There are some possible solutions:

<ol>
<li>It exists hardware, that is able to
execute Java-bytecode.</li>
<li>Also you can compile Java-code to
native code with different
compilers.</li>
<li>Finally you can have a mini-loader, that
starts the rest of the process in
Java.</li>
</ol>

Neither of this solutions is easy or does make too much sense. But possible - yes.

For completeness: <a href="http://jnode.org/" rel="nofollow noreferrer">JNode</a> is a project targeting to create a PC-Operating-system in Java.

Also answers to <a href="https://stackoverflow.com/questions/683701/is-it-possible-to-code-a-device-driver-in-java">this question</a> may be helpful. It ask for device-drivers in Java, and that's not completely the same question, but some of the solutions presented in the answers may be helpful with your question too.

blocks|key|4541881|text|它当然是的。一个更好的问题是，它是否实用，以及与现有方法相比，它是否会提供任何值得花费实施时间的好处。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|4541882|entityMap^0|0^^$0|@$1|2|3|4|5|6|7|D|8|@]|9|@]|A|$]]|$1|B|3|-4|5|6|7|E|8|@]|9|@]|A|$]]]|C|$]]

Of course it is. A better question would be whether it is practical or not, and if it would offer any benefits worth the implementation time compared to existing methods.

blocks|key|4541928|text|我不想直截了当地说不，因为我确信，如果我这样做了，有人会想出一种方法来做这件事，但这肯定是非常困难的(可能是徒劳的)。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|4541929|对于在JVM上运行的Java，您需要在本地引导足够数量的OS，然后切换到java会有点浪费时间(除了增加复杂性之外，它实际上不会完成太多事情)。|4541930|有一些设备可以在可能的情况下“本机”运行字节码，但我认为大多数情况下这是不可行的。|4541931|entityMap^0|0|0|0^^$0|@$1|2|3|4|5|6|7|H|8|@]|9|@]|A|$]]|$1|B|3|C|5|6|7|I|8|@]|9|@]|A|$]]|$1|D|3|E|5|6|7|J|8|@]|9|@]|A|$]]|$1|F|3|-4|5|6|7|K|8|@]|9|@]|A|$]]]|G|$]]

I don't want to say an outright no, because I'm sure if I did someone would come up with a way of doing it, but this would certainly be VERY difficult (and possibly fruitless).

For Java to run on a JVM, you'd need to natively bootstrap a sufficient amount of the OS natively that then switching to java would be a bit of a waste of time (it really wouldn't accomplish much other than adding complexity).

There are devices that can "natively" run bytecode where it's conceivably possibly, but I don't think that's viable most of the time.

blocks|key|226555|text|@Mnementh提到了JNode。根据记录，JNode使用GRUB作为其引导加载程序。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|226556|我同意@Mnementh的观点，即在Java中实现引导加载程序在技术上是可行的，尽管可能很困难。但我对操作员的问题是“你为什么要这样做？”我不明白这是什么意思。|226557|entityMap^0|0|0^^$0|@$1|2|3|4|5|6|7|F|8|@]|9|@]|A|$]]|$1|B|3|C|5|6|7|G|8|@]|9|@]|A|$]]|$1|D|3|-4|5|6|7|H|8|@]|9|@]|A|$]]]|E|$]]

@Mnementh mentioned JNode. For the record, JNode uses GRUB as its bootstrap loader. 

I agree with @Mnementh that implementing a boot loader in Java would be technically possible though probably difficult. But my question to the OP is "why would you want to do it?". I don't see the point.

Normally boot strap loaders are written using assembly languages.
Is it possible to dot it using java with native interface.

通常，引导加载程序是使用汇编语言编写的。有没有可能用带有本机接口的java来打点它呢？
