[Bluej-discuss] Ex 4.50

[Davin McCall]

The error messages produced by the compiler are a bit cryptic, but they are meaningful. In this case you will find the error message actually says something more like "size has private access in java.util.List". The reason is that your code accesses the (private) field member called "size" as if it were a field, when in fact what you need to do is call the (public) method member, "size()".

Using brackets "()" indicates that you are making a method call. Replace "notes.size" with "notes.size()" and this particular error should go away.

You may also need to change "int index;" into a proper initializer, eg "int index = 0;" before this code will compile.
