there bug in viewcustomerrecords. allow "11" option view customers. 10 (i.e. 11 minus 1) not valid index c[], goes 0 9, checking if record c[10] null before checking else.

for matter, think let type in above 11 well, , cause exception.

rearranging tests fix particular problem:

    if (filenum > 11 || filenum < 1)     {         system.out.println ("that not valid option");         viewcustomerrecords (c);     }     else if (filenum > 0 && filenum < 11)     {         if (c [filenum - 1] == null)         {             system.out.println ("this record empty");             menu ();         }         else         {             system.out.println ("customer # " + filenum + "\n");             c [filenum - 1].print ();             menu ();         }     }     else     {         // . . . show customers . . .

if got arrayindexoutofboundsexception exception when typing in "11" problem reported. otherwise, maybe have 2 problems. :-)
