How to convert a List to an Array in Java

Question

I am working on a List and I want to convert it into an Array. How can I do this?

Answer 1

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);

Answer 2

String[] strings = list.stream().toArray(String[]::new);

Answer 3

Either:

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

or:

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