Indonesian island or a programming language (4)
I believe the answer is:
java
This clue is a double definition.
'indonesian island' is the first definition.
(I've seen this in another clue)
'a programming language' is the second definition.
(I've seen this in another clue)
(Other definitions for java that I've seen before include "Jakarta's island" , "Indonesian island known for coffee" , "Large island; coffee type" , "Catlike" , "Indonesian island - computer programming language" .)
