Oak was unsuccessful, so in 1995 Sun changed the name to Java and adjusted the language to exploit the expanding World Wide Web.

Later, in 2009, Oracle Corporation obtained Sun Microsystems and took responsibility for key Sun programming resources: Java and Solaris.

In 2014 a standout amongst the most critical changes to the Java language was dispatched with Java SE 8. Changes incorporated extra useful programming highlights, parallel processing utilizing streams and enhanced integration with JavaScript. The twentieth commemoration of business Java was praised in 2015.

This language has various components that make the language appropriate for use on the World Wide Web. Little Java applications are called Java applets and can be downloaded from a Web server and keep running on your PC by a Java-compatible browser. Applications and websites utilizing Java won’t work unless Java is introduced on your gadget. When you download Java, the product contains the Java Runtime Environment (JRE) which is expected to keep running in a Web browser. A part of the JRE, the Java Plug-in programming permits Java applets to keep running inside different browsers.

The official Java site gives connections to uninhibitedly download the most recent adaptation of Java. You can utilize the Java website to take in more about downloading Java, verify Java is introduced on your PC, expel more established versions, troubleshoot Java or report an issue.
