What is Java
Java is a programming language that developers use to create applications on your computer devices. Sun Microsystems released the first public implementation as Java 1.0 in 1995. It promised "Write Once, Run Anywhere" , providing no-cost run-times on popular platforms. It can be used to create complete applications that may run on a single computer or be distributed among servers and clients in a network.
Oracle Corporation is the current owner of the official implementation of the Java SE platform, following their acquisition of Sun Microsystems on January 27, 2010. According to Oracle, as of 2016, Java is one of the most popular programming languages in use, particularly for client-server web applications, with a reported 9 million developers.
