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.

I think you have to loop. However, auto-unboxing will allow you to use Integer objects in many places where an int is required.
