Circle Class
Write a Circle class that has the following fields:
- radius: a double
- PI: a final double initialized with the value 3.14159
The class should have the following methods:
- Constructor. Accepts the radius of the circle as an argument.
- Constructor. A no-arg constructor that sets the radi us field to 0.0.
- setRadius. A mutator method for the radius field.
- GetRadius. An accessor method for the radius field.
- area. Returns the area of the circle, which is calculated as
area = PI * radius * radius
- diameter. Returns the diameter of the circle, which is calculated as
diameter = radius * 2
- circumference. Returns the circumference of the circle, which is calculated as
circumference = 2 * PI * radius

Where we have components like SpriteRendererComponent, Mehs Component, etc. They inherit from this GameComponent class. The point of this is being able to have O(1) access to the scene to being able to modify components to attach more components with the idea of accessing those components to specific scene objects in a scene.Now, my question is what kinds of caveauts can this cause in terms of cache coherence? I am well aware that yes its O(1) and that is great but cache coherence is going to be really bad, but would like to know more explicit details and real-life examples such as write in RAM examples on how this is bad.

Also add a timer, which counts the elapsed time since the start of the game level.

And create a logic so that if the player loses his life (checkGame if the condition is false), then save this number together with his name into two variables. And display two buttons where one quits the game altogether (System.exit(0)) and the other restarts the game. public class GameGUI extends JPanel { private final Labyrinth labyrinth; private final Player player; private final Dragon dragon; private final ImageIcon playerIcon = new ImageIcon("data/images/player.png"); private final ImageIcon dragonIcon = new ImageIcon("data/images/dragon.png"); private final ImageIcon wallIcon = new ImageIcon("data/images/wall.png"); private final ImageIcon…arrow_forwardPlease original work Analyze the complexity issues of processing big data What are five complexities and talk about the reasons they make the implementation complex.
