Count Number of Records in Oracle Database Table

Question

Please help me to see if I "set" and "return" the number of records in my database table correctly (I am using the Oracle 9i):
   public int getNumberOfRecipientBeans() throws AssertionException, DatabaseException
      Connection conn = null;
      PreparedStatement stmt = null;
      String query = "SELECT count(*) FROM ContactEntry WHERE ContactTypeID = 6";
      ResultSet rs = null;
      try
         conn = DBConnection.getDBConnection();
         stmt = conn.prepareStatement( query );
         rs = stmt.executeQuery();
         // do I have to set anything here?
         if ( !rs.next() )
            throw new AssertionException("Assertion in servuce.getNumberOfRecipients");
          // Am I returning the counts here?
          return rs.getInt( 1 );
      catch( SQLException sqle )
         sqle.printStackTrace();
         throw new DatabaseException( "Error executing SQL in service.getNumberOfRecipients." );
      finally
         if ( conn != null )
            try
               stmt.close();
               stmt = null;
               conn.close();
            catch( Exception Ex )
               System.out.println( "Problem occurs while closing " + Ex );
            conn = null;

Answer 1

public class MyE extends Exception {
    public MyE() {
        super(); // this line is not necessary. An empty method would suffice
    public MyE(String msg) {
        super(msg);
    // Check the API for Exception or Throwable--I may have the args backward
    public MyE(String msg, Throwable cause) {
        super(msg, cause);
    public MyE(Throwable cause) {
        super(cause);
// Replace the log_warn() calls with appropriate logging calls for your context
public class Closer {
    public static final void close(ResultSet closeMe) {
        if (closeMe != null) {
            try {
                closeMe.close();
            catch (Throwable th) { log_.warn("Closing " + closeMe + ": ", th); }
    public static final void close(Statement closeMe) {
        if (closeMe != null) {
            try {
                closeMe.close();
            catch (Throwable th) { log_.warn("Closing " + closeMe + ": ", th); }
    public static final void close(Connection closeMe) {
        if (closeMe != null) {
            try {
                closeMe.close();
            catch (Throwable th) { log_.warn("Closing " + closeMe + ": ", th); }
    public static final void close(ResultSet rs, Statement stmt, Connection con) {
        close(rs);
        close(stmt);
        close(con);
}
