怎么返回一个变量的地址？# Java - 爪哇娇娃

1 楼
前两天看到一个面试题，怎么确定stack grow的方向，是从高地址到低地址，还是相反
。这个问题用C很容易，写两个nested function call, 在每个里面分配一个变量，然
后检查指针就行了。Java 有什么办法呢？

Don't know how to do this in Java - calling a JNI function from two nested
Java methods? What's the point anyway?

The interpreter stack is different from the native method stack.
The interpreter stack (1) can be allocated on heaps, may be expandable,
and need not to be contiguous.
The native method stack (2) is a C calling stack, not expandable.
So using JNI would only provide you C-calling stack information.
However, maybe you could inspect the VM to generate the necessary
information for stack. Throwable.fillStackTrace() (spelling?) is
a native function call. If you have the source code of that piece
