How can I convert a Jsoup Document[] array to a String[]?

Question

My question is the same as this one except that instead of a single Document I have an array (Document[]).

I normally use R, not Java, so I apologize if it should be apparent how to change the solution from the linked thread for the case of an array.

The solution for the case of a single Document object was:

String htmlString = doc.html();

My code to create the object was:

Document[] target = new Document[20];
for(int n=0; n < strvec.length;n++){
    target[n] = Jsoup.connect(strvec[n]).get();
 }

I tried a few things like creating the original target object as String[], putting .toString() on the end of Jsoup.connect(strvec[n]).get() and elsewhere, but these attempts were unsucessful.

it is assumed that serves is an array of String containing the URL to connect, you do not need to create another array of Document

String[] result = new String[strvec.length];
    for(int n=0; n < strvec.length;n++)
      result[n]=Jsoup.connect(strvec[n]).get().html();

String[] htmlList = new String[target.length];
for(int i = 0; i < target.length; i++)
    htmlList[i] = target[i].html();

This loop should do what you want.

Thank you. It didn't give an error in the IDE when I pasted that in, but when I tried to run it it threw this error on the last line of that codeblock `Exception in thread "main" java.lang.NullPointerException` – Hack-R Sep 12 '16 at 01:15
