Hi people,
sorry i have a question which might be stupid but i want to clarify something. For my DB interface i have the following statement:
// Returns an array of record numbers that match the specified
// criteria. Field n in the database file is described by
// criteria[n]. A null value in criteria[n] matches any field
// value. A non-null value in criteria[n] matches any field
// value that begins with criteria[n]. (For example, "Fred"
// matches "Fred" or "Freddy".)
public int[] find(
String[] criteria);
does a null value in can be null or "" or it only refers to null?
