(2) The first line inside the enum should be a list of constants and then other things like methods, variables and constructors

(3) According to Java naming convention, it is recommended that we name constant with all capital letters. 

Example:—

    enum Color

          {

            RED, GREEN, BLUE;

           }

       public class Test

           {

        //Driver methods

      public static void main (String[ ]args) 

          }

       Color c1=Color.RED;

      System.out.println(c1) ;

     }

     }

Output:—

RED
