Java中將list集合按指定長度切分

一：切分方法：com.google.common.collect包下的Lists.partition方法。

二：maven引入依賴：

<dependency>
	<groupId>com.google.guava</groupId>
	<artifactId>guava</artifactId>
	<version>21.0</version>
</dependency>

三：實戰

package com.example.demo.partition;

import java.util.List;
import com.google.common.collect.Lists;

/**

public class ListsPartition {
    public static void main(String[] args) {
        List<String> strings=Lists.newArrayList("a","b","c","d","e","f","g","h","i");
        List<List<String>> lists=Lists.partition(strings,4);
        System.out.println(lists);
    }
}

打印結果：
