Question

I’m iterating an ArrayList of clients named clientList that contains clients from the class Client (user,pass)

ArrayList<Client> clientList= new ArrayList<Client>();

Here’s the iteration. I want to stop the iteration if it founds a given user (user) and if the password (pass) matches:

            for (Client c : clientList) {
                userA = c.getUser();
                if (userA.equals(user)) {
                    passA = c.getPassword();
                    if (passA.equals(pass)) {
                        loginOK = true;
                        found= true;
                    }

I was trying the following while (found == false) but it’s get stucked if it doesnt find an user on the ArrayList:

        while (found == false) { /
            for (Client c : clientList) {
                userA = c.getUser();
                if (userA.equals(user)) {
                    passA = c.getPassword();
                    if (passA.equals(pass)) {
                        loginOK = true;
                        found= true;
                    }
                }
            }
        }

I’d write it this way:

while (!found) { 
    for (Cliente c : clientList) {
        userA = c.getUser();
        if (userA.equals(user)) {
            passA = c.getPassword();
            if (passA.equals(pass)) {
                loginOK = true;
                found= true;
                break;
            }
        }
    }
}

My guess is that you didn’t override equals and hashCode in your Cliente class or it’s not correct.
