如何使BufferedReader产生？

Question

Let's say I've got two threads running. Thread #1 reads System.in like this:

BufferedReader br = new BufferedReader(new InputStreamReader(System.in));

String s;
while (true) {
    s=br.readLine();
    if(s!=null)
        doSomethingWithThat(s);
    }
}

I also have Thread #2 that performs some operations, among others needs to read System.in when certain things happens (that in general are not triggered by Thread #1 .)

Is it possible to somehow interrupt Thread #1 so that br.readLine() would return null and #Thread #2 could read System.in ?

Answer 1

Added this before readLine() & did the trick

while(System.in.available()<=0 || yield)
    Sleep.millis(420);
