java - 如何从线程分配变量

Question

我正在尝试创建一个要返回的变量，该变量指示线程是否成功完成其工作 - 但是，它要求该变量是最终变量，这意味着它不能被重新分配。

为了促进这样的事情需要什么

public static void sendFeedbackEmail(final String user, final FeedbackRating rating,    final String feedbackText, final EmailAddress emailToSendTo) {
    if (rating != null && !StringUtilities.stringEmptyOrNull(user)) {
        boolean result = false;
        Thread emailSender = new Thread(new Runnable() {
            @Override
            public void run() {
                feedbackText = (StringUtilities.stringEmptyOrNull(feedbackText)) ? "N/A" : feedbackText;
                String message = FEEDBACK_MESSAGE.replace("?", rating.getValue())   + user + " Text: " + feedbackText;
                String emailAddress = (emailToSendTo == null) ? USER_FEEDBACK_EMAIL_ADDRESS : emailToSendTo.getValue();
                try {
                    sendVimbaMessage(user, emailAddress, message);
                } catch (MessagingException e) {
                    result = false;
                }
                result = false;
            }
        });
        emailSender.setDaemon(true);
        emailSender.start();
    }
    return false;
}

谢谢

使用 Runnable 执行以下操作:

public class YourClass implements Runnable{

    private boolean yourVariable;

    public YourClass(boolean v){
       yourVariable = v
    }

    public void run(){
       .....
    }

    ........

}

创建线程时，假设您有一个不是最终变量:

boolean nonFinalVariable = true;
Thread t = new Thread(new YourClass(nonFinalVariable));
