Answer Posted / imtiyaz
if you want to call a methods which are specific to the
platform or if you want to use the OS calls or if you want
to use functionality which is developed in other language
we go through native interface.
In a real world we need to execute statements which are
specific to platform which java may or may not do, and
other language can do much faster than java at that time we
use to write the methods in that language and use that code.
And sometimes the code already developed in other language
and it is very cost effective or time consuming to convert
the code into java at that moments also we use java native
interface.
