When the technology was founded: 1995. Not quite 20 years old, though.
Why the technology will be around for another 20 years: Java is integral to so many devices and applications, on hardware and software systems alike. From Blu-ray players to mobile devices, cars and desktop operating systems and cloud-based applications, Java is absolutely everywhere.
And for that reason alone, it is all but indispensable to our every day working and leisure time, and is why Java will - not might - last another 20 years at very least.
