Question

This is a question that I have and would like someone who has experiences with scene graphs and entity component systems to answer.For context, I am currently implementing a game engine and currently I am debating on our current design.Our current design is we have a singular game component class that every component inherits from. 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. A follow-up question that is part…

Explanation of Solution

Program:

File name: “Salesperson.java”

//Define a class named Salesperson

public class Salesperson

{

    //Declare the private variables

    private int id;

    private double sales;

    /Define a method Salesperson that includes

    an integer ID number and a double annual sales amount/

    Salesperson(int idNum, double amt)

    {

        //Assign the values

        id = idNum;

        sales = amt;

    }

    //Define a method to display the id
