一直对多线程操作一直半解，在网上看了很多贴，写个小demo算是小小的收获吧:-)
public class TestThread {
private static int number = 1;
static Thread NumberThread;
static Thread MonitorThread;
public static void main(String[] args){
NumberThread = new Thread(new Runnable() {
public void run() {
while(true){
try {
number++;
System.out.println("this is the number: "+number);
} catch (Exception e) {
e.printStackTrace();
return;
}
}
}
});
MonitorThread = new Thread(new Runnable() {
public void run() {
System.out.println("Thread MonitorThread");
synchronized(this) {
while(true){
try {
if(number > 50){
System.out.println("number is > 50 now");
NumberThread.stop();
break;
}
} catch (Exception e) {
e.printStackTrace();
return;
}
}
}
}
});
NumberThread.start();
MonitorThread.start();
}
}
运行结果如下：
this is the number: 2
Thread MonitorThread
this is the number: 3
this is the number: 4
this is the number: 5
this is the number: 6
this is the number: 7
