A方法：
List<User> userList = new ArrayList<>();
User user = null;
for (int i = 0; i < 10; i++) {
user = new User("username_" + i, "password_" + i);
userList.add(user);
}

B方法：
List<User> userList = new ArrayList<>();
for (int i = 0; i < 10; i++) {
User user = new User("username_" + i, "password_" + i);
userList.add(user);
}
