The Java programming language and Java software platform have been chastised for design decisions such as generics implementation, forced object-oriented programming, unsigned number handling, floating-point arithmetic implementation, and a history of security vulnerabilities in the primary Java EE platform. These criticisms have led some experts to question whether the platform is suitable for mission-critical applications.
James Gosling created Java as an object-oriented programming language in the early 1990s. Over the years, the language has served as the foundation for millions of programs running on a variety of platforms, including Windows, Macintosh, UNIX, Android-based portable devices, Embedded Systems, and business solutions.
Although originally designed for use in desktop applications, over time it has become clear that Java is also very suitable for embedded systems. With its lightweight architecture and built-in security features, it's easy to deploy Java code in the cloud or on mobile devices without compromising performance or battery life.
In 2004, Sun Microsystems released the first version of the Java Standard Edition (Java SE). This was followed by several release candidates and then by two stable releases per year. In addition, since 2010 there is also a monthly release of a Java Development Kit (JDK) with only bug fixes and improvements.
Sun Microsystems stopped supporting Oracle's proprietary license in 2014 and now licenses Java under a free software license. Since then, there have been multiple independent implementations of the language, including from IBM, IntelliJ IDEA, and SAP.
The most recent version of Java is 8, which was released in October 2016. It is expected that 9 will be released in April 2017. Version 10 is scheduled for release in December 2018. However, given the evolution of the platform and development tools, this estimate may change.
Java is also known for its steep learning curve and verbose syntax. Some believe this to be one of the main reasons why it has never become as popular as Perl or PHP among new programmers.
Finally, Java is seen as a proprietary language due to its licensing scheme which requires that all software produced using Java undergo a license check before being distributed. The OpenJDK project provides its source code under an open source license, but many companies use their own license when selling Java-based products.
Despite these criticisms, there are several advantages to using Java over other programming languages. One advantage is its wide support: since its introduction in 1995, Java has won over the hearts of developers all over the world by supporting various platforms (from mobile phones to supercomputers) and operating systems (from web browsers to cloud servers).
Another advantage is its availability: since its creation, hundreds of thousands of people around the globe have earned a living by creating high-quality apps for smartphones, tablets, and other gadgets.
Sun MicroSystems officially defines Java as having the following features:
The fact that Java is an object-oriented programming (OOP) language at its heart makes it one of the most popular languages. OOP provides a clean modular framework that makes it easier to tackle difficult issues. Now, let's have a look at some of Java's greatest characteristics that make it so popular!
First, Java is open source. This means that the language's development is driven by its community of users and developers who can contribute ideas and code. This active community is what has made Java such a success story after almost 20 years on the market.
Second, Java is cross platform. This means that it can run on many different platforms and operating systems without any problems. This is because Java uses standard interfaces to communicate with the hardware and it's easy for software to be ported between different operating systems and architectures.
Third, Java is fast. It's very efficient and doesn't require much memory to run. This is due to the fact that it implements much of its own functionality and it uses static typing instead of dynamic typing. These features make Java perfect for creating applications that process large amounts of data in quick time.
Fourth, Java is secure. Specially when used in an environment with a strong access control mechanism, such as a controlled network, Java is very safe. This is because it has built-in mechanisms that prevent unauthorized individuals or programs from executing code in your computer.
Java was designed to be easy to use and is therefore easier to write, compile, debug, and learn than other programming languages. Java is object-oriented. This allows you to create modular programs and reusable code. Java is platform-independent. This means that it can run on any computer with a Java installation.
The disadvantages of Java programming are its relative complexity and the fact that it is not free software like many other programming languages. It is also difficult to program in Java for people who are not used to working with objects and classes. However, these issues have been overcome by using tools such as static analysis systems which detect errors in your code early and help avoid bugs during development.
Java has been widely used in web applications because of its efficient technology and its ability to be deployed on numerous types of computers. This makes it suitable for large-scale projects that require reliability and security.
