Gregorian Calendar program

[redmaverick]

I am trying to execute this program, but I am getting errors
this is the code

import java.util.*;
public class DateUtils
{

static final int MILLS_IN_DAY = 24*60*60*1000;
 
public static Date getCurrentDate()
{
GregorianCalendar currentDate = new GregorianCalendar();
currentDate.set(Calendar.HOUR,0);
currentDate.set(Calendar.MINUTE,0);
currentDate.set(Calendar.SECOND,0);
return currentDate.getTime();
}

public static Date createDate(int year, int month, int day)
{
GregorianCalendar date =  new GregorianCalendar(year,month,day);
return date.getTime();
}


public static Date stripTime(Date date)
{
GregorianCalendar currentDate = new GregorianCalendar();
currentDate.setTime(date);
currentDate.set(Calendar.HOUR,0);
currentDate.set(Calendar.MINUTE,0);
currentDate.set(Calendar.SECOND,0);
return currentDate.getTime();
}


public static int daysDiff(Date date1, Date date2)
{
date1 = stripTime(date1);
date2 = stripTime(date2);
long longDate1=date1.getTime();
long longDate2=date2.getTime();
long longDiff = longDate2 - longDate1;
return (int)(longDiff/MILLS_IN_DAY);

}

 
}

I am testing this with

import java.util.*;
public class Tes{
  public static void main(String[] args) {

GregorianCalendar currentGC =  new GregorianCalendar();
int currentYear = currentGC.get(Calendar.YEAR);
Date currentDate = DateUtils.getCurrentDate();
Date christmas = DateUtils.createDate(currentYear,Calendar.DECEMBER,25);
int daysToChristmas = DateUtils.daysDiff(currentDate, christmas);
DateFormat dateFormat = DateFormat.getDateInstance(DateFormat.LONG);
String formattedDate = dateFormat.format(currentDate);
System.out.println("Today" + formattedDate);
System.out.println("There are"+daysToChristmas);
}
}

The first code compiled fine. But I am having errors with the second one.

Tes.java:11: cannot find symbol
symbol  : class DateFormat
location: class Tes
DateFormat dateFormat = DateFormat.getDateInstance(DateFormat.LONG);
^
Tes.java:11: cannot find symbol
symbol  : variable DateFormat
location: class Tes
DateFormat dateFormat = DateFormat.getDateInstance(DateFormat.LONG);
                                                   ^
Tes.java:11: cannot find symbol
symbol  : variable DateFormat
location: class Tes
DateFormat dateFormat = DateFormat.getDateInstance(DateFormat.LONG);
                        ^
3 errors

How should I correct the 3 errors?

code is from a text book

When do you think the compile time error 'symbol not found comes up'? What does your text book say about such errors? The example you posted seems a pretty bold one for someone who has just started out with Java.

Anyways, the error message means that the compiler doesn't know about the token 'DateFormat'; `import' the class in question and you should be good to go.

Dear Friend, you have to use import java.text.*; since the Format and DateFormat are a part of java.text package. If you do that you won't get any error message.

Thanks for the help. It is working now. I know that this is pretty bold for a beginner. But I am understanding the concept behind it and I think that by understanding more such programs I will be able to become better with time.

With the internet and helpful communities like these willing to give a helping hand, I am sure I can improve myself.
