    static Runnable runnable = new Runnable() { @Override public void run() {
            System.out.println(Thread.currentThread().getName()+":开始");
            DeadThread deadThread = new DeadThread();
            System.out.println(Thread.currentThread().getName()+":结束");
        }
    };
    public static void main(String[] args) {
        Thread t1 = new Thread(runnable);
        Thread t2 = new Thread(runnable);
        t1.start();
        t2.start();
    }
}
class DeadThread{
    static {
        if(true) {
            System.out.println(Thread.currentThread().getName()+":lllllll");
            while (true){
