java - 如何从 groupbutton 中检索 jbuttons 文本

Question

我正在尝试获取所选按钮的文本名称并将其发送到我的数据库。有没有办法让buttonGroup 传递所选按钮名称的文本？因为我想将选定的按钮名称插入到交易表中。

 try {
      conn = getConnection(); 
      String Transaction = "INSERT  INTO Transaction"
                + "(Currency_type, currency_Amount,Local_Amount,Rate,Tran_type) VALUES"
                + "(?,?,?,?)";

      pst = conn.prepareStatement(Transaction); // create a statement
      pst.setObject(1,DisplayL.getText()); // set input parameter 1
      pst.setObject(2,txt_select.getText()); // set input parameter 2
      pst.setObject(3,txt_amount.getText()); // set input parameter 1
      pst.setObject(4,txt_rate.getText()); // set input parameter 2
      pst.setObject(5,buttonGroup2); // set input parameter 2

      pst.execute();// execute update statement
    } catch (Exception e) {
      e.printStackTrace();
    } finally {
            try {
                pst.close();
            } catch (SQLException ex) {
                Logger.getLogger(connectnm.class.getName()).log(Level.SEVERE, null, ex);
            }
            try {
                conn.close();
            } catch (SQLException ex) {
                Logger.getLogger(connectnm.class.getName()).log(Level.SEVERE, null, ex);
            }
    }

 ButtonModel btnModel = buttonGroup2.getSelection();
if(btnModel !=null)
