To get you started, I will show you a simple example:

String str = "\nArticle\n\nArticle\nArticle";

// Split the String by \n
String[] words = str.split("\n");

// Keep the count of words
int wordCount = 0;

for(String word : words){
   // Only count non-empty Strings
   if(!word.isEmpty()) {
       wordCount++;
   }
}

// Check, answer is 3
System.out.println(wordCount);
