用Enumeration 来访问 Iterator

 

package namespace;import java.io.*;import java.util.*;public class IOTest {public static void main(String args[]) throws IOException {ArrayList<String> list = new ArrayList<String>();list.add("one");list.add("two");list.add("three");list.add("four");final Iterator<String> it = list.iterator();  //必需定义为终态.Enumeration<String> en = new Enumeration<String>() {public boolean hasMoreElements() {return it.hasNext();}public String nextElement() {return it.next();}};while(en.hasMoreElements()){System.out.println(en.nextElement());}}2011/11/2  13:23:32}
