This week's book giveaway is in the OCMJEA forum. We're giving away four copies of OCM Java EE 6 Enterprise Architect Exam Guide and have Paul Allen & Joseph Bambara on-line! See this thread for details.
On line 6 you declare 4 variables, c, sw, random and n. These all have the same type, int. int is one of the primitive types in Java which means it does not have any methods or fields you can call using the dot operator.
You are calling n.nextInt(47);. There are two methods called nextInt that take a single int value - one in java.util.Random and one in java.util.Scanner. Since in the latter the int is the radix I assume you actually want the former. For that you would need an instance of java.util.Random.
I think that line 6 is actually a mistake; either you copied it incorrectly or your teacher made a mistake. I think it should be this:
And can you please UseCodeTags next time? Make sure to preserve the indentation as well.

There's a whole industry of certification exams which appears (to me) to require people to look at horribly bad code and figure out what it does. On the one hand, figuring out what horribly bad code does is a useful skill. But on the other hand I have this sinking feeling that the people who take those exams might be taking the exam questions as examples to be imitated.
