二、Why can java return local varieties?

      As we known that the local varieties are stored in the stack(global varieties are in dull),and they will be destroyed when the method excuted.

     then my confuse also conducted,although this local varieties have been destroyed,i understand that the varieties of method in jvm had been clear,then,why could not void method return a local variety?

就是为什么java非空method可以返回method的局部变量,而不是必须是成员变量?
