Hi,

Suppose you have a collection with the name myCol then you can use the following code:

 String[] myArray = myCol.toArray(new String[0]);

Above is using Java 7. But you can also do like this in Java 8:

String[] result = myCol.stream()
    .map(x -> new String(x))
    .toArray(size -> new String[size]);

Above code is using the stream in Java 8.

Thanks
