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 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. http://www.fromdev.com/

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.
