GTA V: Java Update Coffeeshop - Orcz.com, The Video Games Wiki

java.update() is a coffeeshop in Los Santos

It is a reference to Java (the coffee bean) and Java (Programming language)

Their signage combines both in a clever way, for example:

 public int bread;
 public int bacon;
 public void sandwich () {
 bread = 2;
 bacon = 2;
 return bread + bacon;
 }

You can find this shop on Boulevard Del Perro
