plz check my coding...

What happens when you run the program?
What inputs are you providing, and what outputs is it giving back to you?
What outputs do you expect to get back?
Are you getting any exceptions? If so, please post the exception message.

can you post the error message?

DayType d = new DayType(SUNDAY);

What is SUNDAY?

if you mean this

final static int SUN = 0;

then please change the above SUNDAY TO SUN.

After changing this it running fine, but one logical error in your previous day function.

Secondly,

if your current day in sun=0
then previous day will be -1;

so what it will print.

public int previousDay(){
int prevDay;
prevDay = day - 1;
return prevDay;
}
