You spelt "Calender" wrong. It should be spelt "Calendar"

Also, just glancing at it, your getSalary method is wrong. Should be ...getSalary() not ;...that's just a thought, I'm new to JAVA, but you definitely spelt Calendar wrong.

vacationDays = (year - yy) = VACATION_DAYS_PER_YEAR;

That doesn't seem right. I don't know what you want to do so i can't really help, but since "VACATION_DAYS_PER_YEAR" is set to final and set to "30" then you are basically taking the 30 and assigning it to "(year -yy)" and then assigning "(year-yy)" to "vacactionDays" I'm bad at explaining, but can't do that, I think.

When you do more than one equal like that it usually for a 2 things with the same value like:
"int x = y = 4;"
