Collect Objects in Array

Question

I want to filter the CC addresses of the array and want to collect it to the same array,

FOR EXAMPLE

String[] ccAddress = emails.split(";");
ccAddress = Arrays.stream(ccAddress)
                  .filter(adr -> "".equals(adr) == false)
                  .collect(Collectors.toArray);// ?????

My question is, 'Is there any direct way to collect filtered elements to the array in Java8' ?

NOTE : I know I can simply collect them to List and write list.toArray() to get array but that is not my question.

Answer 1

Did you checked documentation?

You can use Stream.toArray method:

String[] ccAddress = emails.split(";");
ccAddress = Arrays.stream(ccAddress)
        .filter(addr -> !addr.isEmpty())
        .toArray(String[]::new);
