How to convert Integer[] to int[] array in Java?

Question

Is there a fancy way to cast an Integer array to an int array? (I don\'t want to iterate over each element; I\'m looking for an elegant and quick way to write it)

Answer 1

Using Guava, you can do the following:

int[] intArray = Ints.toArray(intList);

If you're using Maven, add this dependency:

   com.google.guava
   guava
