如何将此 api 结果更改为 Jtable 格式？

Question

能否请一些人帮助我了解如何实现这一目标？

// 查询是通过 API 完成的，然后返回结果，但是它们会被聚集。

try {
    QBC qc = new QBC("user@gmail.com", "P@ssw0rd");
    Vector<Vector<String>> evec = new Vector<>(qc.doQuery("xyz","1", "5","4,5,6","10" ));
     String Results = evec.toString();
     jTextArea2.setText(Results);

    // Need to learn to print this data to table

} catch (Exception e) {
        JOptionPane.showMessageDialog(rootPane, e);
}

---

更改后代码现在可以工作

   try {
            QBC qc = new QBC("user@gmail.com", "password", "https://domain.com/api/", "token");
            Vector<Vector<String>> evec = new Vector<>(qc.doQuery("bjp43iquh","1", "5","4,5,6","10" ));
            Vector<String> columnNames = new Vector<>();
            columnNames.addElement("Column1");
            columnNames.addElement("Column2");
            JTable table = new JTable(evec, columnNames);
            JScrollPane scrollPane = new JScrollPane( table );
            Component add = jInternalFrame1.add( scrollPane );
        }
        catch (Exception e) {
            JOptionPane.showMessageDialog(rootPane, e);
        }
    }           

但是现在得到一个异常>>>>>>> java.lang.Class.CastException:java.util.HaskMap 不能转换为 java.util.Vactor

Vector<Vector<String>> evec = new Vector<>(qc.doQuery("xyz","1", "5","4,5,6","10" ));

您的数据以一个或多个向量的形式返回。这是使用JTable 的完美数据结构。

Vector<String> columnNames = new Vector<String>();
columnNames.addElement("Column1");
columnNames.addElement("Column2");
...
JTable table = new JTable(evec, columnNames);
JScrollPane scrollPane = new JScrollPane( table );
frame.add( scrollPane );
