Answer 1

Do it the old Java 6 way and add the comma yourself unless its the last element in the list.

See the following example:

private String[] mostlyMatchedKeywordsStrings = serialResponse.getData().getGenres();
private List cloudChipList = new ArrayList<>();

for (int i = 0; i < mostlyMatchedKeywordsStrings.length; i++) {

    String str = mostlyMatchedKeywordsStrings[i];

    if (i + 1 < mostlyMatchedKeywordsStrings.length) str = str + ", ";

    cloudChipList.add(str);

    if (cloudChipList.size() > 0) {
       infoSerialFrag_GenreChips.addChip(str);
    }
}
