我的问题如下，我看到当我编辑注册表时，它工作，注册表更改，但当我想注册一个新用户，它属于编辑条件，它编辑我是的注册表信息之前更改，不要离开注册新用户。
负责验证您是否正在编辑的变量。
Private int codeEdit = 0;
负责在表中提取用户代码的方法。
JButton button_3 = new JButton ( "Edit");
Button_3.addActionListener (new ActionListener () {
Public void actionPerformed (ActionEvent e) {
TabbedPane.setSelectedIndex (0);
// Variable responsible for capturing the selected line
Int selectedRow = -1;
// Search for selected row and store in variable
// rowSelected (tr)
//
selectedRow = table.getSelectedRow();
// Validate if a row was selected
If (selectedRow >= 0) {
// Stores information from the first row column
// selected (td)
// column 0 employee code
Int code_employee = (int) table.getValueAt(selectedRow, 0);
FindEmployee(code_employee);
} Else {
JOptionPane.showMessageDialog (null, "Select a" + "line to change Employee!");
}
}
});
接收员工代码作为参数的方法，将用户信息放在注册屏幕上进行更改。
// receives as parameter the employee code
Protected void searchEmployee (int cod_employee)
Control.Employees employees = new control.Employees();
// foreach loop that traverses the arraylist referencing the employee's code
For (Employees emp: employees.listEmployees(cod_employee + "", 1)) {
// Set information on the registration screen
Name.setText (emp.getName ());
Email.setText (emp.getEmail ());
Address.setText (emp.getAdress());
Phone.setText (emp.getTelephone());
Cpf.setText (emp.getCpf_employee());
// Variable that receives the value of the user code
// important for change
codeEdit = emp.getCode_employee();
}
register.setVisible (true);
Listing.setVisible (false);
}
负责保存或更换员工的方法。
Protected void save () {
// Capture information that the user entered
String employee_name = name.getText();
String cpf_employee = cpf.getText();
String address_employee = address.getText();
String email_employee = email.getText();
String phone_employee = phone.getText();
String employee_password = password.getText();
String rep_password_employee = repemployee.getText();
If (email_employee.equals ( "") && cpf_employee.equals ( "") && phone_employee.equals ( "") && name_employee.equals ( "")) {
JOptionPane.showMessageDialog (null, "Fill in the fields");
} Else if (! rep_password_employee.equals (employee_password)) {
JOptionPane.showMessageDialog (null, "Passwords are different");
// validate if passwords are equal
} Else if (address_employee.equals ( "")) {
JOptionPane.showMessageDialog (null, "The Address field is Required!");
}
// Creating the object
Employees emp = new Employees ();
emp.setName (name_employee);
emp.setEmail (email_employee);
emp.setTelephone (phone_employee);
emp.setPassword (employee_password);
emp.setAdress(address_employee);
emp.setCpf_employee(cpf_employee);
emp.setCode_employee(codeEdit);
Control.Employees maintenance = new control.Employees();
// validate if we are registering or editing the records
If (codeEdit == 0) {
Maintenance.insert(emp);
} Else {
Maintenance.change (emp);
}
CleanInformations ();
TabbedPane.setSelectedIndex (1);
}
}

保存员工类控制包的方法
Public void insert (dao.Employees emp) {
If (emp! = Null) {
// DB connection variable
Java.sql.Connection conn = null;
try {
Conn = ConnectDB.connectionDB ();
Java.sql.PreparedStatement pstm;
Pstm = conn.prepareStatement (INSERT);
Pstm.setString (1, emp.getCpf_employee());
Pstm.setString (2, emp.getEmail ());
Pstm.setString (3, emp.getPassword ());
Pstm.setString (4, emp.getName ());
Pstm.setString (5, emp.getAddress ());
Pstm.setString (6, emp.getTelephone ());
// Send to database
Boolean test;
Test = pstm.execute ();
// Validate insertion in the database
If (! Test) {
JOptionPane.showMessageDialog (null, "Registered Successfully!");
} Else {
JOptionPane.showMessageDialog (null, "Error registering the employee!");
}
// Close the connection to the database
ConnectDB.CloseClose (conn);
} Catch (Exception e) {
JOptionPane.showMessageDialog (null, "Error registering the official!");
}

}
更改员工类包控制的方法
// parameter object of the.functional
Public void change (dao.Employee emp) {

// prepare the query

Pstm.setString (6, func.getPassword ());
Pstm.setInt (7, func.getCode_employee());
// Send to database
Boolean test;
Test = pstm.execute ();
// Validate insertion in the database
If (! Test) {
JOptionPane.showMessageDialog (null, "Successfully changed employee!");
} Else {
JOptionPane.showMessageDialog (null, "Error while changing the official!");
}
// Close the connection to the database
ConnectDB.CloseClose (conn);
} Catch (SQLException e) {
