RunBase framework in D365 F&O - Basic Requirement

class CountryPopulationBatchJob extends RunBaseBatch
{
    public static void main(Args _args){
         CountryPopulationBatchJob countryPopulationBatchJob = new CountryPopulationBatchJob();
        
         if(countryPopulationBatchJob.prompt()){
                countryPopulationBatchJob.run();
        }
    }

    static client server ClassDescription description()
    {
        return "Country Population";
    }

    public void run(){
       super();
       Info("Rumman is running");  
    }

    public container pack()  {
        return ["a", "b"];
    }

    public boolean unpack(container _packedClass)
    {     
      return true;
    }

}

Output:

Rumman is running

Solve below assignment:

See my project structure:

---

Create a table like below:

---

Now see table output

---

Create a CSV file like below:

---

write a CountryPopulationBatchJob class like below:

  class CountryPopulationBatchJob extends RunBaseBatch

    DialogRunbase                               dialog;
