如何在 jtable 中插入这组代码。问题是当我md.addElement(id); addElement()

时，它会显示一个红色下划线。

public class hospitalisation extends javax.swing.JFrame {

DefaultTableModel md = new DefaultTableModel();

public hospitalisation() {
    initComponents();

    hospitalisationtable.setModel(md);
    buttonGroup1.add(male);
    buttonGroup1.add(female);

}
private void addBtnActionPerformed(java.awt.event.ActionEvent evt) {                                       
    String id = "id: " + idtxt.getText();
    String name = "name: " + nametxt.getText();
    String sex = "sex:";
    String address = "address: " + addresstxt.getText();
    String sdate = "sdate: " + sdatetxt.getText();
    String room = "room: " + cs_room.getSelectedItem().toString();
    String father = "father: " + fathertxt.getText();
    String phone = "phone: " + phonetxt.getText();
    String age = "age: " + agetxt.getText();
    String edate = "edate " + edatetxt.getText();

    if (female.getModel().isSelected() == true)
        sex += female.getText();
    else if (male.getModel().isSelected() == true)
        sex += male.getText();

    md.addElement(id);
    md.addElement(name);
    md.addElement(sex);
    md.addElement(address);
    md.addElement(sdate);
    md.addElement(room);
    md.addElement(father);
    md.addElement(phone);
    md.addElement(age);
    md.addElement(edate);        
}

这是我的代码

它在addElement（）上显示了一个红色下划线 这是因为您可以看到here该类中没有DefaultTableModel.addElement(String) ...

考虑一下看看文档，然后考虑一种给定的方法像

addColumn(Object columnName)
addColumn(Object columnName, Object[] columnData)
addColumn(Object columnName, Vector columnData)
addRow(Object[] rowData)
addRow(Vector rowData)
