What is Java and its characteristics
What is Java and its characteristics Java is a high-level programming language developed by the Sun Microsystems company. It was primarily designed for developing programs for set-top boxes and hand held devices.But later became a popular language for creating web applications. The Java syntax is similar to C ++, but in reality is an object-oriented programming language.
Today, in this article, we are going to know about Java programming language which is used today on computers, mobile phones and many other places.
This is a language whose name has been heard almost once by everyone in this internet world.
If not heard then you will know today What is Java, how to learn Hindi (What is Java in Hindi)?
Today the demand for Java programming language is increasing worldwide. In view of this demand, today a special class is given to the student for this.
Apart from this, students also join coaching centers by giving them money so that they can get a good knowledge of the language.
In view of this growing demand, today we have prepared this post, in which we will know in detail about what is Java language, how to learn Java language, what is its history, etc.
If you do not know much about it or you want to learn Java language, then read this post carefully till the bottom.
Information of Java in Hindi – JAVA Programming Language in Hindi
Java is an Open Platform computer programming language.
The programming language is because the Java compiler changes the instructions in the program to Bytes Codes.
Which can be run in any computer machine and the size of the primary data type is machin independent.
Meaning that no special type of computer machine is required for this type of data.
It can be used on any computer machine and programs made in the programming language can be run on any computer.
This language is a very portable language compared to other programming languages. A program written in this language is easily copied to any computer.
Apart from this, there is no need to make changes in the hardware, micro processor and software of the system to run it.
Through this we can create programs to be used on the same computer.
As such, programs are made in languages C and C ++.
It is completely based on the program languages C and C ++. But it has some features which are completely different from C and C ++.
You will get to see it in more than 3 million devices worldwide. With which you can guess how popular programming language can be.
It is an object oriental programming language known as High level language.
It is considered high level language because it can be written and read easily.
Today, a language has become a language whose importance is increasing everywhere. This is the reason that today all the people, whether they are students or any other, want to learn this language.
The best thing for the student is that if you learn it well then your chances of getting a job are increased in many places.
Also with the help of this, you can learn coding and make applications 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 learn more about it, then definitely read this post till the bottom.
What is the history of Java – History of JAVA in Hindi
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.
At that time, there was no idea of what to name it and then there was an oak tree outside Gosling’s office, after seeing this oak tree, what was it named oak.
A few days later it was also known as Green.
However, later it was changed to Java. As it is a kind of 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 very popular within a short time and today this programming language started being used in many places like internet, application development, programs etc.
As the technology progressed, so many versions of it 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)
The specialty of Java – Features of JAVA
Today this language is used in many machines around the world. With the introduction of this programming language, there has been a considerable change in the ability to work on computers.
Which means that programming or say coding has become very easy.
Due to its features, this language is used in more than 3 million devices today.
You yourself can understand that when it is being used in more than 3 million devices.
We have explained 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.
- Using this, distributed software can be made, that is, software that works on different computers connected together.
How to learn java – how to learn java
If you want to learn Java programming language, first of all, it is very important to have knowledge of programming language like C, C ++.
If you have good knowledge of C, C ++, then you can easily learn Java programming language.
If you open YouTube, you will find thousands of channels that will teach you this programming language.
You can learn this language from any channel according to your language.
As you know that more and more work is being done online today, you can take help of YouTube to learn Java in such a way.
All 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 take a course in Java and you can easily take advantage of it.
The structure of the program – java program structure in Hindi
When we write a program, it is written step by step in the form of Structure.
Each of its programs has some sections which we can call the structure of the program, which is very important to know about.
That is why we have explained below how to make a program with its help 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
This is the comment line group of the program. Including documents associated with the program such as when and who created the program. It is known.
In the program, you can create a package by any name. To create a package statement, one has to use the example given below. for example
example: – package student;
The important statement is used to add C or C ++, an example of which you can see below.
example: – import calc.add;
If multiple inheritance is to be used in the program then impletement is used.
When Multiple Claas are used in the program, then we use Multiple Class in the Definition section.
The program may have multiple classes, but the stand program must initially have a dot.
main method statement
Today we told you in detail about Java Programming Language which is very important for today’s Internet era.
If you are a student then this post may be most useful for you.
After learning this, you can develop App using Java coding and can also create software. In this way, you can earn good money from it.
Today, people who have knowledge of such developers are in demand around the world.
Today’s post in which we told you What is Java? And what is its history? Apart from this, also told how to learn this programming language?
