What's wrong?

Question about the task

Online store for jeans

Java Multithreading, Level 4, Lesson 6

Resolved

What's wrong? When I test, everything is ok in my opinion. However, it does not want to pass the last condition.

1. Create 2 interfaces in separate files:
1.1) Item with int getId(), double getPrice(), and String getTM() methods
1.2) Jeans extends Item with the int getLength() and int getSize() methods

2. In the Util class, add the missing Java code to the getAllJeans method:
2.1) figure out what the Util class's getAllJeans method already has
2.2) create an abstract AbstractJeans class using the Jeans interface with one abstract method, and implement the remaining methods
2.3) create Levis and Armani classes using AbstractJeans, and implement the remaining method
2.4) Implement the toString() method in the AbstractJeans class (you can use Alt+Insert -> toString())
2.5) the output of the AbstractJeans class's toString method should start with the name of the subclass, for example, Levis{id=1, length=34, size=6, price=150.0}

Requirements:

The Item interface must be in a separate file.
The Jeans interface must extend the Item interface and be created in a separate file.
The Item interface must include all the methods listed in the task conditions.
The Jeans class must include all the methods listed in the task conditions.
A local abstract AbstractJeans class that supports the Jeans interface must be created in the Util class's getAllJeans method.
A local Levis class that inherits the AbstractJeans class must be created in the Util class's getAllJeans method.
A local Armani class that inherits the AbstractJeans class must be created in the Util class's getAllJeans method.
The AbstractJeans class must implement a toString() method whose output starts with name of the subclass.

package com.codegym.task.task24.task2409; import java.util.List; /* Online store for jeans */ public class Solution { public static List<Jeans> allJeans = Util.getAllJeans(); public static void main(String[] args) { for (Jeans jeans : allJeans) { System.out.println(jeans); } } }

Brilliant !!! The error is in the task body. In the enum class :) No matter how many times the task improves, the validation of the last condition will always go wrong. Instead of Levi's, there is to be Levis. They made this mistake on purpose? You are super!! :) :)

solution

Take into consideration this code:

enum Company {
    Levis ("Levi's"),
    Armani("Armani"),
    Lucky("Lucky"),
    CalvinKlein("Calvin Klein");

    final String fullName;
    Company(String name)
    {
        this.fullName = name;
    }
}
public class Solution {

    public static void main(String[] args) {
        System.out.println(Company.Levis.toString());
        System.out.println(Company.Levis.fullName);
    }
}

Run it in a test and compare it with the example output in the conditions of: Levis{id=1, length=34, size=6, price=150.0}
