How can i display an enum without all informations

Question

Hello i have a Planet class like below and i want to display Enum like MERCURY EARTH Etc ... without the informations between parenthesis and i'm using the CommonName inside the parenthesis like MERCURE , TERRE to search and display the Enum

public  enum Planet {

    MERCURY(0.387,"MERCURE") , VENUS(0.722,"VÉNUS"), EARTH(1.0,"TERRE"), MARS(1.52,"MARS"), JUPITER(5.20,"JUPITER"),
    SATURN(9.58,"SATURNE"),  URANUS(19.2,"URANUS"),  NEPTUNE(30.1,"NEPTUNE");
    private double  distance;
    private String commonName;
    




    
    private Planet(double v, String c) {
        distance = v;
        commonName = c;
    }

    public  double getDistanceFromTheSunInAstronomicalUnit(double distance) {
        return distance;
    }


    public  String getCommonName() {
        return commonName;
    }

    @Override //
    public  String toString() {
        return ""+commonName+ " ("+distance+")";
    }
}

And i have this function

 Optional <Planet> Dept = Arrays.stream(Planet.values())
                        .filter(e -> e.getCommonName().equals(Dep))
                        .findFirst();

                System.out.println(Dept.get());

i'm trying to display the Enum without the informations between the parenthesis and comparing the CommonName with an input(Dept) but the problem is everytime i get the informations inside the parenthesis

Anyone can help me please ?

You can search value like this:

public static void main(String[] args) {
    Optional <Planet> Dept = Arrays.stream(Planet.values())
            .filter(e -> e.name()==Planet.MERCURY.name())
            .findFirst();

    System.out.println(Dept.get());
}

Or Like This:

public static void main(String[] args) {
    String valueYouSearch="MERCURY";
    Optional <Planet> Dept = Arrays.stream(Planet.values())
            .filter(e -> e==Planet.valueOf(valueYouSearch))
            .findFirst();

    System.out.println(Dept.get());
}
