public class Oracle {
public static void main(String[] args) {

   String url = "jdbc:oracle:thin:@localhost:1521:xe";
   Connection conn = DriverManager.getConnection(url, "sa", "abc");
   String sql = "select * from /"T_Person/"";
   PreparedStatement psStatement = conn.prepareStatement(sql);
   ResultSet rSet = psStatement.executeQuery();
   System.out.println("/tOracle查询数据");
   while (rSet.next()) {
    System.out.println(rSet.getString(1) + "/t" + rSet.getInt(2)
      + "/t" + rSet.getString(3));
   }

  } catch (InstantiationException e) {
   e.printStackTrace();
  } catch (IllegalAccessException e) {
   e.printStackTrace();
  } catch (ClassNotFoundException e) {
   e.printStackTrace();
  } catch (SQLException e) {
