➧What is Java and how to learn it?
Hello ! Friends, I am Kundan and today I will tell you some basic details about Java which can be very important for beginners. If you want to program Android, then it is very important to know about JAVA so let's start friends, what is Java?
➧History of java :
The name of this programming language was Oak. U.S.A. In Oak used to be a fairly fruitful tree, Java's icon is also made like a glass-warm enough. In 1995, James Gosling drank tea in the hotel with two of his friends, where the waiter named Java for a brand of coffee, since Gosling changed the name of this programming language from Oak to JAVA. Java was developed to create consumer electronics such as TV, CD, VCR, AC, Refrigerator etc.
The most interesting thing is that in today's time about 3000000+ devices work on JAVA programming language, you might have figured out how popular the Java programming language is.
Java is a featured language. Its important, popular and advance feature is that it is an Object Oriented and Platform independent programming language, which allows Java code to be run or executed on any operating system or on any platform. Java code is case-sensitive, so error generates when there is a slight mistake in it.
To execute Java's program, you have to follow some rules that are called Syntax. If you do not follow Grammar's rules when writing English, then your centence goes wrong. Similarly, programming language also has Syntax. If your programming language's syntax is not correct then your program will generate error.

➧What is Use of Java :
Java Programming Language has the same purpose that code written in Java should run or execute in every computer system, whether it is Mac, windows, linux or any operating system. For example, the code written in c-language or c ++ language can not be executed or executed in other operating systems, but this is not true in Java, it is absolutely wrong to say this for Java.
Java programming language is used to create mobile application, web programming or any software. All Web pages are created in today's time, all go to JAVA Script, the version of any Android operating system, such as KitKat, Lollipop, Nougat, Oreo, are developed from all JAVA programming languages.

➧How to Run and Execute Java Programs:
An Abstract Computing Machine is used to run or execute JAVA's program called Java Virtual Machine, which is also called JVM in the shortcut. Knowing JVM about JAVA program before running or executing is very important, so let us know about JVM from Details.

➧Java Virtual Machine (JVM) :
The Java Virtual Machine is also called a JVM in the short form JVM is a machine that is responsible for the Execute program written by the programmer (also known as source code).
Java Virtual Machine Works between JDK and JRE Java Virtual Machine generates a byte code by compiling the source code with the help of compiler. This is an interpreter in Java to run or execute Java code that runs the java program. To run Java Program, it is necessary to install JDK (Java Development Kit) and JRE (Java Runtime Environment) in the computer system.
As soon as JDK and JRE are installed, JVM installs in your computer system. In a computer system that has JVM installed, you can execute or execute Java byte code in the computer system, so Java is called Platform independent because it can be executed in any computer system. computer system Because of being a JVM, this Java Virtual Code makes it worth running in the operating system.

➧What was the purpose of making java :
You will know people who used to be programming language before, followed a Procedural Structure, then after the concept of Object Oriented Programming Language, this concept changed the entire programming language industry!
I'm glad that object oriented Programming Language is an advanced programming language that follows Java.
You might be thinking that when there had already been so much programming language, then what was the need to make Java? So you guys know Java is an object-oriented programming language and this is a featured language. It has new features provided in it. Its biggest feature is that it is an object-oriented language and it can be run in any computer system. And you people will know that how much is the demand of internet application nowadays.
For example: downloading online images, downloading photos, converting online file to PDF etc. . So this is possible because of Java programming language, so Java language is considered so popular language.
The main purpose of creating Java language was to allow users to access something from anywhere. Like downloading an online movie, staying connected with each other online, downloading online applications, as much as online work is provided by the Java language, therefore Java language was created.
Java language works in conjunction with any other web based language in the internet, which means that java language was created for internet applications and tools development. Compared to any other language, the Java language is very simple and can be easily written and it is also easily executed on the internet. This language is very fast execute compared to any other language.
With Java, Java Script, Jsp (Java Server Pages), Servlet, a powerful web application can also be made with the help of Html and css, as well as help you create a offline program that can be used without internet Can also be executed.

➧Where is the use of JAVA ?
In today's time, more than 3000000+ Devices run from this Java programming language. Java Programming Language is the most commonly used language in the IT industry.
JSP - JSP is Java Server Pages, it is a web web technology that enables Dynamic Web Pages to be created. In JSP, Java code is inserted with HTML Document and JSP tag is used to insert Java code in HTML tags!
Servlet - Java language is also used in the Servlet. In this HTML code with Java code is also inserted. Since Servlet is also a web technology, web pages are also created in it and css is used to give these web pages a good design. css is called cascading style sheet.
Android - android is a platform where mobile applications, mobile software are developed, which are made using the Java language on an Android studio platform. There are mobile applications or mobile running applications, which are saved with .API (Dot API) extension, and these programs are easily run in Android phones. Also Java code is fully used in full application Java Code is created by itself.
AWT - this is a type of window, its full form is Abstract Window Toolkit. As its name suggests, it is a type of window and in this we can add whatever can be done by Java Codding.
Other Electronic Devices - In today's era, the whole thing is becoming digital, as is the case with electronic devices, Java coding is also used.

➧There are some Characteristics of JAVA:
• Simple - Java Programming Language is very simple. It can be easily read and understood. You can easily understand the Concept of Java. Its Concept Objects are on the Oriented Programming Language. To learn this, you will have to learn the Basic Concept of Object Oriented Programming Language only after that you can learn Java language very easily.
• Secure - Java Programming Languag is Secure, security is provided in it. There are security features in it, this is the quality of this language.
• Portable - Because the platform is independent Java language is also portable. You can execute it in any computer system (which should have JDK and JRE installed) in that computer system. Therefore this language is also called Portable Language! This platform is independent language!
• Multiple Threaded - Java is a Multi-Threading Programming Language. Multithrading means that at one time many tasks are done together. This feature is available in Java language that can be done together at one time, so it is also called Multithrade Programming Language. This feature is best for it.
• Dynamic - Java is a Dynamic Programming Language. Dynamic means that if there is a new request every time it changes, it will be updated immediately. This is its best feature. Java is therefore considered a popular language.
For Example: Suppose you do a train search on Google, the time the train is running, the update keeps showing you that it is the feature of dynamic programming language.
• Object Oriented - Java has one of the main features. Object Oriented Programming Language This means that the best programs are created on the object in it. This is its most advanced features. Class of object can be created in the Java programming language, so it is called Object Oriented Programming Language.
