Given a sample code:

enum Year {

}

class EnumTest {
Year year;

public EnumTest(Year year) {
this.year = year;
}

public void tellItLikeItIs() {
switch (year) {
case JANUARY:
System.out.println("JANUARY is too cold.");
break;

case APRIL:
System.out.println("APRIL is less hot.");
break;

case JULY:
case JUNE:
System.out.println("JUNE is hottest.");
break;

default:
System.out.println("Rest are nice ");
break;
}}

public static void main(String[] args) {
EnumTest firstMonth= new EnumTest(Year.JANUARY);
firstMonth.tellItLikeItIs();
EnumTest thirdDay = new EnumTest(Year.APRIL);
thirdDay.tellItLikeItIs();
EnumTest fifthDay = new EnumTest(Year.JULY);
fifthDay.tellItLikeItIs();
EnumTest sixthDay = new EnumTest(Year.MAY);
sixthDay.tellItLikeItIs();
EnumTest seventhDay = new EnumTest(Year.JUNE);
seventhDay.tellItLikeItIs();

}}
