使用ListIterator获取上一个和下一个索引

import java.util.ListIterator;//n o w j a v a . c o m - 时代Java 提 供

import java.util.ArrayList;

 

public class Main {

 

  public static void main(String[] args) {

    ArrayList aList = new ArrayList();

    aList.add("1");

    aList.add("2");

    aList.add("3");

    aList.add("4");

    aList.add("5");

   

    ListIterator listIterator = aList.listIterator();

 

    System.out.println("Previous Index is : " + listIterator.previousIndex());  

    System.out.println("Next Index is : " + listIterator.nextIndex());

   

    listIterator.next();

   /** 来 自 N  o w  J a v a . c o m**/

    System.out.println("After increasing current position by one element : ");
