java - Need to use Enum -

i clear advanced use of enum in java. many of points differentiate them regular classes , tells need clear me.

can give practical example sample code advanced enum? can elaborate

where should avoid classes , should use enum instead

.

please dont confused. not asking how use enum or use of enum. there many questions , answers on this. looking real time/ live / practical example should avoid other data type or classes.

try this example:

public enum day {     sunday, monday, tuesday, wednesday,      thursday, friday, saturday  } 

usage:

public class enumtest {     day day;      public enumtest(day day) {         this.day = day;     }      public void tellitlikeitis() {         switch (day) {             case monday: system.out.println("mondays bad.");                          break;              case friday: system.out.println("fridays better.");                          break;              case saturday:             case sunday: system.out.println("weekends best.");                          break;              default:     system.out.println("midweek days so-so.");                          break;         }     }      public static void main(string[] args) {         enumtest firstday = new enumtest(day.monday);         firstday.tellitlikeitis();         enumtest thirdday = new enumtest(day.wednesday);         thirdday.tellitlikeitis();         enumtest fifthday = new enumtest(day.friday);         fifthday.tellitlikeitis();                } }
