JAVA 获取一组数据中的多组连续数据集合

给定一组数据，返回该数据中多组连续数据集合。

例如:

给定 [2, 3, 4, 6, 8, 10, 11, 12, 15, 16]

返回: [2, 3, 4]，[6]，[8]，[10,11,12]，[15,16]

使用java语言写的，逻辑很简单，应该都能看得懂，就直接贴代码了:

/**
 * 获取列表中多组连续数据
 * @param list 原数据
 * @return 多组连续数据
 */
public static List<List<Integer>> getSerialNumList(List<Integer> list) {
    List<List<Integer>> resultList = new ArrayList<>();
    List<Integer> arrList = new ArrayList<>();
    resultList.add(arrList);
    if (list.size() == 1) {
        resultList.get(resultList.size() - 1).add(list.get(0));
        return resultList;
    }
    for (int i = 0; i < list.size(); i++) {
        Integer nextNum = list.get(i + 1);
        Integer nowNum = list.get(i);
        if (nextNum - nowNum != 1) {
            resultList.get(resultList.size() - 1).add(nowNum);
            arrList = new ArrayList<>();
            resultList.add(arrList);
        } else {
            arrList.add(nowNum);
        }
        if (i + 1 == list.size() - 1 ) {
            arrList.add(nextNum);
            break;
        }
    }
    return resultList;
}

public static void main(String[] args) {
    Integer[] arr = {2, 3, 4, 6, 8, 10, 11, 12, 15, 16};
    List<Integer> list = new ArrayList<>(Arrays.asList(arr));
    List<List<Integer>> serialNumList = getSerialNumList(list);
    serialNumList.forEach(System.out::println);
}
