Pday=2;
Pmonth=1;
Pyear=1988;
}
Pdate(int da,int mo,int ye){
this.Pday=da;
this.Pday=mo;
this.Pday=ye;
}
public static void main(String args[]){
Pdate date1=new Pdate(2,1,1988);
Pdate date2=new Pdate();
{if (date1.equals(date2))

We have modified your code. It will check the two dates properly.
package examples;
import java.util.*;
public class Pdate extends Date{
int Pday;
int Pmonth;
int Pyear;
int d1,d2;
Pdate()
{
Pday=2;
Pmonth=1;
Pyear=1988;
}
Pdate(int da,int mo,int ye){
this.Pday=da;
this.Pday=mo;
this.Pday=ye;
}
public static void main(String args[]){
Pdate date1=new Pdate(2,1,1988);
Pdate date2=new Pdate();
if (date1.equals(date2))
System.out.println(date1+"Awesome date"+date2);
else
System.out.println(date1+"Blah date"+date2);
}
}

}
}

no it doesn't check the date properly still. both date1 and date2 are same, yet it still says "Blah date"..
also i don't understand how extending Date would be helpful, can u plz explain why?
Thanks..
