Nov 23, 2010 · Assume the work in the loop takes 7 seconds to complete. After one run you're at 7 seconds, then 14... until you have completed 8 iterations, for a total of 56 seconds. The check will succeed (because you are under 60s) but then the calculations will take 7 seconds. By the time the check is done again, you're at 63 seconds. That's 5% over time.

In this article, we’ll learn how we can end a long-running execution after a certain time. We’ll explore the various solutions to this problem. Also, we’ll cover some of their pitfalls.
Imagine that we’re processing a bunch of items in a loop, such as some details of the product items in an e-commerce application, but that it may not be necessary to complete all the items. In fact, we’d want to process only up to a certain time, and after that, we want to stop the execution and show whatever the list has processed up to that time....
Here, we’ll use a separate thread to perform the long-running operations. The main thread will send an interrupt signal to the worker thread on timeout. If the worker thread is still alive, it’ll catch the signal and stop its execution. If the worker finishes before the timeout, it’ll have no impact on the worker thread. Let’s take a look at the wo...
There’s no guarantee that the execution is stopped after a certain time. The main reason is that not all blocking methods are interruptible. In fact, there are only a few well-defined methods that are interruptible. So, if a thread is interrupted and a flag is set, nothing else will happen until it reaches one of these interruptible methods. For ex...
In the previous section, we highlighted the importance of having interruptible methods to stop the execution as soon as possible. Therefore, our code needs to consider this expectation from a design perspective. Imagine we have a long-running task to execute, and we need to make sure it doesn’t take more time than the specified. Also, suppose the t...
In this tutorial, we’ve learned various techniques for stopping the execution after a given time, along with the pros and cons of each. The complete source code can be found over on GitHub.
Aug 24, 2016 · In effect, Minecraft keeps ticking right along, but some sequence of your actions is spread out over time. That's what tick handlers do. Your logic wakes up, looks at the world and its own preserved thoughts, increments tick counters, make decisions, take actions, stores (or wipes) data for next time, and then exits to allow the rest of the program to continue.
/execute store result score #time time run time query daytime. Repeat this, it store a score that represent daytime in tick. 1000 is day, 18000 is midnight, 13000 is night, and 6000 is noon. All you need is detect the score and run commands /execute if score #time time matches 6666 run tellraw @a "here"

Unit postfixes for minutes, hours etc. do not exist. The in-game days unit is not affected by sleeping or /time. If you have changed your mind, you can abort a scheduled function execution like this: /schedule clear abc:test If you want to schedule multiple executions, you can use append instead of replace.

Jan 8, 2024 · In this article, we’ve explored multiple programmatic ways to stop the execution of further code in Java programs. To halt a program, we can use System.exit(0) for immediate termination. Alternatively, return and break statements help to exit particular methods or loops, while exceptions allow for the interruption of code execution.
