Objects and their properties

You decide to recall the happy days of your childhood and play Heroes. Of course, you need an army.

Your task is to create objects: 5 Unit, 3 Knight, 1 General, 1 Doctor.

Don't forget to give them names!

class Unit {    
    String nameUnit;
    
    public Unit(String name){
        nameUnit = name;
    }
}

class Knight {
    String nameKnight;

    public Knight(String name){
        nameKnight = name;
    }
}

class General {
    String nameGeneral;
    
    public General(String name){
        nameGeneral = name;
    }
}

class Doctor {
    String nameDoctor;
    
    public Doctor(String name){
        nameDoctor = name;
    }
}
