  • Duke is its Official Name for the Logo

    Duke is a cute, arm-and-leg coffee cup figure that serves as Java’s official mascot. Since its introduction in 1996, Duke has come to represent Java. It is present at Java conferences, events, and on a range of products related to Java.

  • May 23, 1995, is its Birthday

    Java, like all other innovations, has a birthday! Java 1.0 was officially released on May 23, 1995. Although there have been many upgrades and advancements to the language since then, this day is still a significant turning point in the development of Java. 

  • WORA is its Principle

    The fact that Java is platform-neutral is one of its greatest advantages. The “Write Once, Run Anywhere” (WORA) idea is to blame for this. Writing Java code results in its compilation into bytecode, which is compatible with any Java Virtual Machine (JVM) and can operate on any host operating system. Because of this, Java has emerged as the preferred language for creating cross-platform apps. Again, we have a question for you. You choose Java or Python: Which is the preferred programming language for you?

  • Oak is its Original Name

    Coffee is the unexpected source of Java’s name! Java was named while James Gosling was enjoying a cup of coffee. Gosling’s love of coffee served as inspiration for the creation of the beverage. The language was originally called “Oak,” but Java was later added to it to reflect the rich culture around coffee in Indonesia, home to the world’s best coffee farms. 

    Given that the magic number “0xCafeBabe” in the class files was titled after the cafe where the Java crew frequented to get coffee, there appears to be some truth. Explore the top 10 reasons why you should study Java.

  • Finally Java

    Team put multiple names like DNA, Silk, Ruby and Java. Java was finalized by the team. James Gosling tabled Java title based on type of espresso coffee bean. Java is an island in Indonesia where new coffee was discovered termed as Java coffee. As per James Gosling, Java was among the top choice along with Silk. Finally Java was selected as it was quite unique and represented the essence of being dynamic,revolutionary and fun to say.

    Sun released the first public implementation as Java 1.0 in 1995. It promised Write Once, Run Anywhere (WORA), providing no-cost run-times on popular platforms.

    On 13 November, 2006, Sun released much of Java as free and open source software under the terms of the GNU General Public License (GPL).

    On 8 May, 2007, Sun finished the process, making all of Java’s core code free and open-source, aside from a small portion of code to which Sun did not hold the copyright.

    The latest release of the Java Standard Edition is Java SE 21. With the advancement of Java and its widespread popularity, multiple configurations were built to suit various types of platforms. For example: J2EE for Enterprise Applications, J2ME for Mobile Applications.

  • Oak

    James Gosling renamed language to Oak. There was an Oak tree in front of his office. James Gosling used this name as Oak represents solidarity and Oak tree is the national tree of multiple countries like USA, France, Romania etc. But Oak technologies already had Oak as a trademark and James team had to brainstrom another title for the language.

  • Java Name History

    GreenTalk

    James Gosling was leading a team named as ‘Green’ team. Target of this team was to create a new project which can. Initially C++ was the original choice to develop the project. James Gosling wanted to enhance C++ to achieve the target but due to high memory usage, that idea was rejected and team started with a new language initially named as GreenTalk. The file extension used as .gt. Later this language was termed as Oak and finally to Java.

  • History of Java

    Java programming language was originally developed by Sun Microsystems which was initiated by James Gosling and released in 1995 as core component of Sun Microsystems’ Java platform (Java 1.0 [J2SE]). History of even naming of the Java is very interesting. It went under many names.

  • Garbage collection

    Java provides automatic garbage collection that cannot be controlled by the programmer. It doesn’t provide the methods like delete() and free() to free the memory.

    However, due to the various disadvantages, Java is one of the most used programming languages due to its advantages, making it platform-independent, secure and a robust programming language.
