Let us first understand what Programming is. Is it an art or science or is it a mixture of both?
The mixture of both gives birth to the word “Craft”. Programming is a craft work. It is usually an activity that is done to provide with some useful and intangible artifact.
As the basic fundamental goes on, a Programming language uses some of the science and mathematics.
To create a complicated code, it passionately requires skill and ingenuity. In this world of coding, computer programming comprises many languages from all over the world.
Some of the common programming languages are C, C++, Python, Java, HTML and many more.
In the following points, we are going to mention one such important language of coding that is expressively designed and widely used all throughout the internet environment popularly known as Java.
Let us have a brief view about the language:
Java is one of the most popular programming languages used for Android smartphone applications.
The java application was basically designed as an alternative for the C++ programming language but its utility has been converted to simpler use.
A java developer usually creates applications that usually run on a single computer or it can be distributed among servers and clients in a specific network. The Java application can also be used to build a small module as a part of a certain webpage.
Java once get formulated can be achieved and executed from almost every corner of the world and it makes sure that the user implements the doubtful codes in a safe and sound atmosphere.
Java is always given the first priority to the aspiring students who are looking for the network-based uses.
Java was developed by James Gosling and released in 1995 as a core and competent component of Sun Microsystems’ Java platform. In May 2007, along with the specifications and stipulations of the Java community process, the Sun Microsystems had licensed most of the technologies under the General public License.
Java has an interesting history! All credits to the inventor!
The history of the Java application is indeed interesting!
Java was designed exclusively for the interactive television but it was so advanced in its technological standard that the Java team members and the developers initiated the project for developing mainly for digital devices.
These digital devices mainly include set-top boxes and televisions.
The Java programming language was also suited for internet programming and in the later years, the technology was incorporated by Netscape.
The Java language was initiated and founded by James Gosling, Mike Sheridan, and Patrick Naughton in June 1991. This small team of the engineers was known as Green Team.
It was first named as OAK after the oak tree that stood outside Gosling’s office and in 1995 it was changed to JAVA.
The first public execution of Java was carried out in the year 1996. It usually allowed network and the file-access restrictions.
Sooner on it became very popular as many other web browsers all merged together to run the java applets.
What were the major principles in the creation of the Java Language?
- It should be secure and robust.
- It must be portable and neutral to architecture.
- It should carry out its executions with high standard performance.
- It should be dynamic in nature.
- It should focus on more object-oriented and it should be simple in nature.
What are the versions of Java?
We all know that Java is a high-level programming language. It is actually envisioned to allow the Java application developers to “Write once, run anywhere” (WORA), which means that the compiled Java code can actually connect on all platforms that mainly support the application.
So, let us move on to the definite versions of Java
Java SE 8(2014)
Java SE 7- Dolphin
Java SE 6- Mustang
J2SE version 5.0- Tiger
JESE version 1.4- Merlin
J2SE version 1.3- Kestrel
J2SE version 1.2- Playground
JDK version 1.1- Abigail (Version 1.1.6), Brutus (Version 1.1.7), Chelsea (1.1.8)
JDK version 1.0- OAK
Do we know how Java executes?
The programs are written for Java usually run on any sort of combination of hardware and the operating system with sufficient time support.
This is accomplished by collecting the Java Language code to the transitional representation known as Java bytecode.
The Java bytecode is generally instigated by a Virtual machine for the host hardware.
The utility of the universal bytecode makes the porting simple. The interpretation of the bytecode to the machine instructions tend to run in a slower process.
After the bytecode gets loaded by the loader it is inspected by the bytecode verifier whose job is to check:
- Variables are mostly initialized.
- It is made sure that the run time stack does not overflow.
- There are method calls which match the types of references regarding the object.
- There should not be any violation of the rules while accessing private data.
Finally we come to the final stage by the Java programming.
Using a Just-In-Time compiler, the native code is executed by the hardware.
The JIT compiler compiles the bytecode into the native machine code, thereby improving the performance of the Java applications during the run time.
Students need the motivation to work with Java application!
“Everybody in this country should learn to program a computer because it teaches you how to think.” – Steve Jobs.
A working student even if he is not from the Computer science background can learn Java!
Oh yes! The students cannot learn Java in a few days! Motivation and hard work is always prioritized before anything else in order to grasp the idea of the programming language.
Apart from that, learning Java with assignments4u.com helps the students to reach their pillars of success as he might establish the following steps:
- Very good communication
- Attitude of solving difficult problems.
- Creativeness with sheer analytical skills.
- Work with specified deadlines
- Fluent in English speaking
So, people! Keep calm and enjoy the process of learning as Java is gradually evolving all the time. Know your techniques very well so that you become more efficient with this popular programming language.
