Java Introduction: What Is Java, Who Created It, and How Sun Microsystems Became Oracle?

Java is a high-level, general-purpose programming language designed to be portable across different platforms. Its core concept, "Write Once, Run Anywhere," allows Java programs to run on various operating systems, provided a compatible Java Virtual Machine (JVM) is available. This portability became one of Java's most significant features.

Java was primarily developed by James Gosling and a team of engineers at Sun Microsystems during the early 1990s. Originally called Oak, the language was designed for consumer electronic devices. However, it was later redirected towards the Internet and renamed Java.

Sun Microsystems was an American technology company that developed and sold computer hardware, software, and related technologies. They were known for technologies like Java, Solaris, SPARC processors, computer servers, workstations, storage, and networking technologies. Sun's Network is the Computer idea emphasized the importance of networking in computing.

Sun's Green Project aimed to create software for emerging consumer electronic devices, focusing on portability due to the diversity of hardware across devices. This led to the creation of the Oak language, which later became Java after shifting towards Internet applications.

Java was publicly introduced in 1995, just as the Internet was gaining popularity. Its portability and network capabilities made it an attractive choice for network-oriented applications. The Java compiler converts source code into bytecode, which is then executed by the JVM, allowing the same bytecode to run on different operating systems.

In April 2009, Oracle acquired Sun Microsystems, acquiring Java along with other important technologies. Oracle now stewards Java, ensuring its continued development and maintenance.
