Could someone tell me what's wrong with my code in Java?

I'm mostly having trouble with example 7. It will print the congratulations statement instead of the you will statement. I'm also not sure if any of my recent changes affected my other outputs. But my main objective is for the code to match all of the inputs and outputs. I'm going to add my code to the comments because it makes it too long to ask a question.
