Write once, run anywhere

"Write once, run anywhere" (WORA) is a slogan created by Sun Microsystems to illustrate the cross-platform benefits of the Java language. Ideally, this means Java can be developed on any device, compiled into a standard bytecode and be expected to run on any device equipped with a JVM. The installation of a JVM or Java interpreter on chips, devices or software packages has become an industry standard practice.

For example, this means a programmer can develop code on a PC and can expect it to run on Java enabled cell phones, as well as on routers and mainframess equipped with Java, without any adjustments. Hence the expression 'Write once, run anywhere.' This is intended to save software developers the effort of writing a different version of their software for each platform or operating system they intend to deploy on.
