package com.loongship.second;
public class Stack {
private int initSize;
private Node[] nodes;
private int index = 0;
/**
* 添加节点
*
* @param node
*/
public void addNode(Node node) {
if (nodes.length == initSize) {
Node[] target = new Node[initSize = initSize * 2];
System.arraycopy(nodes, 0, target, 0, nodes.length);
nodes = target;
}
nodes[index++] = node;
}
public Node pop() {
return nodes[index - 1];
}
public Node del() {
Node returnVal = pop();
nodes[index - 1] = null;
return returnVal;
}
public Stack(int initSize) {
this.initSize = initSize;
nodes = new Node[initSize];
}
public static void main(String[] args) {
Stack stack = new Stack(1);
stack.addNode(new Node());
stack.addNode(new Node());
stack.addNode(new Node());
System.out.println(stack);
stack.del();
System.out.println(stack);
}
}
