What is Java from scratch | technical-arbaab

what is a programming language?

Before going further let us understand first what is a programming language actually so you will have a great understanding of it after a while, a programming language is basically a medium to communicate with a machine for example when two person of two different countries meet, how do they communicate with each other obviously they need a medium suppose one's native language is German and other's is French but they both know English so they can share their thoughts in English because they both can understand it similarly in case of a machine and human being when they try to communicate they both need a medium this lack of communication between a machine and a human being is fulfilled by so called what is known as a programming language, I hope it will help you to understand what actually a programming language is, so now let's move to our main topic which we will definitely not forget is Java as a programming language -

def. programming language-It is a language which is designed to communicate with the machine so that we can direct the machine to follow any instructions given by the user(programmer) by writing some code. (hope it helps)

Java as a programming language

It is a class based, object oriented programming language developed by James Gosling at sun microsystems Inc. with a feature of WORA write once, run everywhere(platform independent java code is converted into byte code which is then run by JVM(java virtual machine which is machine dependent )it was published in 1995 for use while deciding for the name of their programming language, Java developers drinking coffee which was heavily imported from a island called JAVA at that time so they simply name their language JAVA, it is also a general purpose programming language as of 2019 Java was one of the most popular programming language according to GitHub which has reported 9 million developers.

why you learn java?

here are some reason why everyone should start learning java?

• It is one of the most used programming language in the world but you are still worry that how it helps me so let's discuss from example many of the application servers are made from java, all your favorite android stuff are made from java, you can build desktop applications from java, Enterprise level applications like Facebook , Instagram, WhatsApp, LinkedIn, Zomato can also be build from java I doesn't mean not only java but it is also used.

• Many developers thinks of building web applications from java by the use of jsp (Java server pages) and servlets like a birthday wishes application or a pdf to word converter application, movie downloading sites like sdmoviespoint or a site like IMDB which is a popular movie rating site.

•  It prepares you for many open, well paying developer jobs and prepares you for the java interview if you want to prepare just for the interview than core java is sufficient for you or if you wanna go deep than you must implement DSA in java (collection framework) which is most important for any product based company and you must undergo networking in java if you wanna develop some real-world projects for enhancement of the skill, furthermore you can also build beginner to advanced level games in java I 'll recommend you to follow every java playlist of this channel on YouTube https://youtu.be/Hl-zzrqQoSE it will definitely help you to upgrade your skill.

features of Java

•  Object oriented  

• Platform Independent      

• Simple

• Secure 

• Robust

• Multithreaded

• portable

• only requirement of JRE on a machine to run a java program

• High performance

pre-requisite for anyone to learn Java-

 1. Having a general idea of object oriented concepts like if you have already learned languages like c++ it will help you to grab it easily.

 2. A good laptop having at least 4GB of RAM with a good internet connection makes your java learning journey smooth up to some level.

 3. Nothing more take a cup of coffee and start hustling.

Learning Java in 2021 is worth it?

First of all, it is important to remove the myth from friend's mind that there is nothing like this when we are dying(Java). Java has become the most used common language in the banking and IT sector at this time and as many desktop applications is possible in the coming time. Application server, your favorite android stuff please go to all these things and explore it, it is going to be expand in today's date and Java will continue to be used in the future as well, It can also be used on the backend as well for sites like Google, Twitter, Amazon and YouTube so you can say that within the coming 10 years, you are going to live in a very big Java.

Here I will support the statement why java learning is worth it in 2021 by the help of some points (have a look at this🙈)

•  It is always an in-demand programming language because it is most common in web development, app development, big data and especially in distributed systems.

•  It is essential for android development(although Kotlin has become the official language for android according to google ) because of strong memory allocation and high performance.

•  Not only in 2021 but because of the portability feature of java everyone wants to use it (here, we are talking about tech companies they are always in search of experienced java developers) it is a all time favorite language for companies.

•  Because of the quality Java developer community about 45 percent of Stackoverflow 2018 survey respondents use java. It has an extremely large ecosystem of well tested libraries and frameworks for any use case.

•  You can develop a big enterprise level application in java by the use of some top 10 Java frameworks like Spring, Grails, Quarkus, JSF,  GWT, Hibernate, Play.

If you are worrying about what are all these frameworks I have heard this first time, don't worry we are here to clear you everything, Java frameworks are bodies of reusable pre-written code acting as templates that developers can use to create applications by filling in custom code as needed. Frameworks are created to be used over and over so that developers can program applications without the manual overhead of creating everything from scratch.

hope it help you to understood that learning java at any point of time is always worth it(enjoy learning with a quote "If something is important enough, you do it even if the odds are not in your favor." by Elon Musk the ideal for every student not every but for many like mine.
