Stuck with 2 requirements not passing. This big task is toughhh

Question about the task

Aggregator (part 13)

Java Collections, Level 8, Lesson 15

Under discussion

From the 5 people that actually passed this, can you give me a small hint? Thank you!!

Check it out — there are two new files in the view package:
jobPostings.html (you will write data here),
backup.html (a copy of jobPostings.html for data recovery if the data in jobPostings.html is erased somehow).

Hover over and right-click jobPostings.html in the project tree on the left. Then click "Open in Browser".
This way you will see the result of your parsing.

It's time to display the job postings.
1. In the HtmlView class's update method, implement the following:
1.1. create a new body for jobPostings.html, which will hold the job postings,
1.2. write the updated body to the jobPostings.html file,
1.3. All exceptions must be handled in this method. Display a stack trace if an exception occurs.

2. To implement item 1, create two empty private methods:
String getUpdatedFileContents(List<JobPosting>) and void updateFile(String),
We will implement them in future tasks.

3. To get to the jobPostings.html file, create a relative path to it.
In the HtmlView class, create a private final String filePath field and assign it the relative path to jobPostings.html.
The path must be relative to the project's root.
Create the path dynamically using this.getClass().GetPackage() and the "/" separator.
Hint: the path must begin with "./".

Requirements:

In the HtmlView class, create an empty private String getUpdatedFileContents(List<JobPosting>) method.
In the HtmlView class, create an empty private void updateFile(String) method.
Using the created methods, implement the update method in accordance with the task conditions.
In the HtmlView class, create a private final String filePath field and assign it the relative path to jobPostings.html.

<!DOCTYPE html> <html lang="en"> <head> <meta charset="UTF-8"> <title>Title</title> </head> <body> </body> </html>

You solved it in 27 attempts. Exactly… I was trying to pass this task with parsing html File, handling exceptions, it was enough to simply pass it with just like Seb said:

@Override
public void update(List<JobPosting> jobPostings) {
    updateFile(getUpdatedFileContents(jobPostings));
}

Here is the right one: private final String filePath = "./4.JavaCollections/src/" + this.getClass().getPackage().getName().replaceAll("\\.", "/") + "/jobPostings.html"; I was struggling with it several time, because I was adding also "view" directory.

Check your filePath. What will it print out? Replace '.' with '/' If this is not enough, you might also need to add a piece of the path before this.getClass() - say filePath = "./4.JavaCollections/src" + this.getClass()... Adjust your update method so that it pretty much only contains two stub methods. updateFile(getUpdateFileContents(jobPostings)); I hope that's it. ;-)
