Equivalent List tool class

This tool class is used to divide the list list into an equal number of lists. For example, if the list has 1W data, divide it into 10 lists each with 1k data.

public class ListUtils {

    public static <T> List<List<T>> averageAssign(List<T> source, int limit) {
        if (null == source || source.isEmpty()) {
            return Collections.emptyList();
        }
        List<List<T>> result = new ArrayList<>();
        int listCount = (source.size() - 1) / limit + 1;
        int remaider = source.size() % listCount; // (先计算出余数)
        int number = source.size() / listCount; // 然后是商
        int offset = 0;// 偏移量
        for (int i = 0; i < listCount; i++) {
            List<T> value;
            if (remaider > 0) {
                value = source.subList(i * number + offset, (i + 1) * number + offset + 1);
                remaider--;
                offset++;
            } else {
                value = source.subList(i * number + offset, (i + 1) * number + offset);
            }
            result.add(value);
        }
        return result;
    }
