Here is the implementation of some methods of FutureTask in Java:

run method:

I am an engineering student. I have just started Java with the school. We have an exam next week. I have some questions about our preparing project. I'd be very happy IF you could patiently reply to them.

1. Create a Java class called Lane with three fields: o days: a read-only string collection containing the names of days [ How to make a read-only string ]

2. How to put into my index file? ( Normally I learned like <% between those %> but get some error messages..

3. How do I make reservation Array?

   reservations: a collection to store the reservations (e.g. a twodimensional string array or a list of string lists), where the number of rows equals the number of days, and the number of columns equals the number of times. The i. row - j. column cell’s value is „available” if the i-th day’s j-th time interval is still available, or the username of the reserving person otherwise.

4. Last Question ; How to Make such as below the picture.

   Reserved text if the lane is already reserved by someone else for that day and time (different username than the user’s), o a Reserve link if the lane is available, o a Cancel link if the lane is reserved by this user.

newbie question I know, but I can't figure out what the error is in my code for this question. The problem asks to get the sum of all prime numbers below 2,000,000.

I can't figure out why my code works for smaller sets, yet when I wait patiently for my code to finish for 2,000,000 it spits out a wrong answer. 1,179,908,154 in this case.

DISCLAIMER I realize the code I've written is extraordinarily inefficient/wasteful and that I should use the Sieve of Eratosthenes among other things. I'm just trying to figure out why it gives the wrong answer.

I am trying to create simple web app to receive dog adoption applications.

I succesfully run migrations and seeds and by doing so created these two tables:

The problem is that when I try to create new application using GUI, I get the below error:

{"response":"Error in database ForeignKeyViolationError: insert into applications (doggo_name, email, name, phone) values ('Coco', 'sam.do@gmail.com', 'Sam Do', '+12345667') - ER_NO_REFERENCED_ROW_2: Cannot add or update a child row: a foreign key constraint fails (dog_adoption.applications, CONSTRAINT applications_doggo_id_foreign FOREIGN KEY (doggo_id) REFERENCES doggos (id))"}

This is second day I am trying to figure out what is wrong. Please see my code:

MIGRATION FILE:

So my code is basically displaying a message, then telling the user to copy and paste the message and take that as an input to be recalled later.

I am trying to build a database for my website. There are currently three entries with different attributes in my database. I have not created these entries in order, but I have assigned a 'Chapter number' attribute which indicates the order 1,2,3.

I am now trying to inject this using 'context' and 'render' function in my views. I am using the method 'objects.all()' to add all objects to my context. I have a simple Html file where I am inserting the data from the database by looping over (a simple for loop) these added objects.

Now the output that is being generated (naturally) is that it is following the order in which I created the database. I am not sure how I can have the loop run in such a way that I get these chapters in correct order. Thank you for patiently reading my question. Any help will be appreciated.

I've got this multithreading project where I'm supposed to create a simulation of a hotel.

I've got this receptionist struct and their job is to constantly find if there's a free room (done in check_free_rooms method, accommodate_guests is his thread method). If he found a number_to_check_in, is_a_room_ready is set to true and one of guest threads waiting for a room is notified.

Every guest has a field which is a reference to the receptionist (there is only one in the hotel) and the guests are waiting on the receptionist's condition variable receptionist.cv to be notified with the condition of receptionist.is_a_room_ready becoming true. Then, if I understand correctly, one random guest should get a room and the other ones should patiently wait for another notification from the receptionist.

Before you continue to read - the issue has been fixed

Well... this is kinda weird.

I'm working on a web app for some friends. I have a working version uploaded to their hosting, and, suddenly, it stopped working a couple of days ago.

I haven't added anything or changed anything on the server. There is no error, simply the app stopped loading and a blank html page is loaded instead.

I've traced the problem until /vendor/composer/autoload_real.php file.

In the end of the static class inside this file, there is a loop where several other files are being included (actually requested), I've checked that when it tries to request /vendor/laravel/framework/src/Illuminate/Foundation/helpers.php, the system stops. Obviously, I've checked that the file is there, and it isn't been touched.

Well, I'm positive I've didn't changed anything on this part of the app (it's core framework, and I usually don't mess up inside), but just of a sudden it stopped working.

The working copy on my computer just works fine. I've uploaded my copy of helpers.php, but nothing changed.

Anyone had experienced similar issues recently? Anyone has any idea about how to fix it?

EDIT: It's been several days since I could check on this for the last time. Now I've been tracing raw php execution on /vendor/laravel/framework/src/Illuminate/Foundation/helpers.php file. This is, I've started echoing messages and trying to execute just this file, to see where code execution is stopped.

I know this is very crappy debugging, but I haven't access to apache nor I can restart it, and it seems there is no easy way to get an error code without this.

So patiently trying I've reached two points where execution stops on this file:

Creation of factory method

Thank you for taking you time to read this. Basically what I am trying to do is return details on [Issues] that gets pulled from the DB via a stored procedure

There are 2 parameters, [IssueNo] and [LineNo]. When I click on a button the program needs to return the details eg: ItemName, Code etc for each DataGridRow that I select, BUT what it currently does is return the LAST [Issues] details instead of the one I am selecting in the grid.

I know that my stored procedure is correct but somewhere in my C# code the parameters are not getting the value for every row I select. Only ONE and its still the wrong one
