java - Value entered for one entry is stored for other entries instead of unique values -

i have module have update attendance of each student. code below:

public void updatedailyattendance(actionrequest areq, actionresponse ares) throws exception{   int totalemployees = employeelocalserviceutil.getemployeescount(); string attendancevalue = getattendancevalue(areq); //long attpkey = counterlocalserviceutil.increment(employee.class.getname()); (int = 0; < totalemployees; i++) { // use attendancevalue update employee entry //string attendancevalue = getattendancevalue(areq); // parametervalue value of radio button parameter   long attpkey = counterlocalserviceutil.increment(employee.class.getname());  attendance newattendanceinstance = new attendanceimpl(); newattendanceinstance.setattid(attpkey);                             newattendanceinstance.setattstatus(attendancevalue);                         attendancelocalserviceutil.addattendance(newattendanceinstance); 

} }

 private string getattendancevalue(actionrequest areq) {  enumeration parameters = areq.getparameternames();  while (parameters.hasmoreelements()) {    string parametername = parameters.nextelement().tostring(); if (parametername.startswith("updateattendance")) {     return areq.getparameter(parametername);  }  } throw new illegalstateexception("parameter updateattendance cannot found!!"); } 

when use above code database gets updated attendance (present/absent entered first employee taken value other employees though mark different values(present/absent) other employees

how should modify above code radio button value entred each employee stored ?

you attendancevalue once before loop. getattendancevalue returns 1 string, how can attendancevalue can different between 2 students?

string attendancevalue = getattendancevalue(areq); 

that's why attendancevalues same. need updating value every employee inside loop.
