class enum_ex{
enum Name_OF_Setofvalues{value_1,value_2,value_3,...........value_n}
}

Example

Days_Of_Weeks{Monday,Tuesday,Wednesday,Thursday,Friday,Saturday,Sunday}

Example

program 1

class Enum_ex{
        enum months
        {
        January,February,March,April,May,June,July,
        August,September,October,November,December
        }
   public static void main (String args[]){
    for(months m:months.values())
    {
       term_End(m);
    }
   }
   
   public static void term_End(months m){
   if(m.equals(months.December)){
        System.out.println(m+" :End of year");
   }
   else
   {
     System.out.println(m+" :months of year");
   }
   }
}

 

When the above code is compiled and executed, it will produce the following results
