What is the objective, goal, abstract, and purpose of Inertial lab in physics report. And what would be the conclusion.

I need an abstract on black, white, and gray hat hackers. please include any references

Assume you have created the following data definition class:

public abstract class Organization {
private String name;
   private int numEmployees;
   public static final double TAX_RATE = 0.01;

   public String getName() { return this.name; }
   public int getNumEmployees() { return this.numEmployees; }
    
   public abstract double calculateTax() {
      return this.numEmployees * TAX_RATE;
   }
}

In your own words, briefly (1-2 sentences) explain why the data definition class will not compile. Then, write modified code that addresses the issue.

Programming Language Concept assignment:

1. Design abstract data type for matrices with integer elements in C++ language, including operations for matrix addition, subtraction, and multiplication!
2. Design abstract queue data types for float elements in C++ language, including operations for enqueue, dequeue, and empty. The dequeue operation removes the element and returns its value!
3. Set semaphores in Ada and use them to provide co-operation and synchronization of competitions in shared buffer instances!

This is an abstract class to represent a weather sensor. Weather sensors

* the sensor state to damaged and needs to be fixed. A damaged sensor will
* throw an exception when trying to get its reading.
