Checking up with some real basic java mutator questions:

Given....

public class SimpleDate {

private String month;

private int dat;

private int year;

public static final int FIRST_YEAR = 1970;

....

Part A) Write a mutator method for the year that prevents the year from being set before the first year that computers started counting time

Part B) Write a mutator method for the month. You can assume that the value is provided by the method is valid

Part C) write a mutator method for day, if the value given to this methis is less than 1, it print "Days are greater than zero" Otherwise it should set the numbers of days to provided value OR the maximum days in the month. (30 days for april/june/september/novem... 28 for febuary... and rest with 31)
