Question

有人可以帮助我了解如何实现这一目标吗？

//查询是通过API＆amp;然后返回结果，但它们会聚集在一起。

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);
}

代码现在可以在更改后使用

   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);
        }
    }

但现在获得例外＆gt;＆gt;＆gt;＆gt;＆gt;＆gt;＆gt; java.lang.Class.CastException：java.util.HaskMap无法强制转换为java.util.Vactor＆lt;＆lt;＆lt;＆lt;＆lt;＆lt;＆lt;＆lt;＆lt;＆lt;＆lt;

Answer 1

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

您的数据以矢量或矢量形式返回。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 );

如何将此api结果更改为Jtable格式？
