Find out how to use multithreading in Java to process multiple tasks concurrently. Discover all you need to know about understanding and implementing multithreading!

In this article, CloudVandana will share a comprehensive guide to understanding multithreading in Java.

It is an important concept in Java that allows a program to execute multiple tasks concurrently. It is used to improve application performance and make the most use of a system’s computing resources. This article will explore how the process works and how it can be implemented in Java.

What is Multithreading?

It is a process by which multiple tasks can be executed concurrently in a single program. This process divides the program into smaller parts that are independent of one another, allowing them to be processed simultaneously. By utilizing this process, these applications are able to utilize the computing resources available on modern computers efficiently.

Why Use Multithreading in Java?

Multithreading in Java offers several advantages. Allowing multiple tasks to be processed in parallel increases the program’s overall efficiency. This way, it is possible to take full advantage of the computing power available on modern machines with multiple cores. Furthermore, the process allows for smoother UI animations and more responsive user interfaces, as processes can be handled faster and with less lag.

How to Create and Run a Thread in Java

If you want to use this process, then you first need to create and launch a thread. To do this, Java provides the Thread class to create and control threads. The basic outline of creating a Thread is as such: Create an instance of the Thread class, passing in a Runnable object that defines what should be done when the thread runs. Finally, call start() on the instance of your Thread to launch it.

Implementing Synchronization

Synchronization is a feature of this feature that ensures that only one thread can access or manipulate a resource or data at any given time. This helps prevent race conditions and other thread-related issues. To use synchronization, you create a synchronized block that will only allow one thread to enter it at a time. Once the thread completes its operations, the block is released so that another thread can acquire the lock and access it.

Using Callable and Future for Interacting with Running Thread

Callable and Future are two classes used for interacting with threads that are already running. Callable is a method that returns an object, while Future is an interface that provides methods to check if the computation is complete and to retrieve the result of the computation. These classes make it easier to manage the lifecycle of threads and obtain results from them.
