Put your blocking call on a new thread and if the time expires you just move on, leaving that thread hanging. In that case you should make sure the thread is set to be a Daemon thread. This way the thread will not stop your application from terminating. Use non blocking Java APIs. So for network for example, use NIO2 and use the non blocking ...

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.
Apr 30, 2024 · We can call this method at the beginning and at the end of the function and by the difference we measure the time taken by the function. 1. Using System.nanoTime() The most common approach to calculating execution time is by utilizing the System.nanoTime() method, that provides a high-resolution timer. Here’s how you can use it: Java
Aug 28, 2023 · The callback function supplied to the method setTimeout() is added to the queue after the timeout expires. setTimeout(function, milliseconds); Here, milliseconds is the amount of time it takes for a function to be executed and function is a block of code; Syntax. Example: // Display a text using setTimeout method function displayText()
Jun 22, 2014 · I would have a look at using ExecutorService in Java for this and have the class with the functionality you want to time out implement runnable - so using Java's threading capabilities to help you out. You should be able to timeout the thread using the following code: ExecutorService executor = Executors.newSingleThreadExecutor(); executor ...
Jun 28, 2024 · A timeout function is frequently used to run after a specified amount of time. Sometimes, we need to run function with schedule. ... timeout function in java we can use javafx.animation ...
