In 1995, a small team of engineers unveiled a new programming language designed for flexibility, portability, and robustness. That language was Java. And three decades later, it remains one of the most influential technologies in the software world. Thank you for helping us celebrate #30YearsOfJava this past year. We look forward to many, many more years of pushing the boundaries of innovation and the pursuit of developer excellence. ❤️
