You can use Calendar API to get the day of the week.Let's say the date is 6th Aug 2002.Set the calendar object as following:
cal.set(2002,7,6);
where - 2002 is the year
7 - month (Jan is 0 so Aug is 7)
6 - date

  
import java.util.*;
class Test{
  public static void main(String args[]){
   Calendar cal = Calendar.getInstance();
   cal.set(2002,7,6);
   System.out.println("Day is "+cal.get(cal.DAY_OF_WEEK));
  }
}

Output :
Day is 3
which is TUESDAY
(SUNDAY -1,MONDAY - 2 and so on)

I don't think that this is too hard using the java.text.SimpleDateFormat class:

//create the date format in which you will parse the date
SimpleDateFormat df = new SimpleDateFormat( "dd/MM/yy" );
//parse in the date
java.util.Date date = df.parse( "06/08/2002");
//change the pattern to output the day of week
df.applyPattern( "EEE" );
//print the formatted date out
System.out.println( "Day of Week = " + df.format( date ) );
