     */
    public static void main(String[] args) {
        String str="Quick brown fox jumps over the lazy dog";
        String arr[]=str.split(" "); // split the sentence in an array of words
        System.out.println("Words List:");
        for ( int i = 0 ; i < arr.length ; i++ ) {
            System.out.println(arr[i]);
        }
        System.out.println("");
        System.out.print("Words Count: ");
        System.out.println(""+arr.length); // displays the counts
    }
    }
