Inheritance: Correct initialization to store values ​​in a HashMap

I am working with separate programs, one will read in a file .txt

, and then that same program will store the read values ​​in another program containing HashMap

. The program containing HashMap

is called Hero.java

and is abstract class

. I have a program that extends this program called Cop.java

. With this in mind, I would like to know the correct way to transfer files read from mine GameDriver.java

to HashMap

.

As far as I know, one way to do this is to initialize Cop.java

like,

Cop N = new Cop();

      

        
        
        
      

    

and then make a method call

N.rescue();

      

        
        
        
      

    

What's the correct way to add read values? Can I use a solution like this? I am trying to get String cn

to save to map name

and int pts

save to points

below. Thanks for all the answers and please let me know if you need any clarification. I'll post my GameDriver.java

code as well as my Hero.java

code Thank you!

GameDriver.java

import java.io.*;
import java.util.*;
import java.awt.*;

public class GameDriver {

  public static void main(String[] args) throws FileNotFoundException {

         Cop N = new Cop();
         String s;
         File f = new File (args[0]);
         Scanner input = new Scanner(f);
         while (input.hasNext()) {
                s = input.next();
                if (s.equalsIgnoreCase("h")) { Character c1 = new Cop();
                                                 System.out.println(c1); }

                if (s.equalsIgnoreCase("r")) { String cn = input.next(); //HashMap name
                                               int pts = input.nextInt(); //HashMap points
                                               N.rescue();}

         }

  }
}

      

        
        
        
      

    

Hero.java

import java.util.*;
import java.io.*;
import java.awt.*;

public abstract class Hero extends Character
{
   private String heroname1;
   public Hero() {
          heroname1 = "Rick Grimes"; //the default player name
   }
   HashMap name = new HashMap<String, GameDriver>();
   HashMap points = new HashMap<Integer, GameDriver>();

   public Hero(String newhero) {
          if (newhero.length() > 0) {
               heroname1 = newhero;
          } else { heroname1 = "Rick Grimes"; } //defaulted as protagonist
   }

   public String getHeroName() {
          return heroname1; //return the name
   }

   public String rescue() { //class to rescue people or things
          return heroname1 + " rescued " + name + " for " + points + "!";
   }

   public String toString() { //print
          return heroname1;

   }
}

      

        
        
        
      

    

common goal

I realize I didn't add to my overall goal: the goal is to read in a file to create a new hero (usually just one) and store multiple people / things in it in this hypothetical game. For example, if the file says

c h Rick Grimes //create hero
r Carl 100 //rescue for x amount of points

      

        
        
        
      

    

I want this data to be saved to a map or whatever and output like this:

Rick Grimes
Rick Grimes rescued Carl for 100 points!

      

        
        
        
      

    

also note that this should all be done via inheritance
