在Java中停止ArrayList的迭代 [英] Stopping an iteration of an ArrayList in Java

问题描述

我正在迭代 ArrayList 名为 clientList 的客户端，其中包含来自类客户端的客户端（用户，通过）

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

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

这是迭代。我想停止迭代，如果它找到一个给定的用户（用户），如果密码（传递）匹配：

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;
                    }

我正在尝试以下 while（found == false）但是如果它没有在ArrayList上找到用户就会被卡住：

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;
                    }
                }
            }
        }

推荐答案

我这样写：

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;
            }
        }
    }
}

我的猜测你没有在你的 Cliente 类中覆盖equals和hashCode，或者它不正确。

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