Indonesian island’s programming language (4)
I believe the answer is:
java
I believe this is a triple definition!
'indonesian' is the first definition.
(Java is an island of Indonesia)
'island's' is the second definition.
(Java is an example)
'programming language' is the third definition.
(I've seen this in another clue)
(Other definitions for java that I've seen before include "Coffee (slang)" , "Indonesian island known for coffee" , "Most populous Indonesian island" , "Large island; coffee type" , "Its capital is Jakarta" .)
