Java Concurrency: Thread Life Cycle

In the Java language, multithreading is driven by the core concept of a Thread. During their lifecycle, threads go through various stages.

Understanding Thread Life Cycle and the Thread States are very important when you are working with multithreaded programming.

To understand thread states and when the thread is moving between these states we will use a diagram:

On this diagram, you can see all the possible states of a Thread and conditions when these states are changing. To make it more clear we will go through all these states. But before let’s check what each state means.

How to Install OpenJDK 11 on CentOS 8

What is OpenJDK?

OpenJDk or Open Java Development Kit is a free, open-source framework of the Java Platform, Standard Edition (or Java SE). It contains the virtual machine, the Java Class Library, and the Java compiler. The difference between the Oracle OpenJDK and Oracle JDK is that OpenJDK is a source code reference point for the open-source model. Simultaneously, the Oracle JDK is a continuation or advanced model of the OpenJDK, which is not open source and requires a license to use.

In this article, we will be installing OpenJDK on Centos 8.

Going Beyond Java 8: Local Variable Type Inference (var) - DZone Java

According to some surveys, such as JetBrains’s great survey, Java 8 is currently the most used version of Java, despite being a 2014 release.

What you are reading is one in a series of articles titled ‘Going beyond Java 8,’ inspired by the contents of my book, Java for Aliens. These articles will guide you step-by-step through the most important features introduced to the language, starting from version 9. The aim is to make you aware of how important it is to move forward from Java 8, explaining the enormous advantages that the latest versions of the language offer.

In this article, we will talk about the most important new feature introduced with Java 10. Officially called local variable type inference, this feature is better known as the **introduction of the word **var. Despite the complicated name, it is actually quite a simple feature to use. However, some observations need to be made before we can see the impact that the introduction of the word var has on other pre-existing characteristics.

Threads In Java Part 2

Understand The Creation and Prevention

Following My Previous Blog on Threads in java, Let’s Continue to explore threads deeper by understanding more of their concepts.

How to prevent thread executions

We can prevent thread execution by using the following three methods

  1. yield()
  2. join()
  3. sleep()

1) yield() :-

yield() is present in thread class with the following declaration

Public static native void yield()

If a thread wants to give the change to another waiting thread of the same priority then that thread call yield method,

If a thread is executing and one higher priority thread comes then that executing thread will be stopped and immediately a higher priority thread will get a chance.

How To Create a Thread in Java? | Multithreading in Java

In this article, we will take a look at threading in Java and explore the mechanisms that make threading possible.

Threading In Java

The threading feature in Java is a lightweight sub-process. It is considered to be the smallest unit of processing. It is a means to achieve multitasking in a program. It is a useful feature when it comes to games, animation, etc.

Java has in-built support for creating threads and multi-threads. This is a clever approach to minimizing inefficiencies and lugging by optimum utilisation of CPU space. In Java, this can be done in two ways:

  1. Extend Thread Class, or
  2. Implement Runnable Interface

When more than one threads are executed simultaneously, it is called multithreading. This essentially allows multiple parts of a program to run concurrently, each part of a thread and each thread follows a distinct path to execution.

Threads utilise shared memory space; memory is not allocated to each part, resulting in maximum usage of CPU. Further, changing contexts doesn’t take up much time. However, too many threads could engage your CPU in context-swiching and your execution could get delayed.
