Question

I have a Swing GUI where I am restricting the user registration so that the username and the password cannot be the same. I am using JoptionPane for the task with the following code:

public void actionPerformed(ActionEvent e) {
String username = tuser.getText();
String password1 = pass1.getText();
String password2 = pass2.getText();
String workclass = wclass.getText();
Connection conn = null;

try {
    if(username.equalsIgnoreCase(password1)) {
       JOptionPane.showMessageDialog(null,
           "Username and Password Cannot be the same. Click OK to Continue",
           "Error", JOptionPane.ERROR_MESSAGE); 
       System.exit(0);
    }
...

The problem is that I had to use System.exit(0); without it, the next code was getting executed. Even after the JOptionPane poped up, the registration was succeeding. I do not need the system to exit, but I need the user to be kept on the registration page after the validation. What is the best way to do this? Is there other convenient ways of doing this rather than using the JOptionPane?

Answer 1

Replace

System.exit(0);

with

return;

if you do not want the rest of the method to be performed
