Question

package jdbcex;
import java.sql.*;
public class JdbcDmlEx {

public static void main(String[] args) {
    String[] arr;
    arr = new String[3];

    try {
    Class.forName("net.ucanaccess.jdbc.UcanaccessDriver");
        Connection conn = DriverManager.getConnection("jdbc:ucanaccess://C:\\access\\PersonInfo.accdb");

    Statement st = conn.createStatement();

    //execute the query / DML

    String addVar = arr[0];
    String nameVar = arr[1];

    String sql = "UPDATE Person" +
                 "SET address =  '" + addVar + " ' " +
                 "WHERE name = '" + nameVar + " ' " ;

    PreparedStatement pstmt = conn.prepareStatement(sql);

    int num = pstmt.executeUpdate();

// process the results of the query
System.out.println(num + " records updated");

conn.close();

    }catch(Exception sqlEx) {
        System.out.println(sqlEx);
    }
}//end of main
}//end of class

无法理解问题所在。有人可以帮忙吗？
