Thread: Need help with a loop

edit: nevermind, at first glance I thought polymorphic, but I see now it isnt... I hate polymorphic substitution.

Ok well just put it in a while loop, with the break statement being a switch.

Code:

import java.io.*;

public class PetTest {
    public static void main(String[] args) {
         while(true) {
    	 try {
            BufferedReader br = new BufferedReader(
                                new InputStreamReader(System.in));
			System.out.println("------------------------------------------------");
            System.out.println("Please Choose From the Following:\n 1. Dogs " +
                               "2. Cats 3. Fish 4. Birds  5. VIEW ALL ");
			System.out.println("------------------------------------------------");
            String line = br.readLine().trim();
            int selection = Integer.parseInt(line);
            String s = "";
            switch(selection) {
                case 1:
                    s = "dog";
                    break;
                case 2:
                    s = "cat";
                    break;
                case 3:
                    s = "bird";
                    break;
                case 4:
                    s = "fish";
                    break;
                case 5:
                    s = "View All";
                    break;
                case 6:
                    s = "EXIT";
                    break;
                default:
                    s = "unexected selection";
            }
            System.out.println("selection = " + s);
            Dog dog = null ;
            Cat cat = null;

            Bird bird = null;
            if(s.equalsIgnoreCase("exit"))
            {
                  break;
            }
            if(s.equalsIgnoreCase("dog") || s.equalsIgnoreCase("View All"))
            {
            dog = new Dog(4, 12, 50.00, "Terrier", Dog.DRY);
            System.out.println("\ndog = " + dog);
