How do I get constants name of an enum?

To get the constants name of an enumeration you can use the values() method of the enumeration type. This method return an array that contains a list of enumeration constants.

package org.kodejava.basic;

public enum Month {
    JANUARY,
    FEBRUARY,
    MARCH,
    APRIL,
    MAY,
    JUNE,
    JULY,
    AUGUST,
    SEPTEMBER,
    OCTOBER,
    NOVEMBER,
    DECEMBER
}

package org.kodejava.basic;

public class EnumValuesTest {
    public static void main(String[] args) {
        // values() method return an array that contains a list of the
        // enumeration constants.
        Month[] months = Month.values();
        System.out.println("Month size: " + months.length);

        // We can use for each statement to print each enumeration
        // constant.
        for (Month month : Month.values()) {
            System.out.println("Month: " + month);
        }
    }
}
