Java 8 has added the Stream API that helps to easily perform bulk operations on Collections. A new method called stream() has been added to all the collection interfaces that returns a Stream corresponding to the underlying collection.
There is a toArray method available on the Stream interface that can be used to convert the Stream to an array. So this method can be used to convert a List to an array. There are two overloaded versions of this method as explained below.
This Stream.toArray method does not accept any input parameter and it returns an object array. The following code demonstrates this approach:
Here, firstly the stream() method is invoked on the input List. This returns a Stream corresponding to the List. Then the toArray method is invoked on the Stream. This returns an object array.
Hence this code prints the following output:
2 4 6 8 10
