tweet.getWords() does not work

System.out.println("The words are: " tweet.getWords());
    for (String word: tweet.getWords())
    {
     System.out.println(word); 
    }

How come when i do tweet.getWords()); it does not work but when i do it on the for command it works. I am confused.

[MOD: added ```java formatting -cf]

Remove 'tweet.getWords()' located after "The words are: ".

This should cause a compiling error due to the incorrect Java syntax.

The reason is that System.out.println expects a String. To provide a String in your example you'd have to concatenate the String "The words are:" with the output of tweet.getWords() by using the + sign.

System.out.println("The words are: " + tweet.getWords());

Keep in mind that tweet.getWords() returns a String array. Arrays default toString() method usually don't return a nice String for their elements. Here you could use your System.out.println method for example to print every String within your for loop (taking one String out of the array once).

Hope this helps,
