    Default Re: i cannot figure out what's wrong

    A pitfall of using nextInt and nextDouble is that those methods do not consume the end of line. When user enters the salary of employee 1 the EOL is still in the buffer. When the program reaches the line asking for the name of employee 2 it scans the EOL still in the buffer and returns an empty String. Simple solution: add a call to nextLine after the call to nextDouble.
