Java - 尚不支持

Question

这是我的代码

登录框架：

  try{
  Class.forName("java.sql.Driver");
  Connection con=(Connection) DriverManager.getConnection("jdbc:mysql://localhost/FoodFrame", "root", "valli99");
  Statement stmt=(Statement) con.createStatement();
  String username=jTextField3.getText();

  String password=new String(jPasswordField1.getPassword());
  String Email=new String(jTextField5.getText());

  if("".equals(username) || "".equals(password) || "".equals(Email))
  JOptionPane.showMessageDialog(null, "Please fill in all the fields");

  else {
  String query="select * from User where EmailId='"+jTextField5.getText()+"'or Username='"+jTextField3.getText()+"';";
  ResultSet rs=(ResultSet) stmt.executeQuery(query); 

  if(rs.absolute(1)){
      Toolkit.getDefaultToolkit().beep();
      jTextField3.setText("");
      jTextField5.setText("");
      jPasswordField1.setText("");

        if(Email.equals(rs.getString(4)))
      JOptionPane.showMessageDialog(null, "This email has already been registered");
        else if(rs.absolute(2)){
            if(Email.equals(rs.getString(4)))
      JOptionPane.showMessageDialog(null, "This email has already been registered");}
        else 
      JOptionPane.showMessageDialog(null, "This username already exists");    
  }   

   boolean hasLetter = false;
    boolean hasDigit = false;

    if (password.length() >= 8) {
        for (int i = 0; i < password.length(); i++) {

            char x = password.charAt(i);

            if (Character.isLetter(x)) {
               hasLetter = true;}

               else 
                if (Character.isDigit(x)) {
                   hasDigit = true;}

        if(hasLetter && hasDigit){
              break;
            }

        }
    if (hasLetter && hasDigit) {
        Statement stm=(Statement) con.createStatement();
            String qy="insert into user(Username,Password, EmailID) values('"+username+"', '"+password+"', '"+jTextField5.getText()+"');";
            stm.executeUpdate(qy);  
            JOptionPane.showMessageDialog(null, "You have successfully created an account. Please enter some more details about yourself");
            String Username=jTextField3.getText();
new Details(Username).setVisible(true);
new Details().setVisible(true);

dispose();   

        jTextField3.setText("");
        jTextField5.setText("");
        jPasswordField1.setText("");


        } else {
            JOptionPane.showMessageDialog(null, "Password not strong.It has to be 8 characters log and should contain letters & digits");
        }
    } else {
        Toolkit.getDefaultToolkit().beep();
        JOptionPane.showMessageDialog(null, "Password should have at least 8 characters");
        jPasswordField1.setText("");

    }

 } 

  rs.close();
  stmt.close();
  stm.close();
  con.close();
   }


catch(Exception e){
JOptionPane.showMessageDialog(null, e.getMessage()); }// TODO add your handling code here:
}                                                    

详细信息框架

    public Details(String abc) {
    initComponents();
    jLabel5.setText(abc);

private void jButton2ActionPerformed(java.awt.event.ActionEvent evt) {                                         


String Restriction = " ";
if(jCheckBox1.isSelected())
    Restriction =Restriction+" "+"Egg";
if(jCheckBox2.isSelected())
    Restriction =Restriction+" "+"Dairy";
if(jCheckBox3.isSelected())
    Restriction =Restriction+" "+"Seafood";
if(jCheckBox4.isSelected())
    Restriction =Restriction+" "+"Poultry";
if(jCheckBox5.isSelected())
    Restriction =Restriction+" "+"Nuts";
if(jCheckBox6.isSelected())
    Restriction =Restriction+" "+"Gluten-free";
String age = new String((String) jComboBox1.getSelectedItem());

 try{
     Class.forName("java.sql.Driver");
     Connection con=(Connection) DriverManager.getConnection("jdbc:mysql://localhost/foodframe", "root", "valli99");
     Statement stmt=(Statement) con.createStatement();
     String query="Update user set Name='"+jTextField1.getText()+"', Age='"+age+"', Restrictions='"+Restriction+"', Dislikes_Allergies='"+jTextArea1.getText()+"' where Username='"+jLabel5.getText()+"';";
     stmt.executeUpdate(query);
     String user=jLabel5.getText();
     new Home_Page(user).setVisible(true);
     new Home_Page.setVisible(true);
     dispose();


     rs.close();
     stmt.close();
     con.close();
 }
 catch(Exception e){
     JOptionPane.showMessageDialog(null, e.getMessage());
 }

该错误是由throw new UnsupportedOperationException("Not supported yet.");语句引起的，我已将其替换为其他内容。然而，我收到错误消息＆＃34;尚未支持＆＃34;点击按钮后。请帮忙摆脱这条消息。感谢。

编辑：我添加了另一个链接到我的详细信息框架的框架。详细信息框架是显示错误消息的位置。其他帧很好。
