Learning about enums now. My enum here are the months in the year. I'm going to need to be able to calculate month to month so I needed them to have an ordering (January = 0, December = 11), I'll need to be able to access and print the number of days in a month and I'll need to be able to choose between printing the full (long) month name or an abbreviated (short) version.

I started off doing what I thought would declare my months and add the other data to them, but I'm already getting errors when I test compile. It says Cannot find symbol - variable JAN referring to the shortened version of January and it pops up one of those errors for each month.

Where have I gone wrong? Would really appreciate an explanation as well as correct code as this really seemed right from the 2 explanation examples I saw.

public enum Month { JANUARY(0,31,JAN), FEBRUARY(1,28,FEB), MARCH(2,31,MAR), APRIL(3,30,APR), MAY(4,31,MAY), JUNE(5,30,JUN), JULY(6,31,JUL), AUGUST(7,31,AUG), SEPTEMBER(8,30,SEP), OCTOBER(9,31,OCT), NOVEMBER(10,30,NOV), DECEMBER(11,31,DEC); private int order; private int dayTotals; private String SHORT; private Month(int o, int dT, String SHORT){ order = o; dayTotals = dT; SHORT = SHORT; } /** * Get the number of days in the month. Leap years are not considered. * Ex: January -> 31 * @return the number of days in a month */ public int getLength() { //TODO: Implement me return 0; } /** * Adds numberOfMonths to the current Month and returns what month it will then be. * @param numberOfMonths the number of months to look ahead * @return what month it will be numberOfMonths after the current month */ public Month plus(int numberOfMonths) { //TODO: Implement me return JANUARY; } /** * Return the name of the month in the requested style, either SHORT or default to LONG. For some months, * SHORT may be equal to LONG. * Ex: A SHORT style would return 'Jan' and the LONG style would return 'January' * @param style - the style the month should be returned in * @return the display name of the current month according to the requested style. */ public String getDisplayName(DisplayStyle style) { //TODO: Implement me return ""; } @Override public String toString(){ return name().substring(0,1) + name().substring(1).toLowerCase(); } }
