Java – intuition and design principles

I have a class hierarchy, like this drink – > coffee – > latte

Drinks:

public abstract class Beverage {

    private final String name;
    private final double price;

    Beverage(String name,double price){
        this.name = name;
        this.price = price;
    }

    public String getName() {
        return name;
    }
    public double getPrice() {
        return price;
    }

    public abstract void make();
    }

Coffee:

public abstract class Coffee extends Beverage {

    public Coffee(String name,double price) {
        super(name,price);
    }


    public final void make(){
        grindBeans();
        takeShot();
        frothMilk();
        addCondiments();
    }

    public void grindBeans(){
        System.out.println("Grinding Beans...");
    }

    public void takeShot(){
        System.out.println("Taking Shot....");
    }

    public abstract void frothMilk();
    public abstract void addCondiments();


}

Latte:

public class Latte extends Coffee {

    public Latte() {
        super("Latte",4.0);
    }

    @Override
    public void frothMilk() {
        System.out.println("Frothing milk to create micro foam");

    }

    @Override
    public void addCondiments() {
        // TODO Auto-generated method stub

    }

}

Edit: add sugar to an existing structure Only new codes are displayed

public abstract class Beverage {

private Sugar sugar;

public Sugar getSugar() {
    return sugar;
}

public void setSugar(Sugar sugar) {
    this.sugar = sugar;
}

}

Coffee:

public abstract class Coffee extends Beverage {

public final void make(){
    grindBeans();
    takeShot();
    frothMilk();
    addSugar();
    addCondiments();
}

public void addSugar(){
    Sugar sugar = super.getSugar();
    if(!(sugar instanceof NoSugar)){
        System.out.println("adding " + sugar.getTeaspoon() + " teaspoon sugar");
    }
}

Solution

Although combination and inheritance have many benefits, using the feeling of inheritance is natural (i.e. in a real relationship) without any problems If it is natural, please continue to use it
