WTF? The same code like solution

Question about the task

Aggregator (part 5)

Java Collections, Level 8, Lesson 15

Resolved

Three red buttons? What the hell is going on here? I think this project was build untidy...

1. Add a getJobPostings(String searchString) method to the interface. It will return a list of job postings.

2. Correct the errors in the LinkedinStrategy class.

3. Return to the Provider class's getJavaJobPostings method. Implement it assuming that all the data is adequate.

4. Let's try to run our program and see how it works.
In the main method, write controller.scan() instead of outputting to the screen;
Accept IDEA's suggestion and create a method.
Inside the method, go through all of the providers and collect all their job postings and add them to the list. Display the number of job postings.

5. Fix the NullPointerException (NPE) if one occurs (add a stub).

Requirements:

Add the getJobPostings(String searchString) method to the Strategy interface.
Update the LinkedinStrategy class so that there are no errors.
Implement the getJavaJobPostings method in the Provider class.
In the main method, add a call to controller.scan() instead of outputting to the screen. Implement this method as outlined in the task conditions.
The main method must not throw a NullPointerException. Put stubs in the required places.

package com.codegym.task.task28.task2810; import com.codegym.task.task28.task2810.model.LinkedinStrategy; import com.codegym.task.task28.task2810.model.Provider; public class Aggregator { public static void main(String[] args) { Provider provider = new Provider(new LinkedinStrategy()); Controller controller = new Controller(provider); controller.scan(); } }

Xd It's not Validator's fault after all, and the only person who built this project untidily is me...

You won't believe how many situations I already had (coding related) where I wanted to bang my head against the table

I can trust you had.. I really appreciate every person which are programmer or learning this. I still don't know after above year learning if this is for me.
