Question

How do you retrieve a Collection of objects using JDBC.
MORE INFO:
I have created a class i.e. Account class and I want to retrieve all the accounts previously created for accounts in my Mysql database..
my method would retrieve an array of Account instances in the database i.e.
public Vector retrieveAccounts();

Answer 1

Connection con = null;
ArrayList accounts = new ArrayList();
try{
  con = DriverManager.getConnection(...);
  PreparedStatement ps = con.prepareStatement("select * from accounts");
  Resultset rs = ps.executeQuery();
  while (rs.next()) {
    Account account = new Account(rs.getString(1), rs.getString(2), ...);
    accounts.add(account);
  Account[] account_array = new Account[accounts.size()];
  accounts.toArray(account_array);
catch (SQLException sqle) {
   sqle.printStackTrace();
finally {
  if (con != null) {
    con.close();
}should pretty much to what you want, you will obviously need to change it so that, a) the SQL query is correct and b) the Account class is correct and c) the correct values are taken from the result set to create an account.
