About Java

Introduced in the 1990s by James Gosling, Java is an object-oriented, robust, and secure programming language. The team started this Java project to develop a language suitable, especially for digital devices like set-top boxes, television, etc. At first, C++ was to be used in the Java project but was not considered for some reasons. Later, Gosling expanded C++ and led to another stage of a project Green, which was later renamed the ‘Greentalk’ project by Gosling and his team members. These project files had the file extension as .gt, which is later recognized as ‘OAK.’

The name ‘OAK’ was given to the project after an oak tree that was located outside Gosling’s office. But later on, the term ‘OAK’ was changed to Java. After various talks and brainstorming sessions, Gosling and his team come to multiple names- JAVA, DNA, SILK, BURY, etc. Still, they decided on JAVA after many discussions due to its uniqueness. This name (Java) comes up from a type of espresso bean. Gosling and his team members had come up with this name while having a cup of coffee near their office.

The main principles on which Java was built are- robust, portable, platform-independent, multi-thread, etc. In 1995, Java was recognized as one of the ten best products in Time magazine. Today, Java has been used in various fields like internet programming, mobile devices, games, etc. later, multiple versions of Java have been introduced over the years with new added features and functionalities.

Multiple copies of Java can be installed on a single computer, and, if you have more than one browser, every one of them could be using a different version or none at all. You can determine your Java version by verifying it on the Java website, or you could check using the Windows command prompt, Mac terminal, or Linux terminal.

Verifying Online

Open a new window in your web navigate to Java’s website. Oracle, the makers of Java, have provided an easy page that will check your Java installation and report the exact version you’re running. This can be done from any operating system.

After a few seconds, check the results! This will include the Version number as well as the Update number. The version number is most important if you’re checking for compatibility with other programs.

Windows

Wait for a black window with white text to appear on your screen. This is called a «console window.»

You can tell what version of Java you have by looking at the number after the «1.» in the first line of the console output. In this example, the user has Java 8 installed.

Mac OSX

With Utilities open, open the Terminal and type in «java -version», then retrieve the current java version.

Linux

• This should return something like Java(TM) 2 Runtime Environment, Standard Edition (build 1.6) If it returns
  -bash: java: command not found
  This means that either it is not installed or you haven’t set up your paths properly

• With Firefox 3 go to Tools Add-ons button and go to the Plug-ins tab.
• With Firefox 2 or 3: In Firefox versions 2 and 3, enter in the address bar: about:plugins. If Java is installed there will be multiple Java entries.
• With Internet Explorer 7 or 8 go to Tools select Internet Options in the General tab click on the Browsing History Settings button and select the View Objects button right click on an ActiveX control and get its properties. Each ActiveX control has a «code base» and for each of the Java entries it will display the version number.
