I'm trying to create a registration menu but I'm having trouble creating the objects in an accessible array. Super class constructor:
Login(String fn, String ln, String acc, String by, String pw){
firstName = fn;
lastName = ln;
account = acc;
birthYear = by;
password = pw;
}
In the super class I created an array of type Login
. In the child class Register
, I'm trying to create objects in the array. My registration menu has several fields to be filled in. I want an error message to pop up when the fields are empty and when the password fields do not match.
JButton btnRegister = new JButton("Register");
btnRegister.addActionListener(new ActionListener() {
public void actionPerformed(ActionEvent arg0) {
boolean match = false;
while (match == false){
if (textField_4.getText().equals(textField_5.getText())){
try{
for (int i = count; i<= list.length;i++){
list[i] = new Login(textField.getText(),textField_1.getText(),textField_2.getText(),textField_3.getText(),textField_4.getText());
count++;
match = true;
}}
catch (Exception e){
JOptionPane.showMessageDialog(null, "Fields are empty", "Error", JOptionPane.INFORMATION_MESSAGE);
System.out.println(e);
break;
}
}
else
match = false;
JOptionPane.showMessageDialog(null, "Password fields do not match!", "Error", JOptionPane.INFORMATION_MESSAGE);
break;
}
}
});
I have gotten the password mismatch feature to work but I currently get a ArrayIndexOutOfBounds
thrown when I try to enter all of the fields and create an object. How do I resolve this issue? Thank you in advance.
The culprit is most likely these two lines
for (int i = count; i<= list.length;i++){
list[i] = ...
Trying to access " list[list.length] " will give you an ArrayIndexOutOfBounds , since indeces start at 0, so list 's last index is list.length-1 ;
Change from " i<= list.length " to " i < list.length ".
