editor, it starts and initiates the physics system. Applying all of the global physics settings parameters that gets applied to that scene. Here is the use-case, I am looking for. If you have two scenes, and select scene 1. You press the play button. The physics simulation starts. When that physics simulation starts, you are also having to update the physics through some physics dedicated delta time because physics needs to happen faster update frequency.
