Java Thread Programming shows you how to take full advantage of Java's thread facilities: when to use threads to increase your program's efficiency, how to use them effectively, and how to avoid common mistakes. There is thorough coverage of the Thread API, ThreadGroup classes, the Runnable interface, and the synchronized operator. Extensive, complete, code examples show programmers the details of creating and managing threads in real-world applications.

An Advanced Java Tutorial aimed towards the Developer Who Already has Learned the Fundamentals of Java Programming.

This article is the first in a four-part Java 101 series exploring Java threads. Although you might think threading in Java would be challenging to grasp, I intend to show you that threads are easy to understand. In this article, I introduce you to Java threads and runnables. In subsequent articles, we'll explore synchronization (via locks), synchronization problems (such as deadlock), the wait/notify mechanism, scheduling (with and without priority), thread interruption, timers, volatility, thread groups, and thread local variables.

Note that this article (part of the JavaWorld archives) was updated with new code listings and downloadable source code in May 2013.

Conceptually, the notion of a thread is not difficult to grasp: it's an independent path of execution through program code. When multiple threads execute, one thread's path through the same code usually differs from the others. For example, suppose one thread executes the byte code equivalent of an if-else statement's if part, while another thread executes the byte code equivalent of the else part. How does the JVM keep track of each thread's execution? The JVM gives each thread its own method-call stack. In addition to tracking the current byte code instruction, the method-call stack tracks local variables, parameters the JVM passes to a method, and the method's return value.

Today I want to introduce the topic of Java multithreading to you. This is a bit of an advanced topic, so if you are not familiar with Java programming, I would recommend starting with the basics . If you have been around the Java programming block and have not yet tried your hand at multithreading, then that’s great! Let’s get started.

In Java, a Thread is essentially the Object that represents one piece of work. When you start your application and it starts to run, Java has “spawned” (created) a Thread and this Thread is what will carry out the work that your application is meant to do. What’s interesting to note, is that one Thread can only do one particular task at a time. So that would mean it’s a bit of a bottleneck if your entire application just works off of one Thread right? Right!

Java multithreading allows you to do multiple tasks at the same time . This is possible because modern day computers have multiple CPUs (CPUs are the brain of your computer, and it has a bunch!). One CPU can work on one Thread at a time (unless your CPUs have hyper-threading, in which case it can handle two at a time). So this means that if your computer has 4 CPUs with hyper-threading technologies, your code could potentially handle 8 Thread s at the same time. Neat!

Welcome to the first part of my Java 8 Concurrency tutorial. This guide teaches you concurrent programming in Java 8 with easily understood code examples. It's the first part out of a series of tutorials covering the Java Concurrency API. In the next 15 min you learn how to execute code in parallel via threads, tasks and executor services.

The Concurrency API was first introduced with the release of Java 5 and then progressively enhanced with every new Java release. The majority of concepts shown in this article also work in older versions of Java. However my code samples focus on Java 8 and make heavy use of lambda expressions and other new features. If you're not yet familiar with lambdas I recommend reading my Java 8 Tutorial first.

All modern operating systems support concurrency both via processes and threads . Processes are instances of programs which typically run independent to each other, e.g. if you start a java program the operating system spawns a new process which runs in parallel to other programs. Inside those processes we can utilize threads to execute code concurrently, so we can make the most out of the available cores of the CPU.
