在方法中声明 volatile变量报错：Modifier 'volatile' not allowed here

不知道是不是就我这么干了，网上居然搜不到

随便写了段多线程的练习代码，想要使用volatile关键字，于是：

...
public static void main(String[] args) {

	volatile int count = 0;
	...
}

IDE报错提示 Modifier ‘volatile’ not allowed here
不解，查，得：

Local variables live on the stack; and of course, when you invoke the same method twice, they have all their local variables on their individual stacks.
volatile only makes sense when multiple threads would be writing to the same memory location (on the heap).
Which makes absolutely no sense for local variables from within the body of a method!

大意就是局部变量(count)保存在栈中，方法每次调用栈都不一样，这样该volatile便没有意义。

怎么说呢，我随手写个练习想在main方法加个volatile也是个很自然的需求不是？
