动手动脑--静态方法中只允许访问静态数据，如何在静态方法中访问类的实例成员

package test.two;

public class jingtaihanshu

{

        int x = 3;

static int  y = 4;

public static void Method()//静态方法

     {  

           System.out.println("实例变量x = " + new jingtaihanshu().x);

           System.out.println("静态变量y = " + y);    

           }

         public static void void main(String[] args)

         {jingtaihanshu.Method();

              jingtaihanshuex = new jingtaihanshu();

                            System.out.println("x = " + ex.x);

         }

}
