Cannot find symbol class

Question

I am having a "Cannot find symbol" problem. My Java is a bit rusty so I'm not exactly sure what it could be. I have two classes, City and SisterCities. The SisterCities references the City class. The City class compiles fine. Both classes are part of the same package. However, when I compile SisterCities, I get the error. Could you please tell me how to get the second class to recognize the first (import, extends, not really sure. I've tried alot) Here are those two classes so far...
****** City ********
package hw01;
public class City
     public final String name;
     public final String country;
     public final City [] sisters;
public City (String name, String country)
          // throw new RuntimeException ("Not implemented yet.");
          this.name = name;
          this.country = country;
          this.sisters = new City [0];
public City (String name, String country, City [] sisters)
          // throw new RuntimeException ("Not implemented yet.");
          this.name = name;
          this.country = country;
          this.sisters = new City [sisters.length];
          for (int i = 0; i < sisters.length; i++) {
               this.sisters[i] = sisters;
public void setSisters (City [] sisters)
          // throw new RuntimeException ("Not implemented yet.");
          for (int i = 0; i < sisters.length; i++) {
               this.sisters[i] = sisters[i];
public String getName ()
          // throw new RuntimeException ("Not implemented yet.");
          return this.name;
public String getCountry ()
          // throw new RuntimeException ("Not implemented yet.");
          return this.country;
public City [] getSisters ()
          // throw new RuntimeException ("Not implemented yet.");
          return this.sisters;
******** SisterCities *********
package hw01;
import java.util.LinkedList;
public class SisterCities
     public final LinkedList cityList;
public SisterCities ()
          // throw new RuntimeException ("Not implemented yet.");
public void addCity (City city)
          // throw new RuntimeException ("Not implemented yet.");
          this.cityList.add(city);
public int getNumCities ()
          // throw new RuntimeException ("Not implemented yet.");
public City getCity (int i)
          // throw new RuntimeException ("Not implemented yet.");

Answer 1

final attribute members like "cityList" must be initialised when they're declared or inside the constructors
if you want to compile, you'll also have to uncomment the "throws" in your methods (or return a value)
(pay attention to the error messages the compiler gives you and paste them all when posting questions)
