How to remove white spaces between paragraph in Jsoup output paragraphs?

Here is my code. When output printing that print white space between paragraphs also. How can I remove white spaces between paragraphs and then I want to store sentence by sentence in array list.

    public static void main(String[] args) {

    try {
          String url = "http://www.divaina.com/";

          System.setProperty("http.proxyHost", "cache.mrt.ac.lk");
          System.setProperty("http.proxyPort", "3128");

          Document doc = Jsoup.connect(url).timeout(10000).get();

          Elements paragraphs = doc.select("p");
          for(Element p : paragraphs){
            System.out.println(p.text());}
                } 
        catch (IOException ex) {
            ex.printStackTrace();
           }


}

When I'm directly adding content into database white spaces also adding it. How can I remove those white spaces between paragraphs? Actually I want to read content of web page and line by line adding to the database. Is there any other proper way to do it?

Obviously some of paragraphs contain no text. This might help: 

for (Element p : paragraphs) 
{
    if (p.text().length() != 0)
    System.out.println(p.text());
}

Use regular expression:

String withoutspace = whitespace.replaceAll("\\s", "");

Or try this

String withoutSpace = whitespace.replace("\n", "").replace("\r", "");
