How to interrupt a thread blocked by some socket IO operations without closing

I really want to know how to interrupt a thread blocked by some I / O operation? I / O is through socket, I don't want to close () socket

I try to use thread Interrupt() to interrupt the thread, but failed

Thread blocked by IO operation:

void run(){
    byte[] data=new byte[1024];
    in.read(data);//blocked!
}

Thread used to interrupt a blocked thread (not working):

void run(){
    blockedThread.interrupt();//no success!
}

Solution

When getting sockettimeoutexception, set a short read timeout on the socket and loop, and check thread every time isInterrupted(). Use thread Interrupt() to interrupt the thread
