The computer that Java code targets is the Java Virtual Machine (JVM).

Stranger still, this computer doesn't actually exist. In a way, Java isn't compatible with anything but one computer. Java's approach to achieving this feat is counterintuitive at first. It's the realization of cross-platform code that works the same across any system you run it on. Java is the solution to this incongruity. It feels arcane in the world of advanced computers that we can't just write code and send it to anyone who wants to run it without worrying about what platform they're on. Code has to be compiled from a human-friendly programming language into machine language, a series of binary instructions derived from what a CPU is designed to respond to.

It seems a pity that such a thing still happens on computers so advanced that they can run virtualized computers within computers, keep old video games alive through emulation, and even fit in your pocket, but software delivery is actually pretty difficult. It's why there are so many download buttons on any given software site: a button for Windows, for macOS, for Linux, for mobiles, and sometimes even more.Īs a user, a typical scenario is you want to download some great software but find it's not available for your platform. This is compounded when you try the software on another operating system (OS). It should work, but as any programmer knows, something always gets overlooked. As a developer, your troubles are likely to begin when you send software that works perfectly on your own computer to some other computer it probably won't work. The best way to understand what Java solves is to develop software, but just using software is a good start, too.

Then you can understand why and how it benefits developers and users. To understand what makes Java important, you have to understand the problem it claims to solve. It was proprietary at first, but in 2007, Java was released as open source under the GPL. Java was released in 1995, making it 26 years old as I'm writing this.
