Java对list进行分页排序（假分页）

代码如下，直接复制即可

public List<RiskRankForUnitVo> handleListPage(List<RiskRankForUnitVo> list, int currentPage , int pageSize) {
        int totalCount = list.size(); //总数量
        int pageCount = 0; //总页数
        List<RiskRankForUnitVo> subyList = null;
        int m = totalCount % pageSize;
        if (m > 0) {
            pageCount = totalCount / pageSize + 1;
        } else {
            pageCount = totalCount / pageSize;
        }

        if (m == 0) {
            subyList = list.subList((currentPage - 1) * pageSize, pageSize * (currentPage));
        } else {
            if (currentPage == pageCount) {
                subyList = list.subList((currentPage - 1) * pageSize, totalCount);
            }
            if (currentPage< pageCount){
                subyList = list.subList((currentPage - 1) * pageSize, pageSize * (currentPage));
            }
        }
        if (currentPage >pageCount){
            return null;
        }
        return subyList;
    }
