1.用法很简单只需要调用一个API就行

package com.atguigu.yygh.cmn.controller;

import org.apache.commons.collections4.ListUtils;

import java.util.ArrayList;
import java.util.List;

public class Test2 {

    public static void main(String[] args) {
        ArrayList<Student> list = new ArrayList<>();
        list.add(new Student("张三",16));
        list.add(new Student("张四",19));
        list.add(new Student("李五",15));
        list.add(new Student("张马六",16));
        list.add(new Student("张马六",16));
        List<List<Student>> partitionList = ListUtils.partition(list, 2);
        System.out.println("3666"); //分块后的大小  2   2   1
        System.out.println(partitionList.size());

    }

}
