What is JAVA?

Java is a programming language developed by Sun Micro-systems that is used to develop programs that run on Windows, Mac, and Linux computers or can be integrated into sites. It was originally designed to develop programs for decoders and portable devices, but then it became a popular choice for creating web applications. Java allows you to play games online, talk to people around the world, calculate your mortgage interest and see 3D images, just to name a few.” It is also an integral part of intranet applications and other solutions of e-business that are the basis of corporate computing. ”

Java is a general-purpose computer programming language that is simultaneous, class-based, object-oriented,and specifically designed to have as few implementation dependencies as possible. The goal is to allow application developers to “Write once, Run anywhere” (WORA),  meaning that compiled Java code can be executed on all platforms that support Java without the need for recompilation. Java applications are usually compiled for the bytecode that can be run on any Java virtual machine (JVM), regardless of the architecture of the computer. As of now, Java is one of the most popular programming languages in use, particularly for client-server web applications, with 9 million developers reported. Java was originally developed by James Gosling at Sun Microsystems (which has since been acquired by Oracle Corporation) and launched in 1995 as a core component of the Sun Microsystems Java platform. The language derives much from its C and C ++ syntax, but has less low-level facilities than any of them.

Java compilers, virtual machines, and reference and original implementation class libraries were originally released by Sun under proprietary licenses. In May 2007, according to the specifications of the Java Community Process, Sun relates most of its Java technologies under the GNU General Public License. Others also developed alternative implementations of these Sun technologies, such as the GNU compiler for Java (compiler bytecode), the GNU Classpath (standard libraries) and the Iced Tea-Web (browser plugin for applets).

The most recent version is Java 11, released on September 25, 2018, which follows Java 10 after just six months ,according to the new release schedule. Java 8 is still compatible, but there will be no more security updates for Java 9. Versions prior to Java 8 are supported by companies on a commercial basis.

Java syntax is similar to C ++, but it is strictly an object-oriented programming language. For example, most Java programs contain classes, which are used to define objects and methods, which are assigned to individual classes. Java is also known to be more rigid than C ++, which means that variables and functions must be defined explicitly. This means that the Java source code can produce errors or “exceptions” more easily than other languages, but it also limits other types of errors that can be caused by undefined variables or by unassigned types.I suggest you install only Java on the official site. When installing Java, configure to update automatically. As Java runs on PC and Mac, hackers can write programs in Java that can infect almost all computers that surf the Internet today. Keeping Java updated and corrected is essential for computer security and to develop Web applications.
