What is Java? History of JAVA & Features of JAVA
Java is a high-level programming language that was developed by Sun Microsystems Company. It was primarily designed for developing programs for set-top boxes and handheld devices.
But later it became a popular language for creating web applications. Java syntax is similar to C++, but in reality is an object-oriented programming language.
Today in this article we are going to learn about the Java programming language which is used today on computers, mobile phones and many other places.
This is a language whose name in today’s internet world, almost everyone must have heard it once.
If you do not listen, then today you will know what is Java, how to learn Java?
Today the demand for Java programming language is increasing all over the world. In view of this demand, today a special class is organized for the student for this.
Apart from this, students also join coaching centers by paying money to learn it so that they can have a good knowledge of the language.
In view of this increasing demand, today we have prepared this post, in which we will know in detail one by one about what is Java language, how to learn Java language, what is its history etc.
If you do not have much information about it or if you want to learn Java language, then read this post completely till the bottom.
Introduction to JAVA Programming Language
Java is an open platform computer programming language.
The programming language is because the Java compiler converts the instructions given in the program into Bytes Codes.
Which can be run in any computer machine and the size of the primitive data types is machine independent.
Meaning that this type of data does not require any special type of computer machine.
It can be used on any computer machine and the program made in the programming language can be run on any computer.
This language is quite a portable language as compared to other programming languages. The program written in this language is easily copied in any computer.
Apart from this, there is no need to change the hardware, microprocessor and software of the system to run it.
Through this we can create programs to be used on the same computer.
As program languages are made in C and C++.
It is completely based on the program language C and C++. But it has some such features which are completely different from C and C++.
You will get to see it in more than 3 million devices around the world. With which you can guess how popular programming language it can be.
It is an object oriented programming language which is known as a high level language.
It is considered a high level language because it can be easily written and read.
Today it has become a language whose importance is increasing everywhere. This is the reason that today all the people whether they are students or anyone else want to learn this language.
The best thing for the student is that if you learn it well, then the chances of getting a job in many places increase for this.
Also, you can learn coding and create applications with its help, and there are other places where you can use it.
It is not very difficult to learn it. If you have good knowledge of C, C++ then you can learn this language very easily because Java programming language is the base of C, C++.
If you want to learn Java programming language and want to get more information about it, then definitely read this post completely till the bottom.
History of JAVA
It is an Oriental programming language developed by James Gosling in 1991 through Sun Microsystem.
But its first version jdk1.0 was made public in 1995. Its initial name was oak.
There was no idea what to name it at that time, and then there was an oak tree outside Gosling’s office, seeing this oak tree, it was named Oak.
A few days later it was also known as Green.
However, later it was changed to Java. As it is a language based on C and C++ but it has some object model and some good features from C, C++.
This language was mainly developed for devices like set-top boxes, cable, remote, tv. But it has become quite popular in no time and today this programming language is being used in many places like internet, application development, programs etc.
As the technology progressed, several versions were released, which you can see below:
- JDK Alpha and Beta (1995)
- JDK 1.0 ( 1996)
- JDK 1.1 (1997)
- J2SE 1.2 ( 1998 )
- J2SE 1.3 ( 2000)
- J2SE 1.4 ( 2002)
- J2SE 5.0 ( 2004)
- Java SE 6 ( 2006)
- Java SE 7 (2011)
- Java SE 8 ( 2014)
- Java SE 9 ( 2017)
- Java SE 10 (2018)
Features of JAVA
Today this language is used in many machines all over the world. With the advent of this programming language, there has been a lot of change in the ability to work on the computer.
Which means that programming or coding has become very easy.
Due to its features, today this language is used in more than 3 million devices.
You yourself can understand that when it is being used in more than 3 million devices.
We have told about some important features of this language which you can read below:
- It is a high level language.
- This programming language is a more secure programming language than other programming languages like C, C++.
- It is the most popular programming language around the world and today it is used to make all commercial software.
- Distributed software can be made using this, that is, software that works simultaneously on different computers connected to it.
How to learn JAVA
If you want to learn Java programming language, then first of all you need to have knowledge of programming languages like C, C++.
If you have good knowledge of C, C++ then you can easily learn Java programming language.
Youtube Videos
If you open YouTube and watch, you will find thousands of such channels in it that will teach you this programming language.
You can learn this language from any channel according to your language.
As you know that today more and more work is being done online, so you can take help of YouTube to learn Java.
All the videos of learning Java programming will be found on YouTube, from where you can easily learn Java programming language.
Computer Courses Institution
There are computer institutes in every field which provide all kinds of computer courses to the people.
In computer institutes also you are given the facility to do Java course and you can take advantage of it easily.
Java Program Structure
When we write a program, it is written step by step in the form of structure.
There are some sections in each of its programs, which we can call the structure of the program, which is very important to know about.
That is why we have told about how the program is made with its help below and what is the meaning of the classes used in it.
Some basic structure of Java which is as follows:
- Documentation Section
- Package Statement
- Import Statements
- Interface Statement
- Class Definition
- Main Method Class
Document Section
This is the comment line group of the program. In which documents related to the program such as when and who created the program. It is known.
Package Statement
You can create packages with any name in the program. To create a package statement, it has to be used like the example given below. for example
Example :- package student;
Important Statement
The important statement is used to add C or C++ whose example you can see below.
example :- import calc.add;
Interface Statement
If Multiple Inheritance is to be used in the program then impletement is used.
class definition
When multiple classes are used in the program, then multiple classes are used in the definition section.
Example
class <class_name>
{
data member ;
member method;
}
Main Class
The program can have many classes but stand program must have a dot at the beginning.
Example
{
main method statement
}
In short
Today we told you in detail about the Java programming language, which is very important for today’s internet age.
If you are a student then this post can be most useful for you.
After learning this, you can develop apps and create software using Java coding. In this way you can earn good money from it.
There is a demand for people having knowledge of such developer all over the world today.
