It looks as if you're almost there. Your problem lies with this line within your loop:

System.out.println("numberWords");

Essentially, every time the loop runs, you're just printing the string "numberWords" to the console. Instead, you should be printing the variable numberWord. Your line should look like this:

System.out.println(numberWord);
