Question

Java: Can any one tell me why I have red lines for the value() and valueOf() and how I can fix it where the *** is at beginning of line.

import java.io.FileReader;

import java.util.ArrayList;

import java.util.Arrays;

import java.util.Properties;

public class Direction {

public ArrayList<Direction> synonyms;

public enum Synonyms {

//Values

N, S, E, W, NE, NW, SE, SW, UP, DOWN, UNKNOWN;

//Instance variable

ArrayList<Direction> synonyms;

//Default constructor

private Synonyms() {

}

}

//Class constructor

public Direction() {

synonyms = new ArrayList<>();

try {

//Read properties file

FileReader reader = new FileReader("direction.properties");

//Properties object

Properties p = new Properties();

//Load properties from file

p.load(reader);

//Get properties value

String strDirection = p.getProperty("direction");

//Check if enum contains value or not

if (Arrays.asList(Direction.values()).contains(strDirection)) {

//Add value in arraylist

synonyms.add(Direction.valueOf(strDirection));

}

} catch (Exception e) {

System.err.println(e);

}

}

public static void main(String[] args) {

//Create object

Direction ex = new Direction();

//Print Array

for (Direction dir : ex.synonyms) {

System.out.println(dir);

}

}

}

Explanation / Answer

you are getting error because values() and valueOf() methods belongs to enum class. You are using Direction class for both method, if you use Synonyms which is enum class, you won't get any issue for these two methods.

Synonyms.values()

Synonyms.valueOf()
