Put words in a string array

public static String[] wordList(String line){
    Scanner scanner = new Scanner(line);
    String[] words = line.split(" ");
    for( int i=0; i<words.length; i++)
    {
        String word = scanner.next();
        return words[i] = word;
    }
    scanner.close();
}

On the line return words[i] = word; I get the error message saying "cannot convert String to String[]". Help?

Assuming you're trying to split by spaces, you're method should look like:

public static String[] wordList(String line){
    return line.split(" ");
}

line.split() already gives you an array, you just need to return that:

public class Test {
    public static String[] wordList(String line){
        return line.split(" ");
    }

    public static void main(String args[]) {    
        String xyzzy = "paxdiablo has left the building";
        String[] arr = wordList(xyzzy);
        for (String s: arr)
            System.out.println(s);
    }
}

Running that gives:

paxdiablo
has
left
the
building

Keep in mind that's for one space between each word. If you want a more general solution that uses a separator of "any amount of whitespace", you can use this instead:

public static String[] wordList(String line){
    return line.split("\\s+");
}

The regular expressions that you can use with String.split() can be found here.

String[] words = line.split(" ");

Is all you need. The split() method already returns an array of Strings.
