永中为什么还在用jdk?
class FramAnimal
{
String name;
public void set setName(String n)
{
name = n;
}
public void makeSound()
{
System.out.println(name + "makes a sound ...");
}
}
class Cow extends FramAnimal
{
public void makeSound()
{
System.out.println(name + "gose Mooooooo...");
}
}
class Horse extends FramAnimal
{
public void setName(String n)
{
name = n + "[a Horse]";
}
}
public class Test
{
public static void main(String[] args)
{
Cow c = new Cow();
Horse h = new Horse();
c.setName("Elsie");
h.setName("Mr.Ed");
c.makeSound();
h.makeSound();
}
}
