Convert List of Integer Objects to primitive int array!!

Stephen Hawking

Hi Experts,
I have started learning java recently and looking into some practice exercise. Just wante to know if there is a easy way, to convert a List of java.lang.Integer objects to array of primitive int type (not integer).
Something like List to int []? Or I need to loop through each element in list and convert it?
Please let me know.
Please feel free to move this thread to right location just in case I have posted this in the wrong place. Thanks in advance.

I don't think there is an easier way to do it.

Whilst you could use the List.toArray method to produce an Integer[], you can't then convert Integer[] to int[] without using a loop!

So, I'd stick to the way you're currently doing it.
