How to recognize taste interface? How should i recognie the taste interface?

1. Create an abstract Drink class with an implemented public void taste() method that displays "Delicious".
2. Create a Wine class that inherits Drink and implements a public String getCelebrationName() method that returns "Birthday".
3. Create a SparklingWine class that inherits Wine and implements a public String getCelebrationName() method that returns "New Year's".
4. Write implementations for the getDeliciousDrink, getWine, and getSparklingWine methods.
5. All the classes must be in separate files.

Requirements:

The abstract Drink class must be in a separate file.
The Drink class must implement a public void taste() method that displays "Delicious".
The Wine class must be in a separate file and be a descendant of the Drink class.
The Wine class must implement a public String getCelebrationName() method that returns "Birthday".
The SparklingWine class must be in a separate file and be a descendant of the Wine class.
The SparklingWine class must implement a public String getCelebrationName() method that returns "New Year's".
The Solution class must implement the getDeliciousDrink() method, which returns a Wine object.
The Solution class must implement the getWine() method, which returns a Wine object.
The Solution class must implement the getSparklingWine() method, which returns a SparklingWine object.

package com.codegym.task.task14.task1410; /* Wine tasting */ public class Solution { public static void main(String[] args) { getDeliciousDrink().taste(); System.out.println(getWine().getCelebrationName()); System.out.println(getBubblyWine().getCelebrationName()); System.out.println(getWine().getCelebrationName()); } public static String getDeliciousDrink() { return wine; } public static String getWine(){ return wine; } public static String BubblyWine(){ return bubblyWine; } }

Your problem is the 3 methods in the solution class. In your code the return value of all three is String, however the requirements specify specific objects that each should return. Also those are not even valid strings that you are returning. Fix the 3 methods to return was the requirements specify, and remove the taste interface as the requirements make no mention of adding one.

reread the requirments carefully. Your Wine and BubblyWine methods are wrong. Bubblywine extends Wine so you need to overide its method. Do the requirments one line at a time and read carefully.
