4,254 PointsIt 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);
