I am trying to write a program and the user inputs how many dice and rolls they want. The output is a histogram using dashes. I'm not sure what is wrong with my code at this point.

Please properly format your post. Use highlight tags around your code. And please don't type in all caps. That usually has the connotation of shouting.

What is wrong? Are you getting an exception? If so, please post the error message. Otherwise, please post an example input and the output you're getting, along with a statement of what the correct output should be.

It works when I run and compile it except the - are after the number. Also you should have an import statement at the top declaring your importing the scanner class.
