Tempting fruit basket's last one made in Java (6)
I believe the answer is:
applet
'one made in java' is the definition.
(Java is a programming language)
'tempting fruit basket's last' is the wordplay.
'tempting fruit' becomes 'apple' (fruit in many depictions of the Garden of Eden).
'last' indicates one should take the final letters.
The final letter of 'basket' is 't'.
'apple'+'t'='APPLET'
(Other definitions for applet that I've seen before include "modest programme" , "limited application of computing" , "Computer application, sounds like small fruit" , "Java program" .)
