Problem with compile Calendar

[santunez]

Hello Friend

I have the following code:

-------------------------------------------------
import java.util.*
import java.util.Calendar;
import java.util.Date;
import java.util.GregorianCalendar;
import java.util.TimeZone;

public class gregoriano {

/**

* @param args the command line arguments

*/
// Logical Attribute
public static void main(String[] args) {

Calendar calendar = Calendar.getInstance();
calendar.clear();
calendar.set(1601,0,1,0,0);
long timeStamp = Long.parseLong(ADdate);
timeStamp = timeStamp / 10000 + calendar.getTime().getTime();
Date vDate= new Date(timeStamp);

// Physical Attribute

Calendar cal = new GregorianCalendar(TimeZone.getTimeZone("UTC"));
cal.clear();
cal.set(1601, 0, 1, 0, 0);
long longNum=(date.getTime() - cal.getTime().getTime()) * 10000;
v=Long.toString(longNum);
}
}
-----------------------------------------

The code is by change the format of calendar to gregorian, but when is compiled appears the following errors

-------------

The error message is telling you exactly what is wrong. It's telling you that you're using a bunch of variables that are never declared: ADdate, date, and v.

Solution:

1) don't do this. Always declare and initialize a variable before you try to use it.
2) Study what the error messages are telling you because most of the time, it will point you to what is wrong.

Buena suerte!
