package threadmodle;
import java.util.HashMap;
import java.util.Map;
import java.util.UUID;
public class ThreadModle {
public static void main(String[] args) throws InterruptedException {
final Map<String, String> map = new HashMap<String, String>();
Thread t = new Thread(new Runnable(){
@Override
public void run() {
System.out.println("Run threadID: " + Thread.currentThread().getId());
for (int i = 0; i < 10000; i++){
new Thread(new Runnable(){
@Override
public void run() {
map.put(UUID.randomUUID().toString(), UUID.randomUUID().toString());
System.out.println("Run work threadID: " + Thread.currentThread().getId());
}
}, "test" + i).start();;
}
}
});
System.out.println("Main threadID: " + Thread.currentThread().getId());
t.start();
t.join();
}
}
