在 Java 中访问不同类的静态成员时避免代码重复

Question

I'm writing an abstract class and have some sub-classes extend it. I have the exact same method with the same implementation in the sub-classes, and I'm wondering if there's a way to avoid the code duplication. The problem is that although the code is completely identical in every class, it uses a static variable of the class. Is there a way to have the method written only once (in the abstract class, for example) and have the method access the static member " NAME " from the class type of the current object?

In other words, is there a way to implement the method getName() only once, and return the NAME static variable of the current type of class?

public abstract class Car {
    public abstract String getName();
}

public class Bus extends car{
    
    private static final String NAME = "Bus a Bus A";
    
    public String getName() {
        return Bus.NAME;
    }
}

public class Taxi extends car{

    private static final String NAME = "TAXiiii";

    public String getName() {
        return Taxi.NAME;
    }
}

public class Motor extends car{

    private static final String NAME = "motor hehe";

    public String getName() {
        return Motor.NAME;
    }
}

Why not simply pass the name to the super constructor? Although this removes the need for Car to be abstract , because you can simply return the name from its getName method instead.

public class Car {
    private final String name;
    
    public Car(String name) {
        this.name = name;
    }

    public String getName() {
        return name;
    }
}

public class Bus extends Car {

    private static final String NAME = "Bus a Bus A";

    public Bus() {
        super(NAME);
    }
}

public class Taxi extends Car {

    private static final String NAME = "TAXiiii";

    public Taxi() {
        super(NAME);
    }
}


public class Motor extends Car {

    private static final String NAME = "motor hehe";

    public Motor() {
        super(NAME);
    }
}
