A primitive cannot be "dereferenced" like an object. This is a static method of the Character class (so you call it using the class name rather than an instance), taking a char as the argument...

Character.isLetterOrDigit(c)

There's probably a better way, but I believe this would work...

if(Character.isLetterOrDigit(c) || c=='\n' || c=='\r')
