public class DeadThreadTest {

    public static void main(String[] args) {
        Runnable r = new Runnable() {
            @Override
            public void run() {
                System.out.println(Thread.currentThread().getName() + "开始");
                //这一步的目的就是为了加载类
                DeadThread dt = new DeadThread();
                System.out.println(Thread.currentThread().getName() + "结束");
            }
        };

        Thread t1 = new Thread(r, "线程1");
        Thread t2 = new Thread(r, "线程2");

        t1.start();
        t2.start();
    }

}

class DeadThread {
    static {
        System.out.println(Thread.currentThread().getName() + "初始化当前类");
