interface Runner{
int ID = 1;
void run();
}

interface Animal extends Runner{
void breathe();
}

abstract class LandAnimal implements Animal{
public void breathe(){
System.out.println("LandAnimal");
}
}

public class TestInterface_01 {
public static void main(String[] args) {
LandAnimal L = new LandAnimal();
L.breathe();
}
}
抽象类怎么实现接口定义的部分方法呀?
我这个编译不能通过呢?那错了呢?

谢谢,千里冰封大兄弟!
还有个问题呀
为什么我的"interface Runner" 前面不能加"public"呢?一加就出错呢?
我看有的书上,interface前面加public了呀

interface Runner{
int ID = 1;
void run();

}

interface Animal extends Runner{
void swim();
}

abstract class LandAnimal implements Animal{
public abstract void run();
//public abstract void swim();

}
class Cat extends LandAnimal{
public void run() {System.out.println("陆地动物会跑");}
public void swim() {System.out.println("陆地动物会游泳的少");}
}

public class TestInterface_01 {
public static void main(String[] args) {
LandAnimal c = new Cat();
c.run();
}
}
这样用"abstract"应该对了吧.
