Which came first, Instagram or Java?

Java came first, by 15 years. Sun Microsystems announced Java publicly.

Side by side

Instagram

Instagram launched in October 2010 as an iPhone-only app and took 25,000 users on its first day. Facebook bought it in April 2012 for about $1 billion when it had thirteen employees and no revenue. It is four years younger than Twitter and six years older than TikTok.

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.
