Is there a way to convert a List of Integers to an Array of int (not Integer)? Something like List to int []? Without looping through the list and manually converting the integer to int.

I’m sure you can find something in a third-party library, but I don’t believe there’s anything built into the Java standard libraries.
I suggest you just write a utility function to do it, unless you need lots of similar functionality (in which case it would be worth finding the relevant 3rd party library). Note that you’ll need to work out what to do with a null reference in the list, which clearly can’t be represented accurately in the int array.
