I have 4 textboxes, 2 of them being password boxes (for the user to confirm their password).
Here’s my code:
public void actionPerformed(ActionEvent arg0) {
String username = usernameField.getText();
String emailAddress = emailField.getText();
String password1 = passwordField1.getText();
String password2 = passwordField2.getText();
if (password1 != password2) {
[code here]
}
}
How can I make it so that if the passwords aren’t equal it stops the rest of the code in that method from executing?
Answer
There is a significant problem before you can do this: you have to compare strings correctly. Then, you can decide what to do if they’re false. Ultimately, using return in a void method is acceptable if you only want to return.
if (!password1.equals(password2)) {
// [code here]
}
However, the better approach would be to do a simple blanket check, and avoid the early return – if the passwords are valid, then do operations in the scope of that block. The fall-through case would exit the method early.
public void actionPerformed(ActionEvent arg0) {
String username = usernameField.getText();
String emailAddress = emailField.getText();
String password1 = passwordField1.getText();
String password2 = passwordField2.getText();
if (password1.equals(password2)) {
// code on success here
}
}
