Look at line 27 and find the variable that has a null value. Then backtrack in the code to find out why that variable does not have a valid value.

would that be for the line = keyboard.nextLine(); ??

Can you look in your editor and count the lines?
Or add a println that prints out the value of all the variables on the line and see if any of them are null.
