让开发效率爆表的Guava ---- Lists列表

Guava对JDK  List的扩展， 方便增加list到list中， 方便拆分list

package com.wenniuwuren.collections;

import java.util.Iterator;
import java.util.List;

import com.google.common.collect.Lists;

public class ListsTest {

	public static void main(String[] args) {
		Person person1 = new Person("lilei", 50);
		Person person2 = new Person("hanmeimei", 40);
		Person person3 = new Person("kangkang", 20);
		Person person4 = new Person("mary", 20);
		List<Person> personList = Lists.newArrayList(person1, person2, person3, person4);
		// 拆分成[person1, person2, person3], [person4]   第二个参数为拆分长度
		List<List<Person>> subList = Lists.partition(personList, 3);
		Iterator<List<Person>> i = subList.iterator();
		while(i.hasNext()) {
			List<Person> listTemp = (List<Person>)i.next();
			Iterator<Person> iTemp = listTemp.iterator();
			while(iTemp.hasNext()) {
				System.out.println(iTemp.next().getName());
			}
		}
	}

}
