not sure what is wrong

Question about the task

Resolved

@Override public List<JobPosting> getJobPostings(String searchString) { try { Document doc = Jsoup.connect("https://www.linkedin.com/").get(); } catch (IOException e) { e.printStackTrace(); } return Collections.<JobPosting>emptyList(); }

1. On the left in the Project panel, find "External Libraries" at the bottom. Find the examples package in jsoup, and look at the classes in this package.

2. Similar to the implementations in the jsoup examples, connect to the Linkedin URL using the GET method.
This needs to be done in the LinkedinStrategy class's getJobPostings method.
Hint: You'll get a Document object.

3. Set a breakpoint right after the connection. Run the program in debug mode.
Copy the value of document.html() into the clipboard.

4. Create a file with an html extension somewhere in the project's root.
Paste the contents of the clipboard into this file, and format it using Ctrl+Alt+L. IDEA knows how to format HTML.
Hooray! This is the page's HTML code :)

5. Implement equals/hashCode methods in the JobPosting class.
Press Alt+Enter for the equals() and hashCode() methods.

Requirements:

In the LinkedinStrategy class's getJobPostings method, connect to the Linkedin URL using the GET method.
Copy the page's HTML code to a file for further analysis (we won't verify that you have done this).
Use the IDE to generate the equals() and hashCode() methods in the JobPosting class.

package com.codegym.task.task28.task2810; import com.codegym.task.task28.task2810.model.Provider; import com.codegym.task.task28.task2810.model.Strategy; import com.codegym.task.task28.task2810.vo.JobPosting; import java.util.ArrayList; import java.util.Arrays; import java.util.Collections; import java.util.List; public class Aggregator { public static void main(String[] args){ Provider provider = new Provider(new Strategy() { @Override public List<JobPosting> getJobPostings(String searchString) { return Collections.<JobPosting>emptyList(); } }); Controller controller = new Controller(provider); controller.scan(); } }

solution

From part 4: 2. You need to get the web page's source code programmatically. This is done with an HTTP request. You will need a Java HTML Parser. jsoup is a good parser. Let's use it. Find the jsoup website, and download version 1.9.2 of the library and its source files. You don't need to include them in the project! 3. Connect the new libraries: In IDEA, open the "Project Structure" menu item (in the File menu). On the left, select Project Settings -> Libraries. In the upper-right window, click "+". Choose "Java" if the libraries aren't there yet, or choose "Attach Files or Directories" to add jar files to an existing library. In the dialog box, open the folder path from item 2. Then open the folder itself and select all of the *.jar files. I did it and all is ok:

ps jsoup-1.9.2.jar
