Java Programming - Things to know!
Introduction to the language: Java is basically a general-purpose programming language, it is a class-based, and object-oriented programming language which is designed to have lesser implementation dependencies. Java is more like a computing platform for application development. It is more faster, more secure, and reliable and hence it is widely used for developing applications which is both mobile & laptop compatible, data centres, game consoles, etc.
History of Java Programming Language: Like I already mentioned, Java is an object-oriented programming language which was originally developed by James Gosling in the year 1990s. The team ’s initially idea was to work on a project which can be used to develop a language that can be used for the digital devices such as the set-top boxes, television, etc. Originally, C++ was considered to use as the major programming language but later on, the idea was rejected for several reasons.
Gosling in his thinking process looked to alter and expand C++, however before actually surrendered that for making another stage called as the Green. James Gosling and his team called their project as the “GreenTalk” and the file extension to save and work on this file was originally decided to be .gt and later became to be known as the “OAK”.
Why “Oak”?
The name Oak was used by the Gosling after an oak tree which was there outside his office. Also, Oak also refers solidarity image and is also picked as a national trees of various nations such as the U.S.A., France, Germany, Romania, etc. But later on after a little more thinking changed the name to “JAVA” as it was already a trademark by Oak Technologies.
“JAVA”
Gosling and his team after all the brainstorming sessions, they came up with several names which included: JAVA, and other names such as DNA, SILK, RUBY, etc.
Java was the name that was decided after so many discussions since it was a little unique. The name Java originated from a sort of espresso bean, Java. Gosling ended up with this name while having a coffee near his office.
Java was created by keeping various aspects in mind like Robust, Portable, Platform Independent, High Performance, Multithread, etc. and was also called one of the Ten Best Products of 1995 by the TIME MAGAZINE.
Currently, Java is used for creating tools/applications such as the internet programming, mobile devices, games, e-business solutions, etc. Java language also experienced a few changes since JDK 1.0 just as various other augmentations in the classes and packages to the standard library. In addition to this, the language changes, that to more sensational changes made to the Java Class Library throughout the years, which was evolved and developed from a couple of hundred classes in JDK 1.0 to more than three thousand in J2SE 5.
Java Version History: There were so many java versions that have been released till now. The current version release of Java is Java SE 10. Others are as follows:
JDK Alpha and Beta (1995)
JDK 1.0 (23rd Jan 1996)
JDK 1.1 (19th Feb 1997)
J2SE 1.2 (8th Dec 1998)
J2SE 1.3 (8th May 2000)
J2SE 1.4 (6th Feb 2002)
J2SE 5.0 (30th Sep 2004)
Java SE 6 (11th Dec 2006)
Java SE 7 (28th July 2011)
Java SE 8 (18th Mar 2014)
Java SE 9 (21st Sep 2017)
Java SE 10 (20th Mar 2018)
Java SE 11 (September 2018)
Java SE 12 (March 2019)
Java SE 13 (September 2019)
Java SE 14 (Mar 2020)
Java SE 15 (September 2020)
Java SE 16 (Mar 2021)
Java SE 17 (September 2021)
Java SE 18 (March 2022)
Since Java SE 8 release, it is understood that the Oracle corporation had started following a pattern in which every even version would be released in the month of March and an odd versions to be released in September month.
Features of Java: The primary or the sole objective of Java programming is to make it portable, simple and a more secure programming language. Apart from this, Java has some excellent features which comes handy and makes the language more and more popular.
Some of the features of Java programming language are as follows:
Java comes in with a very simple syntax and easy to learn concept.
Like we discussed already, it is an object oriented programming language.
Java is more secured, we can develop virus-free systems
The language is stronger than any other programming i.e., it used a very strong memory management technique also it lacks the pointers which helps to avoid the security problems.
Java is more portable as it allows the bytecode to be used anywhere and in any platform. It does not require any other implementation process.
This programming language is much faster when compared to any other traditional interpreted programming languages because the byte code is pretty similar to the native code. This makes the performance more and more better.
Java is also a dynamic language. It supports everything that is required for the dynamic loading of the classes in other words, the classes are loaded on demand. It also supports the functions from other languages such as C and C++.
Advantages & Disadvantages of Java?
Advantages:
Java is very simple
Java is an object oriented programming language
Java is cheap and economical to maintain
It also provides an efficient memory allocation strategy.
Java is a platform independent programming language i.e., WORA (Write Once Run Anywhere)
Java supports portability feature
Java also acts as a distributed language.
Disadvantages:
Java lacks the back-up facility
Java is a very slow and has a poor performance
Java requires a significant storage space
Java requires a lot of coding for a very simple one liner outcome
We cannot expect a beautiful outcome, look or a design using Java Programming
These are some of the advantages and disadvantages of Java programming.
Alternatives to Java Programming: Alternatives to Java that are most analogous and used for similar purposes apart from Java are C#, .Net etc.
Conclusion: Java has been consistently holding the top spot in various research organisations among all the other programming languages. Though new programming languages are coming up day-by-day, java does not loose its spot. Just like other programming languages, Java to has its hooks and crooks but still it is managing to rule over the other programming languages for as long as 20years.
