What is Java Programming Language?

The Java Programming Language is a high-level programming language created by Sun Microsystems and released in 1995. Java can run on a number of platforms, such as Windows, Mac OS, and the different versions of UNIX. This tutorial teaches you everything you need to know about Java.

What Is The Use Of Java Programming?

The Java Programming is a powerful programming language that can be used for many things. It is used to make desktop and mobile apps, big data processing systems, embedded systems, and many other things. The company that owns Java, Oracle, says that Java is used on 3 billion devices around the world. This makes Java one of the most popular programming languages.

Java Example Code That Print Hello World

public class helloWorld {

   /* This is my first java program .
    * This will print 'Hello World' as the output
    * This Tutorial is made by Glenn Magada Azuelo
    */

   public static void main(String []args) {
       //System.out.println is a command that can print the output of the program
      System.out.println("Hello World"); // print Hello World
   }
}

You can run this code in your code editor if you already downloaded it to your laptop or PC, but if you don’t, you can download it. Here’s the link. NetBeans IDE, but if you wish to run this code online, we also have an online compiler in Java. Here’s the link. Java Online Compiler

We also put the Java online compiler below. Just scroll down so that you can easily test or execute the source code in order to learn more about Java Programming Language.

Who Is Known As Father Of Java Programming Language?

The father of Java Programming Language is James Gosling OC, also known as “Dr. Java,” is a Canadian computer scientist who was born on May 19, 1955. He is best known as the founder and main designer of the Java programming language.

Why To Learn Java Programming?

This Java Tutorial For Beginners is a MUST for students and working professionals who want to become great Software Engineers, especially if they work in the Software Development domain. I will list some of the most important reasons why you should learn Java Programming:

  • Robust – Java tries to get rid of error-prone situations by putting most of its focus on checking for errors at compile time and at runtime.
  • Portable – Java is portable because it doesn’t depend on the architecture and has no parts of the specification that depend on how it is implemented. Java’s compiler is written in ANSI C, which is a subset of POSIX, and has a clean portability boundary.
  • Architecture-Neutral – With the Java runtime system, the Java compiler makes an object file format that is independent of the architecture of the processor. This means that code that has been compiled can be run on many processors.
  • Secure – With Java’s secure feature, you can build systems that are free of viruses and can’t be changed. Authentication methods are based on public-key encryption.
  • Simple – Java is made so that it is simple to learn. If you know what OOP Java is all about, it will be easy to learn.
  • Platform Independent – When Java is compiled, it is not turned into a platform-specific machine code like C or C++, but rather into byte code that can be used on any platform. This byte code is sent out over the web and read by the Virtual Machine (JVM) on whatever platform it is being run on.
  • Object-Oriented – In Java, everything is called an object. Java is easy to extend because it is based on the Object model.

Java Career Opportunities

Here is a list of jobs you can apply for once you’ve mastered Java.

  • Junior Developer – Every developer will start out as a junior developer. This is the lowest job for a software engineer. The person in this position will be responsible for writing, analyzing, testing, and fixing code. Usually, they are part of teams with mentors and leaders to whom they have to report. At this stage, the developer should focus on learning how the industry works, since it is usually their first job. One must also work on learning new skills to get better at their job and either switch to a better company or get a better position in the same company. This is one of the good Java job opportunities.
  • Senior Developer – A senior developer is someone who is usually in charge of an entire project. They also have to write some code and give reports to the company’s executive officers and managers. In addition to all of this, they are also in charge of helping developers who are new to the company or project they are working on. It is what most people think a developer does.
  • Architect – A Java architect’s job is to design and build the layout of the application.  They divide the different logic layers into groups, which makes it easier for team members to work on different parts of the project. The architect is expected to come up with the best technologies for building the software and to make sure that they all work well together. There are also job postings that are specific to a field and ask the programmer to be good at a certain set of things. Most of the time, these are posted by large companies that don’t need a Java programmer who can do a lot of different things, but rather one who is skilled in a specific area, usually to improve or optimize an existing product.
  • Java Web Developer – This is usually a backend job, and the person in this position is in charge of deploying and maintaining code on the server side. With the popularity of cloud-based systems growing, it helps to know the basics of cloud computing and how to use code in the cloud.
  • Java Android Developer – The developer is in charge of making android apps or adding features to them. This is the most common job ad you’ll see, and it’s also a position that many startups want to fill. Since every business and service now has a mobile app, these jobs won’t go away any time soon.
  • Freelancing – Freelancing is possible because there are a lot of freelance sites on the internet, and it’s easy and quick to connect with clients on sites like LinkedIn. Freelancing can also be a part-time way to make a living with Java. You can gain experience and add to your resume.

Freelance work for Java developers can usually be put into two categories, based on the type of freelancer doing the work.

  1. Coding Job – These are the gigs where you have to work on a project or make a new feature. This is where you write Java code. You could start your career with one of these jobs. Luckily, most of these jobs can be done from home. You can work as a Java app developer or a Java web developer as a freelancer.
  2. Consulting Developers – Most of the time, these companies hire developers who have worked in the field for a few years. When a company needs to get something done quickly, usually to launch or improve a product or feature, they post these jobs. The freelancer is added to the project team, and most of the work is done on-site. The contract ends when the project is done.

Applications Of Java Programming

Java SE 8 is the most recent edition of Java Standard Edition. As Java got better and more people used it, different configurations were made for different types of platforms. J2EE is used for Enterprise Applications and J2ME is used for Mobile Applications.

The new versions of J2 were given new names: Java SE, Java EE, and Java ME. Java will always let you write something once and run it anywhere.

  • Dynamic – Java is thought to be more dynamic than C or C++ because it is made to change with its surroundings. Java programs can store a lot of run-time information that can be used to check and resolve accesses to objects.
  • Distributed – Java was made to work on the internet, which is a distributed system.
  • High Performance – With Just-In-Time compilers, Java makes it possible for programs to run quickly.
  • Interpreted – Java byte code is turned into machine instructions on the fly, and it is not stored anywhere. Since linking is done in small steps and is a light-weight process, the development process is faster and more analytical.
  • Multithreaded – With Java’s multithreaded feature, you can write programs that can do more than one thing at the same time. Because of this design feature, developers can make interactive apps that run smoothly.
