jdk 1.6LinkedList+iterator 举例

package com.itcast.practice;

import java.util.Iterator;
import java.util.LinkedList;

public class test1
 {
  /**
   * 1、 创建一个类Sample，在main方法中定义一个ArrayList的集合类， 并向集合中添加任意多个同一种类型的元素，
   * 利用Iterator接口，遍历集合中的所有元素。
   */

  public static void main(String[] args) {
   EnumTest ee = new EnumTest("fuyuan", true, 24);
   EnumTest zz = new EnumTest("zhangsan", false, 19);
   // classcastexception 异常代码
   // List listtestList = (List) new LinkedList();
   LinkedList listtestList = new LinkedList();
   listtestList.add(ee);
   listtestList.add(zz);
   Iterator iterator = ((java.util.List) listtestList).iterator();
