Java was created in the early 90s by Green Team under leadership of James Gosling from the Sun Microsystems company. Java was invented by accident. Gosling and his team were developing a TV console. They started the development with the C++ “refining”, and they got a new language as a result.
Initially, they called the language “Oak” after the oak tree which grew near the Sun office. But very soon they found out that this title had been already registered for some computing company. That’s why they renamed the language to “Green” and then to “Java”. The language got its final name after the coffee trademark. That’s the reason why you can see the teacup on the language logo.
Java is constantly being improved. One of the most important strong points of the language is compatibility between an old and new code versions. Today, Java applications are functioning on any device or OS: computer, smartphone, or even a Tesla car. A great number of companies of any scale use this universal language. The language is widespread, and it allows Java developers to easily find an interesting job and to opt for some other business if they wish.
