array problem

I am trying to create an array of a custom class. the user is asked with util scanner ("What kind of ant? (1 for Queen, 2 for Worker and 3 for Drone or -99 to quit)"); and the choice of the array are printed and the program ends when they enter a sentinel value. Here is the code I have so far.

Code:

---

public class driver
{
        public static void main(String Args[])
        {
                ant z = new ant();
                z.set_ant();
       
                ant ar[] = new ant[3];
                int count = 0;
                while(z.get_ant-ar() != "end")
                {
                        ar[count] = z.get_ant_ar();
                          count++;
                        System.out.println(ar[count]);
                       
                }
        }       

}

---

Code:

---

import java.util.Scanner;
public class ant extends insect
{
        Scanner input = new Scanner(System.in);
        private int z;
        private String ant;

        public void set_ant()
        {
                System.out.println("What kind of ant? (1 for Queen, 2 for Worker and 3 for Drone or -99 to quit)");
                z = input.nextInt();
        }
       
        }
        public String get_ant_ar()
        {
                if(z == 1)
               
                        ant = "Queen";
               
                if(z == 2)
               
                        ant = "Worker";
               
                if(z == 3)
               
                        ant = "Drone";
               
                return "ant";
        }               
}

wow this code has a lot of problems

1.

Code:

---

while(z.get_ant-ar() != "end")

---

this is a typo, should probably be

Code:

---

while(z.get_ant_ar() != "end")

---

2.
that while loop will never exit, because "z.get_ant_ar()" will never return "end"; count will keep incrementing; but when "count" gets to 3,

Code:

---

ar[count]

---

will be out of bounds

3.

Code:

---

ar[count] = z.get_ant_ar();

---

Code:

---

System.out.println(ar[count]);

---

it seems from these lines that "ar" should be a "String[]" instead of a "ant[]"

4.

Code:

---

return "ant";

---

the ant method get_ant_ar() always returns the literal string "ant". it sets the "ant" instance variable, but never uses it; perhaps you wanted to instead

Code:

---

return ant;
