Java j2me从运行Thread获得结果

Question

HeJ小鼠，

我知道如何将参数传递给Runnable。但是当我的Thread运行时，如何获得进程的结果？

    class Some implements Runnable
{
    int p;
    int endresult = 0;

    public Some(int param){
       p = param;
    }

    public void run(){
        //do something
        endresult += p;
       //Now how to let the method who executed this runnable know that the result is 2;
    }
}

Some s = new Some(1);
Thread t = new Thread(s);
t.start();

当t结束时我想得到'endresult'变量;

Answer 1

您必须等待线程终止，然后才能直接获取字段值：

t.join();
y = s.endresult;

Answer 2

声明endresult volatile并在启动后调用t.join - 当t完成时，这将获得'endresult'值
