Tag: ENUM from char

One of my popular ways to make my code more readable is to make use of an ENUM.

If you have some “if” or “switch” statement:

             char myChar = 'D';
             if (myChar=='H') {
              //SOME CODE
              } else if (myChar=='V') {
                //SOME OTHER CODE
                 }

it does not say much about the functionality thats why I use enums

public enum myType {
        HORIZONTAL("H"),
        VERTICAL("V");
        private char directionToken;
        
        public static myType fromChar(char searchchar) {
            for (myType st : myType.values()) {
                if (st.directionToken == searchchar) {
                    return st;
                }
            }
            return null;
        }
        
        private myType(String transToken) {
            this.directionToken = transToken.charAt(0);
        }

        public char directionToken() {
            return directionToken;
        }
    }    

.....

             myType currRecordType = myType.fromChar(linechar[43]);
             switch (currRecordType) {
                 case HORIZONTAL:{
                     ...
                     break;
                     }
                     
                 case  VERTICAL:{
                     ...
                     break;
                 }
             }
