Convert List of Integer Objects to primitive int array!!

Question

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<Integer> 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.
