考虑以下代码 -
class MyThread extends Thread {
private int x = 5;
public void run() {
synchronized (this) // <-- what does it mean?
{
for (int i = 0; i < x; i++) {
System.out.println(i);
}
notify();
}
}
}
class Test {
public static void main(String[] args) {
MyThread m = new MyThread();
m.start();
synchronized (m) {
try {
m.wait();
} catch (InterruptedException e) {
}
}
}
}
在上面的例子中,线程 m 是否获得了自己的锁?
