Java is a popular general-purpose programming language and computing platform. Qurbani moves full mp3mp3 song download. It is fast, reliable, and secure. According to Oracle, the company that owns Java, Java runs on 3 billion devices worldwide.

Considering the number of Java developers, devices running Java, and companies adapting it, it's safe to say that Java will be around for many years to come. This guide will provide everything you need to know about Java programming language before you learn it. More specifically, you will learn about features of Java programming, its applications, reasons to learn it, and how you can learn it the right way. In 1991, the team 'Green Team' led by James Gosling at Sun Microsystems created a programming language for digital consumer devices.
The language was called Oak then. Because there was an oak tree outside Gosling's office. The 'Green Team' demonstrated the use of the language with an interactive television. However, it was too advanced for the digital cable television at the time, and more suitable a technology that was starting to take off, the Internet. Later, the language was renamed Green and finally renamed Java from Java coffee; hence the coffee-cup logo. Since C/C++ was popular back then, James Gosling designed the language with C/C++ style syntax, and philosophy 'write once, run anywhere'.
After years, Sun Microsystems released the first public implementation of Java in 1995. It was announced that the Netscape Navigator Internet browser would incorporate Java technology. In 2010, Sun Microsystems was completely acquired by Oracle Corporation along with Java. Java Version History • June 1991 - Java language project was initiated • JDK 1.0 - January, 1996 • JDK 1.1 - February, 1997 • J2SE 1.2 - December, 1998 • J2SE 1.3 - May, 2000 • J2SE 1.4 - February, 2002 • J2SE 5.0 - September, 2004 • Java SE 6 - December, 2006 • Java SE 7 - July, 2011 • Java SE 8 (latest version) - March 18, 2014 • Java SE 9 - July, 2017 (announced release date) Features of Java Programming Language. • Java is platform independent Java was built with the philosophy of 'write once, run anywhere' (WORA). The Java code (pure Java code and libraries) you write on one platform (operating system) will run on other platforms with no modification.
To run Java, an abstract machine called Java Virtual Machine (JVM) is used. The JVM executes the Java bytecode.
Then, the CPU executes the JVM. Since all JVMs works exactly the same, the same code works on other operating systems as well, making Java platform-independent. • An object-oriented Language There are different styles of programming. Neoragex 5.4 completo. Object-oriented approach is one of the popular programming styles. In object-oriented programming, a complex problem is divided into smaller sets by creating objects.
This makes your code reusable, has design benefits, and makes code easier to maintain. Many programming languages including Java, Python, and C++ has object-oriented features. If you are serious about programming, you should definitely learn object-oriented style of programming. • Java is fast The earlier versions of Java were criticized for being slow. However, things are completely different now. The new JVMs are significantly faster. And, the CPU that executes JVM are also getting more and more powerful.
Now, Java is one of the fastest programming languages. Well optimized Java code is nearly as fast as lower level languages like C/C++, and much faster than Python, PHP etc. • Java is secure The Java platform provides various features for security of Java applications. Some of the high-level features that Java handles are: - provides secure platform for developing and running applications - automatic memory management, reduces memory corruption and vulnerabilities - provides secure communication by protecting the integrity and privacy of data transmitted • Large Standard Library One of the reasons why Java is widely used is because of the availability of huge standard library.
