初始化100个元素的list,按容量等分成多个list

@Test
public void testInitAndPartition() {
    // 1.生成连续的100个数放入List(生成list)
    List fullList = IntStream.rangeClosed(0, 105).boxed().collect(Collectors.toList());
    // 2. 将List按照 capacity=20 等分成多个List(切分)
    List> partitionList = com.google.common.collect.Lists.partition(fullList, 20);
    // 3. 打印
    partitionList.stream().forEach(part -> System.out.println(part));
