Java IO Error, not sure why.

Question

Okay, these three classes are.. well.. basically non-existant, so I feel no reservations at posting them here. Please, someone, have a look and tell me why I'm getting an error in the child class. I'll post more further down.
CLASS ONE
import cs1.Keyboard;
public class CharCreate
     public CharCreate(String cN, String pN, String cP, String cT)
          if (cT.equalsIgnoreCase("foot soldier")==true)
               FSoldier dude = new FSoldier(cN,pN,cP);
          else if (cT.equalsIgnoreCase("heavy gunner")==true)
               HGunner dude = new HGunner(cN,pN,cP);
          else if (cT.equalsIgnoreCase("cavalry")==true)
               Cavalry dude = new Cavalry(cN,pN,cP);
          else if (cT.equalsIgnoreCase("medic")==true)
               Medic dude = new Medic(cN,pN,cP);
          else if (cT.equalsIgnoreCase("officer")==true)
               Officer dude = new Officer(cN,pN,cP);
          else if (cT.equalsIgnoreCase("engineer")==true)
               Engy dude = new Engy(cN,pN,cP);
          else if (cT.equalsIgnoreCase("special operations")==true)
               SOperations dude = new SOperations(cN,pN,cP);
     public static void newCharMaker()
          System.out.print("You have chosen to make a new character. Is that correct? (y/n) ");
          String keepGoing = Keyboard.readString();
          if (keepGoing.equalsIgnoreCase("y")==true)
               System.out.println();
               System.out.println("Welcome to the character creation process.");
               System.out.print("Character name? ");
               String cName = Keyboard.readString();
               System.out.print("Your name? ");
               String pName = Keyboard.readString();
               System.out.println();
               System.out.print("Password? ");
               String cPassword = Keyboard.readString();
               System.out.print("Re-enter password? ");
               String tempPassword = Keyboard.readString();
               System.out.println();
               while (cPassword.equals(tempPassword)!=true)
                    System.out.print("Passwords do not match, please enter the password again? ");
                    cPassword=Keyboard.readString();
                    System.out.print("Re-enter password? ");
                    tempPassword=Keyboard.readString();
                    System.out.println();
               String cType = CharCreate.createType();
               CharCreate alpha = new CharCreate(cName, pName, cPassword, cType);
          else
          System.out.println("Returning to Main Menu");
     public static String createType()
          System.out.println("Choose from the following archaetypes:");
          System.out.println("Foot Soldier\tHeavy Gunner\tCavalry\nMedic\t\tOfficer\t\tEngineer\nSpecial Operations");
          System.out.println();
          String omega = Keyboard.readString();
          System.out.println();
          while (omega.equalsIgnoreCase("foot soldier")!=true &&
               omega.equalsIgnoreCase("heavy gunner")!=true &&
               omega.equalsIgnoreCase("cavalry")!=true &&
               omega.equalsIgnoreCase("medic")!=true &&
               omega.equalsIgnoreCase("officer")!=true &&
               omega.equalsIgnoreCase("engineer")!=true &&
               omega.equalsIgnoreCase("special operations")!=true)
               System.out.println("Invalid choice, please try again?");
               System.out.println("Foot Soldier\tHeavy Gunner\tCavalry\nMedic\t\tOfficer\t\tSpecial Operations");
               System.out.println();
               omega = Keyboard.readString();
          return omega;
CLASS TWO
public class Cavalry extends Soldier
     public Cavalry(String n, String p, String p2)
          super(n,p,p2);
CLASS THREE
import java.io.*;
public class Soldier
     public Soldier(String n, String p, String p2) throws IOException
          String charName = n;
          String playerName = p;
          String password = p2;
          PrintWriter fileOut = new PrintWriter(new FileWriter(charName+".txt"));
          fileOut.println(charName);
          fileOut.println(playerName);
          fileOut.println(password);
          fileOut.close();
The error that JCreator is showing me is listed as follows:
C:\Documents and Settings\bellw\Desktop\Personal\Game\Cavalry.java:5: unreported exception java.io.IOException; must be caught or declared to be thrown
          super(n,p,p2);

Thank you for any assistance you may be able to provide.
If you have any suggestions, questions, solutions, please post here and/or e-mail me at [email protected]

Answer 1

Thanks, for now, I have imported java.io.* in all of my child classes.. and.. apparently in all my classes, period, and thrown IO exceptions in all of their methods. This seems to have remedied the problem, but I still do not understand why a class that does not do anything with files outside the .class should need these things.
Most of them are child classes of the Soldier class, which uses IO, but it's the only class. Every class I have that had some link, even indirectly, to it had to have java.io.* imported and have throws IOException put into every method. Why?
Also, thank you to everyone that replied.
