bookChallenge: Static ID Generator

Task

Swipe to start coding

Design and implement a static class that serves as a simple unique ID generator. This class will be responsible for producing a new integer ID every time a specific method is called. The generated IDs should always start at 1, and each subsequent call should return an integer that is exactly one greater than the previous value. This ensures that all IDs are unique and sequential.

  • Define a static class named IdGenerator. This class should not be instantiated and should only contain static members.
  • Inside IdGenerator, declare a private static field that will keep track of the most recently generated ID. This field is essential for ensuring that each new ID is unique and increments properly.
  • Implement a static method named GetNextId. Each time this method is called, it should increment the private static field by 1 and return the new value. This guarantees that the IDs start at 1 and increase by 1 on each call.
  • The purpose of this static class is to provide a simple and reusable way to generate unique, sequential integer IDs for use in other parts of a program, such as assigning IDs to new objects or records.
