i have a client-server application. client and server should communicate via
tcp sockets. ok, so i use Sockets, PrintWriter and BufferedReader. the
problem is that: both client and server will send each other multiple lines
(using PrintWriter.println()) at a time, and i don't know how many lines
each of them will send. this wouldn't be a problem if a sender could end his
turn with a pre-defined character or string (e.g. "\n", "bye" or...

Hi. I have a file using \n as line-separator. There are also
occurrences of \r in the file, but I don't want the
BufferedReader.readLine() to consider those as EOL.
Apart from stripping all \r from the file before processing it, what
good options are there? Do I have to inspect the data char-by-char, or
is there a better way?
Thanks,

I want to know which one will be faster randomAccessFile or Bufferedeader. I am reading a file about 18 MB. For that using randomAccessFile i will read from the beginning of the file the first time and i will get the position of file pointer depending on the line's data and after that i will start reading from the position of file pointer. this will happen for each call of one method that i wrote..... initially i used BufferedReader but it was...

Hi all,
I'm struggling with a challenge on new learnings about reading and writing from a txt file.
Now I have just learnt about the Scanner class and i can usedelimiter (",") to create tokens. But what if the txt file has a heading before each token on the first line, how do you check that what you want it to say and what it does say are true and therefore go on to next line which are where the tokens are. I do admit this is homework but...

Hello folks,
I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>".
The problem is that using the GNU compilers, it seems that the internal comparison operator "<=>" tries to promote arguments from unsigned to signed.
This is as boiled down as I can make it.
Here is my compilation command:
g++-12 -std=c++20 -Wnarrowing bit_field.cpp
Here is the code in...

Let's talk about the concept of autonomous AI software engineers and no-code agents. These AIs are designed to manage the entire lifecycle of a software development project—planning, coding, testing, and deployment—without human intervention. Imagine an AI that can take a project description, break it down, write the code, debug it, and then launch it, all on its own....
Now, this would greatly impact the work of software developers. The idea...

I succeeded, with both firewalls in the same network. But I'm wondering if it's possible to do the same thing, with 2 Pfsense firewalls...
