Java j2me从运行线程获取结果
Hej，
我知道如何将参数传递给 Runnable。但是当我的线程运行后，如何获取进程的结果呢？
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 完成时，我想获得 'endresult' 变量；
Hej,
I know how to pass parameters to a Runnable. But when my Thread has run, how to get the result of the process?
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();
when t is finished i want to get the 'endresult' variable;

您必须等待线程终止，然后才能直接获取字段值：
You have to wait for your thread to terminate and then you can get the field value directly:
声明 endresult
volatile并在启动后调用t.join- 当 t 完成时，这将获得“endresult”值declare endresult
volatileand invoket.joinafter it was started - when t is finished this will get the 'endresult' value
