If you want an array of primitive data type, then execute the code given below. 

List<Integer> list = ...;
int[] array = new int[list.size()];
for(int i = 0; i < list.size(); i++) array[i] = list.get(i);

Either:

Foo[] array = list.toArray(new Foo[list.size()]);

or:

Foo[] array = new Foo[list.size()];
list.toArray(array); // fill the array
