org.dromara.hutool.core.collection.partition.Partition<T>

org.dromara.hutool.core.collection.partition.AvgPartition<T>

org.dromara.hutool.core.collection.partition.RandomAccessAvgPartition<T>

Type Parameters:

T - 元素类型

All Implemented Interfaces:

Iterable<List<T>>, Collection<List<T>>, List<List<T>>, RandomAccess

public class RandomAccessAvgPartition<T>
extends AvgPartition<T>
implements RandomAccess

列表分区或分段（可随机访问列表）
通过传入分区个数，将指定列表分区为不同的块，每块区域的长度均匀分布（个数差不超过1）

     [1,2,3,4] -》 [1,2], [3, 4]
     [1,2,3,4] -》 [1,2], [3], [4]
     [1,2,3,4] -》 [1], [2], [3], [4]
     [1,2,3,4] -》 [1], [2], [3], [4], []
 

分区是在原List的基础上进行的，返回的分区是不可变的抽象列表，原列表元素变更，分区中元素也会变更。
