  Deep Understanding of ReentrantLock: Unlocking the Mysteries of Java Concurrent Programming

ReentrantLock introductionReentrantLock is a class in the Java concurrent package, java.util.concurrent.locks, and is an implementation of the Lock interface. As its name suggests, it is a reentrant mutual exclusion lock.A mutual exclusion lock is a synchronization tool used to protect shared resources, ensuring that only one thread can access the resource at a given time. Reentrant means that a thread can acquire the same lock multiple times without causing a deadlock.This lock provides some basic behaviors that are the same as those of the built-in synchronization mechanism. For example, a t...

  Java Interview Questions

Currently there are many articles online which summarize the list of Java interview questions. Some cover lots of basic questions and some cover some specific questions in specific area such as multithreading. In this post, we will not cover the really basic questions, we will cover something different. For basic question, you can read Java Interview Questions。BasicWhat is primitive data type? How many primitive data types in Java? What are they?-- A primitive type is predefined by the language and is named by a reserved keyword. Primitive values do not share state with other ...

  Multithreading interview questions in Java

Multithreading as a widespread programming and execution model allows multiple threads to exist within the context of a single process. These threads share the process' resources but are able to execute independently. The threaded programming model provides developers with a useful abstraction of concurrent execution. However, perhaps the most interesting application of the technology is when it is applied to a single process to enable parallel execution on a multiprocessor system.Many programmers don't know how to use multithreading correctly, and we often get some advice from people regardin...

  Python threads: communication and stopping

A very common doubt developers new to Python have is how to use its threads correctly. Specifically, a large amount of questions on StackOverflow show that people struggle most with two aspects:How to stop / kill a threadHow to safely pass data to a thread and backI already have a blog post touching on these issues right here, but I feel it’s too task-specific for sockets, and a more basic and general post would be appropriate. I assume the reader has a basic familiarity with Python threads, i.e. has at least went over the documentation.So, without further ado, here’s a sample "w...

  C++11 multithreading tutorial

The code for this tutorial is on GitHub: https://github.com/sol-prog/threads.In my previous tutorials I’ve presented some of the newest C++11 additions to the language: regular expressions, raw strings and lambdas.Perhaps one of the biggest change to the language is the addition of multithreading support. Before C++11, it was possible to target multicore computers using OS facilities (pthreads on Unix like systems) or libraries like OpenMP and MPI.This tutorial is meant to get you started with C++11 threads and not to be an exhaustive reference of the standard.Creating and launching a t...

  PHP Multithreading – Faking It

PHP doesn’t really support multi-threading per se but there are ways to do “fake” multithreading. Here’s one I saw in the PHPClasses.org newsletter – Multi-thread Simulation.Note that this class is intedend for use on a webserver, as opposed to running PHP scripts from a command line (or similar). Check the end of this post for some alternatives you can try if you’re using PHP as a stand-alone scripting language.Now, I’m going to be lazy and just copy the description of the class from the project page :)This class can emulate the execution of prog...
