Basic toString

Question

Argh! this is such a simple question but my mind aint working and you know the rest....
here is my code snipet..
public class Sieve
     private boolean[] eratostenes;
     private long j;
     public Sieve (int n)
          boolean[] eratostenes = new boolean [n];
          long j = 2;
               for (int i = 2; i < eratostenes.length; i += 2)
                    eratostenes[i] = false;
                for (int i = 3; i < eratostenes.length; i += 3)
                    eratostenes[i] = false;
      public String toString()
           String current= new String();
           String total = new String();
           current = "dog";
           /*for (int i = 2; i < eratostenes.length; i ++)
                if (eratostenes[i] == false)
                     current = (i + "   ");
                     total = (total + current);
           return(j);
}the problem is in the return statment! it wont accept the int(just a test variable, eventually there will be an array of ints i.e eratostenes..). How can I convert that int to a string? any help is appreciated

yes thanks you Sagnam! The "" + J is total cheese! I am looking at a tutorial simialr to what I am trying to do and they threw a "\t" at the end of their return statement, which confused me :/
