根据这个操作步骤写一段java

由于这段日语文本缺少一些必要的上下文信息，例如类和方法的定义、参数类型和返回值等，因此无法直接将其转换为Java代码。以下是一个可能的实现示例，仅供参考： ``` // 假设存在SalesCompanyMasterDao和CommonUtil类 public class SalesCompanyService { public void processRequest(Request request) { List salesCompanies = new ArrayList<>(); if (request.getSalesCompanyCode() == null) { SalesCompanyMasterDao dao = new SalesCompanyMasterDao(); Condition condition = new Condition(); condition.setLogicalDeleteFlag(Constants.LOGICAL_DELETE_FLAG_UNDELETED); salesCompanies = dao.selectByCondition(condition); if (!salesCompanies.isEmpty()) { SalesCompany salesCompany = salesCompanies.get(0); salesCompany.setCode(salesCompany.getCode()); salesCompany.setName(salesCompany.getName()); } } else { SalesCompany salesCompany = new SalesCompany(); salesCompany.setCode(request.getSalesCompanyCode()); salesCompany.setName(request.getSalesCompanyName()); salesCompanies.add(salesCompany); } CommonUtil commonUtil = new CommonUtil(); String calendarLowerLimit = commonUtil.calculateCalendarLowerLimit(); // do something with the calendarLowerLimit } } public class CommonUtil { public String calculateCalendarLowerLimit() { Date baseDate = ...; // 系统日期-1个月的月末日 int days = 2; int calendarType = Constants.CALENDAR_TYPE_HEAD_OFFICE; Date calculatedDate = CommonUtil.calculateWorkingDay(baseDate, days, calendarType); Date currentDate = ...; // 当前系统日期 Date firstDayOfMonth = ...; // 当前系统日期所在月份的第1天 String calendarLowerLimit = null; if (currentDate.compareTo(calculatedDate) <= 0) { calendarLowerLimit = CommonUtil.formatDate(CommonUtil.addMonths(baseDate, -1), "yyyyMM"); } else { calendarLowerLimit = CommonUtil.formatDate(firstDayOfMonth, "yyyyMM"); } return calendarLowerLimit; } public static Date calculateWorkingDay(Date baseDate, int days, int calendarType) {
