第一步：修改pom文件
<!-- https://mvnrepository.com/artifact/com.google.guava/guava -->
<dependency>
<groupId>com.google.guava</groupId>
<artifactId>guava</artifactId>
<version>23.0</version>
</dependency>
第二步：调用Lists API
package com.example.demo;
import com.google.common.collect.Lists;
import org.apache.commons.lang.StringUtils;
import java.util.*;
import java.util.stream.Collectors;
public class Tq {
public static void main(String[] args) {
long st = System.currentTimeMillis();
List<Integer> list = new ArrayList<>();
//43495
for (int i = 0; i < 100; i++) {
list.add(i);
}
List<List<Integer>> partition = Lists.partition(list, 10);
System.out.println("partition = " + partition);
}
}
网上写的像下面这种都太麻烦了，遂产此博客，方便
