Don't use nextLine, it interacts weirdly with all the other nextX() methods. Instead, change the scanner's delimiter. After making a scanner, invoke:

scanner.useDelimiter("\r?\n");

Then to get e.g. an int, call .nextInt(). And to get somebody's name, call .next() (and don't call .nextLine() for anything).
