Today, billions of devices and services run java, everything from computers, electronic systems in cars, IoT devices, gaming consoles, PoS systems, medical devices, and many others, including a wide range of emerging tech.
Officially released in 1995, Java is something of an elder statesman among programming languages. In a field that is constantly innovating, with new technologies routinely supplanting once-popular languages that inevitably fade, Java has maintained its place and relevance as a mainstream language for application software development. Many developers still prefer it over other powerful languages like Python, Ruby, PHP, Swift, C++, and others. That alone speaks volumes about its capabilities.
