    public static void recursion(long a,long b,long c) {

        long e = 1, f= 2,g =3 ,h=4,i=5,k=6,q=7,x=8,y=9,z=10;

    }



    public static void main(String[] args) {

        try {

            recursion(1,2,3);

        } catch (Throwable e) {

            System.out.println("deep of calling = " + count);

            e.printStackTrace();

        }

    }

}

其中 recursion(long a,long b,long c) 方法的棧幀以下，一共13 個long類型的局部變量一共佔用 26 個字
