Først en Node pladsholder : Kode /** * A Node is an object that holds an int and a link * to the next Node. It can be used to build linked * lists of ints. */ public class Node { private int data; // Each node has an int... private Node link; // ...and a link to the next Node /** * Node constructor. * @param theData the int to store in this Node * @param theLink a link to the next Node */ public Node(int theData, Node theLink) { data = theData; link = theLink; } /** * Accessor for the int data stored in this Node. * @return our int item */ public int getData() { return data; } /** * Accessor for the link to the next Node. * @return the next Node */ public Node getLink() { return link; } } ..og så intStack klassen der gør brug af Node : Kode /** * An IntStack is an object that holds a stack of ints. */ public class IntStack { private Node top = null; // The top Node in the stack /** * Test whether this stack has more elements. * @return true if this stack is not empty */ public boolean hasMore() { return (top != null); } /** * Pop the top int from this stack and return it. * If the stack is empty we return 0 and leave the * stack empty. * @return the popped int or 0 if the stack is empty */ public int pop() { Node n = top; if (n == null) return 0; top = n.getLink(); return n.getData(); } /** * Push an int on top of this stack. * @param data the String to add */ public void push(int data) { top = new Node(data,top); } } ..source code fra : http://www.webber-labs.com/mpl/source%20code/ </MOLOKYLE>
