Hi every One
I'm Try to do program to calculate the Over Time, I'm working with 24
hour not A.M.& P.M. and this is my Time format (HH:MM:SS) (00:00:00).
But how can I use operand (+, -) with Time
See Stefan for the answer.
An alternative follows.
This is my Code
/////////////////////////////////////////////////////////////////////
import java.sql.Time;
import java.util.Date;
public class OverTimeDetailsDataClass {
String Emp_ID;
String OverTime_Doc_NO;
String OverTime_Date;
Time OverTime_Start_Time;
Time OverTime_End_Time;
Time OverTimeTotalHours;
OverTime_Start_Time =
Time.valueOf(OverTimeFromjTextField.getText());
OverTime_End_Time = Time.valueOf(OverTimeTOjTextField.getText());
OverTimeTotalHours = OverTime_End_Time - OverTime_Start_Time;
}
import java.sql.Time;
import java.util.Calendar;
import java.util.Locale;
import java.util.TimeZone;
import javax.swing.JTextField;
public class OT {
public static void main(String[] args) {
JTextField OverTimeFromjTextField = null;
JTextField OverTimeTOjTextField = null;
Time OverTime_Start_Time;
Time OverTime_End_Time;
// Be aware: read the documentation for java.util.Calendar
TimeZone timeZone = TimeZone.getDefault();
Locale locale = Locale.getDefault();
Calendar startTime = Calendar.getInstance(timeZone,locale);
Calendar endTime = Calendar.getInstance(timeZone,locale);
OverTime_Start_Time =
Time.valueOf(OverTimeFromjTextField.getText());
OverTime_End_Time = Time.valueOf(OverTimeTOjTextField.getText());
startTime.setTime(OverTime_Start_Time);
endTime.setTime(OverTime_End_Time);
// use the java.util.Calendar.add(int field, int amount) method
// as described in the documentation.
}
}
