Question

Hi i am creating instance of Calendar Using:

Calendar calendarDate=Calendar.getInstance();
            calendarDate.set(2012, 6, 1,0,0,0);
                Date date1=calendar.getTime();

After that i create instance of java.util.date using:

Date date2=new Date(2012 - 1900,7-1, 01);

Now when i am trying to compare dates using following code:

System.out.println(date2.compareTo(date1));
System.out.println(date1.compareTo(date2));

it prints -1 and 1 instead of 0(zero).
Can any one help me to find what’s goes wrong ?

Try to clear the value of calendar before set a new one. This will solve your problem.

Calendar calendarDate=Calendar.getInstance();
calendarDate.clear();
calendarDate.set(2012, 6, 1,0,0,0);

Test for it:

import java.util.Calendar;
import java.util.Date;

import org.junit.Assert;

public class DateTest {

    @org.junit.Test
    public void test() {
        Calendar calendarDate=Calendar.getInstance();
        calendarDate.clear();
        calendarDate.set(2012, 6, 1,0,0,0);
        Assert.assertEquals(0, calendarDate.getTime().compareTo(new Date(2012 - 1900,7-1, 01)));
    }

}
