In the previous article we looked at the DayOfWeek Enum from the Java 8 Date-Time API. Now let us take a look at the Month's enum.
The Month enum contains the singleton instances of the 12 months of the year as below,
- JANUARY :int value = 1
- FEBRUARY :int value = 2
- MARCH :int value = 3
- APRIL :int value = 4
- MAY :int value = 5
- JUNE :int value = 6
- JULY :int value = 7
- AUGUST :int value = 8
- SEPTEMBER :int value = 9
- OCTOBER :int value = 10
- NOVEMBER :int value = 11
- DECEMBER :int value = 12
Month january = Month.JANUARY;
Month march = Month.MARCH;
Month december = Month.DECEMBER;
System.out.println(january);
System.out.println(march);
System.out.println(december);JANUARY
MARCH
DECEMBERExample 2: Get the month of year numeric value
int january = Month.JANUARY.getValue();
int march = Month.MARCH.getValue();
int december = Month.DECEMBER.getValue();
System.out.println(january);
System.out.println(march);
System.out.println(december);1

12Example 3: Get number of days in a month
To get the number of days in a month we can make use of length(), minLength() and maxLength()
int january = Month.JANUARY.maxLength();
int february = Month.FEBRUARY.maxLength();
int february1 = Month.FEBRUARY.minLength();
int february2 = Month.FEBRUARY.length(true);
int february3 = Month.FEBRUARY.length(false);
System.out.println(january);
System.out.println(february);
System.out.println(february1);
System.out.println(february1);
System.out.println(february2);
System.out.println(february3);31

import java.time.Month;
import java.time.format.TextStyle;
import java.util.Locale;
public class Example {
public static void main(String... args) {
getMonthWithType(Month.JANUARY,Locale.US);
getMonthWithType(Month.FEBRUARY,Locale.US);
getMonthWithType(Month.MARCH,Locale.US);
getMonthWithType(Month.APRIL,Locale.US);
getMonthWithType(Month.MAY,Locale.US);

getMonthWithType(Month.JULY,Locale.US);
getMonthWithType(Month.AUGUST,Locale.US);
getMonthWithType(Month.SEPTEMBER,Locale.US);
getMonthWithType(Month.OCTOBER,Locale.US);
getMonthWithType(Month.NOVEMBER,Locale.US);
getMonthWithType(Month.DECEMBER,Locale.US);
}
private static void getMonthWithType(Month month, Locale locale) {
String monthName = "Month" + month.name() +"\n";
String fullName = "FULL: "+ month.getDisplayName(TextStyle.FULL,locale) +"\n";
String fullStandAloneName = "FULL_STANDALONE: "+ month.getDisplayName(TextStyle.FULL_STANDALONE,locale) +"\n";
String shortName = "SHORT: "+ month.getDisplayName(TextStyle.SHORT,locale) +"\n";
String shortStandaloneName = "SHORT_STANDALONE: "+ month.getDisplayName(TextStyle.SHORT_STANDALONE,locale) +"\n";
String narrowName = "NARROW: "+ month.getDisplayName(TextStyle.NARROW,locale) +"\n";
String narrowStandAloneName = "NARROW_STANDALONE: "+ month.getDisplayName(TextStyle.NARROW_STANDALONE,locale) +"\n";
System.out.println(monthName + fullName + fullStandAloneName + shortName + shortStandaloneName + narrowName + narrowStandAloneName);
}
}
