public class Fabric extends Thread{
public static void main(String args[]){
Thread t = new Thread(new Fabric());
Thread t2 = new Thread(new Fabric());
Thread t3 = new Thread(new Fabric());
t.start();
t2.start();
t3.start();
}
public void run(){
System.out.println(Thread.currentThread().getName() + ": " + i);
}
}このコードの出力は1,3,5(無秩序)です.
ただし、スレッド名を指定すると1,2,3になります.
public class Fabric extends Thread{
public static void main(String args[]){
Thread t = new Thread(null, new Fabric(), "1");
Thread t2 = new Thread(null, new Fabric(), "2");
Thread t3 = new Thread(null, new Fabric(), "3");
t.start();
t2.start();
t3.start();
}
public void run(){
System.out.println(Thread.currentThread().getName() + ": " + i);
}
}
