Java machines are found everywhere, from computers to tablets to cellphones. Jupiterimages/Photos.com/Getty Images. Released in 1995, the philosophy behind Java is write once, run anywhere.. In other words, a program written in Java can theoretically run on any machine that supports it.While the implementation adds a few caveats to that claim, Java is a powerful and flexible language that can run on many platforms.ndividual computers often use different machine languages, so if you compiled a Java program to a single machine language, the compiled program would not be able to run on multiple machines. To solve this problem, the Java Virtual Machine is a simulated machine which has multiple implementations for each computers.
