下列程序的运行结果是 class Demo{       private String name;         Demo(String name){this.name = name;}        private static void show(){            System.out.println(name)       }       public static void main(String[] args){              Demo d = new Demo(“lisa”);            d.show();       }  } A.
输出lisa B.
输出null C.
输出name D.
编译失败,无法从静态上下文中引用非静态变量name
