Thread: What am I doing wrong with this stack? Java Programming?

I have a program that reads the names of countries from a file, prints them to the screen then prints thm from the stack. However when it prints from the stack this is the resulting output:

Returning what is in the stack

Country@42e816
Country@9304b1
Country@190d11
Country@a90653

Can someone help me please?
This is the code:

public class Country {
	String name;
 
}

import java.io.*;
 
public class StackOfObjects {
    private Node first;
 
 
    private class Node {
        private Object item;
        private Node next;
    }
 
 
    public StackOfObjects() {
        first = null;
    }
 
 
    public boolean isEmpty() { return (first == null); }
 
 
    public void push(Object item) {
        Node oldfirst = first;
        first = new Node();
        first.item = item;
        first.next = oldfirst;
    }
 
 
    public Object pop() {
        if (isEmpty()) throw new RuntimeException("Stack underflow");
        Object item = first.item;      
        first = first.next;            
        return item;                   
    }
 
 
    // a test client
    public static void main(String[] args) {
        StackOfObjects stack = new StackOfObjects();
 
 
 	   try{
 
 		    FileInputStream fstream = new FileInputStream("textfile.txt");
 
 		    DataInputStream in = new DataInputStream(fstream);
 		        BufferedReader br = new BufferedReader(new InputStreamReader(in));
 		    String strLine;
 		   System.out.println ("Returning what is in the file\n");
 
 		    while ((strLine = br.readLine()) != null)   {
 
 			      System.out.println (strLine);
 		    	Country count=new Country();
 		    	count.name=strLine;
 		    	stack.push(count);
 
 
 		    }
 		   System.out.println ("\nReturning what is in the stack\n");
 		    while( ! stack.isEmpty() ){
 		    	Object s=(Object) stack.pop();
 		        System.out.println(s);
 		    }
 
 
 		    in.close();
 		    }catch (Exception e){
 		      System.err.println("Error: " + e.getMessage());
 		}
 
    }
}

It appears to be returning the memory addresses of the items in the stack...I think. I've had this happen a few times before. Try

System.out.println ("\nReturning what is in the stack\n");
 		    while( ! stack.isEmpty() ){
 		    	Object s=(Object) stack.pop();
 		        System.out.println(String.ValueOf(s));
 		    }

Thanks to all! I've gotten it to work!

while( ! stack.isEmpty() ){
Country s=(Country) stack.pop();
System.out.println(s.name);
}
