Java 프레임워크에서 템플릿 메소드 패턴의 이점은 무엇입니까?

abstract class Beverage {
    void prepareRecipe() {
        boilWater();
        brew();
        pourInCup();
        if (customerWantsCondiments()) {
            addCondiments();
        }
    }

    abstract void brew();
    abstract void addCondiments();

    void boilWater() {
        System.out.println("Boiling water...");
    }

    void pourInCup() {
        System.out.println("Pouring into cup...");
    }

    boolean customerWantsCondiments() {
        return true;
    }
}

class Coffee extends Beverage {
    @Override
    void brew() {
        System.out.println("Dripping coffee through filter...");
    }

    @Override
    void addCondiments() {
        System.out.println("Adding sugar and milk...");
    }
}

class Tea extends Beverage {
    @Override
    void brew() {
        System.out.println("Steeping tea bag in hot water...");
    }

    @Override
    void addCondiments() {
        System.out.println("Adding lemon...");
    }
}
