History of Java
Java has a rich history that dates back to 1991 when it was first developed by James Gosling and his team at Sun Microsystems.
The language was initially called Oak and was designed for use in embedded systems, but it later evolved into a full-fledged programming language.
In 1995, Java was released as a programming language and platform, and it quickly gained popularity due to its platform-independent nature and ease of use.
Over the years, Java has continued to evolve, with new versions and features being added regularly, including the introduction of Java SE 17, which is covered in many introduction to java programming pdf resources.
Today, Java is one of the most widely used programming languages in the world, with a large community of developers and a wide range of applications.
