Here is the program that needs to be done
You are to prompt the user for a 3-digit ID and a birthdate for each college student. For the birth date, prompt for 2 intergers in order month, day, and year. Be sure to validate the birth date. The last student ID will be 000.
You are to out the ID and birth date for each student. The birth date should be output in the format February 15, 1982. Also output how many students were processed, how many of the students had a February 29th birth date, and the birth date of the oldest student.
HERE IS WHAT I HAVE AS OF NOW

p.readData();
while(!(p.studentId.equals("000")))
{
if (p.dataValid(p))
{
p.totalStudents();
if (base.ckBirthDate(p))
p.updateBirthDateTotal();
p.formatMonth();
p.writeStudentData(p);
p.readData();
}
}
p.writeOutcomes();
}
}
