Which came first, the iPhone or Java?

Java came first, by 12 years. Sun Microsystems announced Java publicly.

Side by side

the iPhone

Announced on 9 January 2007 and on sale from 29 June, the first iPhone had no app store, no copy and paste, no 3G and no video recording. The App Store arrived over a year later in July 2008. Android Inc. had been founded in 2003, four years before the iPhone, but the first Android phone shipped fifteen months after it.

Java

Java was announced in May 1995, having started in 1991 as a project called Oak aimed at interactive television — a market that did not exist yet. Its promise was "write once, run anywhere", achieved by compiling to bytecode for a virtual machine rather than to a specific processor. JavaScript arrived seven months later and was named after it purely as a marketing decision; the two languages are unrelated.
