代码的坏味道之IF语句
if (employeePositionList != null&& () > 0) {
for (EmployeePosition ep : employeePositionList) {
(().getIdx(), ());
}
(());
}
if (()!= null && () !="")
(() + " " + time);
if (()!=null &&
()!="")

代码的坏味道之IF语句

} catch (IOException e) {

List<EmployeeMain> empList = new ArrayList<EmployeeMain>();
if (employeePositionList != null&& () > 0) {
for (EmployeePosition ep : employeePositionList) {
