How to use ResultSet on enumeration objects
0
I wanted use getInt, getString on DueDate, LoanDuration, and Status. But not working. They have set methods that use Class type parameter.
dueDate, loanDuration, status use enumeration.
My code:
private static Copy getCopyFromResultSet(ResultSet rs) throws SQLException {
Copy copy = null;
if (rs.next()) {
copy = new Copy();
copy.setID(rs.getInt("ID"));
copy.setDueDate(rs.getInt("DueDate")); // getInt doesnt work
copy.setLoanDuration(rs.getString("LoanDuration")); //getString doesnt work
copy.setStatus(rs.getString("Status")); //getString doesnt work
}
return copy;
}
// my set methods for loanDuration, DueDate, status.
public void setDueDate(LocalDateTime dueDate) {
this.dueDate.set(dueDate);
}
public void setStatus(Status status) {
this.status.setValue(status);
}
public void setDueDate(LocalDateTime dueDate) {
this.dueDate.set(dueDate);
}

LocalDateTimeis not anEnum. Edit your Question to explain exactly what you mean by: “are enumeration classes.”. Until then I am voting to close as unclear. For date-time values, use date-time types in your database and in Java, with no need for an enum. By the way, hint:LocalDateTimeis the wrong type for a loan due date. For a duration, I suggest storing a string in standard ISO 8601 format &java.time.Durationclass.
