Cannot Find Symbol
<p>I tried compiling my personal contacts database program, but I have nothing
but "cannot find symbol" errors
Should I be instantiating an object more often than once?  If not, what is wrong with this code?</p>

<p>I moved writetoFile and readFile initializations to outside try block, and declared them inside, and it helped! Now the only compiler error messages are the ones shown at the very bottom. </p>
