kandi X-RAY | check-username Summary
Very often while registering to new websites we try to keep the same username across all the websites. Sometimes the username is available and sometimes it’s not. :(. I created a simple tool using which you can instantly find out if your favorite username is available or not on over 140+ websites.

QUESTION
I am making artificial intelligence bots for my private server. Their names have to be random and unique, so I made a function that retrieves a random string from a website. it takes a second to generate 3 names and adds them to an arraylist. That means in 10 minutes I get 1800 randomly generated strings.
That is a little bit bad since I need a large amount of names in the shortest time possible, so I made multiple threads that generate those 1800 names in less than a minute. But I am not sure whether this is a good practice or not.

Answered 2018-Sep-10 at 18:41I think that this is not a proper way to use threads. Threads are used to handle such things like running GUI and app logic separately so the GUI will not freeze. They are also used to run separated server's and client's thread. You will not actualy benefit from threads in this example. Also, without using executors you are going to run out of memory because of large number of threads (600 is ok but it should be avoided and limited). Use just one thread to not block your main program or do not use threads at all.
In theory, performance would actualy boost on multicore processor but it depends on multiple factors.
