Hello Experts,,

Please help to my program,, this program will input Timein, Timeout,Otin,Otout, and holiday,, in 5 Days(from Monday - Friday),,
my problem is i dont know how to compute the Timein and Timeout(ex. Monday timein: 8:30 and Monday Timeout: 17:30) i need the result of total hours is 9,, hope u can help me,,
Sorry for my bad english!!,, tnx in advance,,

Is this of any help?

Code:

---

import java.util.*;
...
Calendar cal = Calendar.getInstance();

---

Setting TimeIn

Code:

---

long timeIn = cal.getTimeInMillis();

---

Setting TimeOut

Code:

---

long timeOut = cal.getTimeInMillis();

---

Calculation for total hours

Code:

---

        long total = timeOut - timeIn;
        long hour = total / (1000 * 3600);
        long min = (total % (1000 * 3600) / (1000 * 60));
        // long sec = (total % (1000 * 60) /1000); // if you need seconds

---

I didn't try this right now but it should work.

Sorry, I just read end of your code and realise the way you are entering TimeIn and TimeOut. You can have some method for calculating milliseconds for TimeIn and TimeOut. It could looks like as follows:

Code:

---

public long setTimeIn(int hour, int min){
   
    Calendar cal = Calendar.getInstance();
    cal.set(Calendar.HOUR_OF_DAY, hour);
    cal.set(Calendar.MINUTE, min);
    long timeIn = cal.getTimeInMillis();
    return timeIn;

}

---

Just find a way to provide this method with int hour and int minutes from your System.in.
