Thread: Problem with code

I have a generic LinkedStack with a Node class and a number of methods
LinkedStack<T>{
class Node<T>{}//
void push(T item){}//
void push(FancyStack<T> s){}//
T pop(){}
boolean isEmpty(LinkedStack<T> stk){}
T peek(){}//
LinkedStack<T> rev(){}//reverses elements in this stack
}

When I create a new LinkedStack, push items onto it, and print the stack, I get memory addresses and not items in the stack.
What am I doing wrong?
Here's my code

import java.util.NoSuchElementException;
//import java.util.Stack;
public class LinkedStack<T>{
	public class Node<T>{
		private T data;
		private Node<T> link;
		public Node(T data,Node<T>link){
			this.data=data;
			this.link=link;
		}//Node constructor
	public void SetData(T info){data =info;}
 
	public T getData(){return data;}
 
	public void setLink(Node<T> newLink){link=newLink;}
 
	public Node<T> getLink(){return link;}
}//end of node
 
private Node<T> high=null;//
public void push(T thing){//this push
	high=new Node<T>(thing,high);
	}
 
public void push(LinkedStack<T> stk){
	final int MAX= stk.size();
	for(int i=0;i<MAX;i++){
		this.push(stk.pop());}}//
 
public T peek(){
	if(high==null){throw new NoSuchElementException();}
	else
		return high.getData();
	}
 
public T pop(){
		T thing=peek();
		high=high.link;
		return thing;
	}
 
public boolean isEmpty(LinkedStack<T> stack){
	return(high==null);
}
 
int hesabu=0;
public int size(){
	hesabu++;
	return hesabu;
}
 
public LinkedStack<T> rev(){
	LinkedStack<T> revStk= new LinkedStack<T>();
	final int LEN= this.size();
	for(int j=0;j<LEN;j++){
		revStk.push(this.pop());}
	return revStk;//end of method
		} 
}//end of LinkedStack

So for example when I create a new LinkedStack object
as in;

LinkedStack<String> stk=new LinkedStack<String>();

and push things onto it as in

stk.push("Me");
stk.push("Me too");
stk.push("Me me me");
stk.push("Me myself and I");

When I print out the stack like

System.out.println(stk)

I get an erorr of the sort

LinkedStack@56r3t333

I'm confused so any help is appreciated

Thanks for that
