Example.java 
// I have initialized a java.io.Console for you. It is in a variable named console.

Try to think it through what you are doing:

In your "response" variable, you are saving the userinput. Currently, you prompt the user just once.

Then, in your loop, you have "noun" that is currently nothing, and eventually not even needed. You end your loop again on nothing, because "inInvalidWord" is never initialized.

Here is some pseudocode:

Make a String variable named prompt;
do{
   get the input from the user and save it in your promptvariable;
}while(loop as long as the user gives the right input );
