The compiler is not able to determine that 'myComputerName' will exist
because you only instantiate it inside of an IF statement
you should do a:
String myComputerName = new String();
outside of your IF so that the object is brought into scope, then
just perform a value assignment inside the IF
myComputerName = myComputer.getComputerName();
That way there will always be a 'myComputerName' object to satisfy the
compiler.
