alphabetizing a list from a single string

I'm trying to create a program that takes in a single string and sorts the words by alphabetical order, this is what i have at the moment but nothing is printing out:

System.out.println("Enter words, sepaated by commas and spaces");
      String input= scanner.next();
      String[] words= input.split(" ");
      Arrays.sort(words);
      StringBuilder zoop= new StringBuilder();
      for(int i=1; i<words.length; i++){
       zoop.append(" ");
       zoop.append(words[i]);
      }
      String sorted= zoop.toString();
      System.out.println(sorted);

Scanner scanner = new Scanner(System.in);
String input = scanner.nextLine();

and 

for(int i=0; i<words.length; i++){

scanner.next() only returns the next complete token. In your case, it returns just the first word. Since the for loop started with 1 instead of 0, the program printed nothing.

You have two errors that cooperate to produce no output. First, look at the difference between Scanner.next() and Scanner.nextLine(). Then realize that arrays are 0-based in Java and take a second look at your for loop.

for(int i=1; i<words.length; i++){

should be

for(int i=0; i<words.length; i++){
