The toArray() method of the Ints class returns an array containing each value of collection, converted to a int value in the manner of Number.intValue(). Following is the syntax −

Here, the parameter is the collection of Number instances

Example
import java.util.Arrays; import java.util.List; import com.google.common.primitives.Ints; class Demo { public static void main(String[] args) { List<Integer> list = Arrays.asList(20, 40, 60, 80, 100, 120, 140, 160); System.out.println("List = "+list); int[] myArr = Ints.toArray(list); System.out.println("Array (from list) = " + Arrays.toString(myArr)); } }
Output
List = [20, 40, 60, 80, 100, 120, 140, 160] Array = [20, 40, 60, 80, 100, 120, 140, 160]
