使用迭代器迭代元素ArrayList

 

import java.util.ArrayList;/*来自 NowJava.com - 时  代  Java*/

import java.util.Iterator;

 

public class Main {

 

  public static void main(String[] args) {

    ArrayList arrayList = new ArrayList();

   

    arrayList.add("1");

    arrayList.add("2");

    arrayList.add("3");

    arrayList.add("4");

    arrayList.add("5");

   

    Iterator itr = arrayList.iterator();

   //来自 nowjava

    System.out.println("Iterating through ArrayList elements...");

    while(itr.hasNext()){

      System.out.println(itr.next());

    }   

  }

}
