试试看，一道充满陷阱的java题目

Question

本人最近在学JVM，学习GC时，发现一道不错的题目，故此拿出来与大家一起分享。

 public class ReliveObj {
    public static ReliveObj obj;
    @Override
    protected void finalize() throws Throwable {
        super.finalize();
        obj = this;
    }
    @Override
    public String toString() {
        return "I am a ReliveObj";
    }

    public static void main(String[] args) throws InterruptedException {
        obj = new ReliveObj();
        System.out.println(obj);
        obj = null;
        System.out.println(obj);
        System.gc();
        TimeUnit.SECONDS.sleep(1);
        System.out.println(obj);
        obj = null;
        System.out.println(obj);
        System.gc();
        TimeUnit.SECONDS.sleep(1);
        System.out.println(obj);
    }
}

问输出是什么，大家不妨试下，看看能不能做对，稍后公布答案
