Declaring Constructors, Methods, and Variables in an enum

NOTE: the order of the line of the code is important for the following:

public enum SORT_ORDER

{

  ACCESSED_ASCENDING("accessed_ascending"),   

  ACCESSED_DESCENDING("accessed_descending");

   

  private SORT_ORDER(String p_value)

  {

   this.m_value = p_value;

  }

  private final String m_value;

  @Override

  public String toString()

  {

    return m_value;

  }

}
