已知有如下程序: class Father{ Father(){System.out.print("Father call\t");} void print(){System.out.print("Father print\t");} } public class Demo extends Father { Demo(){System.out.print("Demo call\t");} void print(){System.out.print("Demo print\t");} public static void main(String args[]){ Father d=new Demo(); d.print(); } } 则以下输出结果正确的是:( )
