private String name;
public Animal() {
}
public Animal(String name) {
this.name=name;
}
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
public abstract void call();
}
class Animalbass{
Animal[] dolphins=new Animal[4];
}程序代码：
public class Dog extends Animal implements Refund {
private int refund;
public Dog(){
}
/*public Dog(String name,int refund){
super(name);
this.refund=refund;
}*/
public int getRefund() {
return refund;
}
public void setRefund(int refund){
this.refund = refund;
}
public void refund() throws Exception{
if(refund!=4){
throw new Exception("狗狗的腿是四肢");
}
}
@Override
public void call() {
System.out.println("汪汪。。。");
}
}
程序代码：

public Dolphins(String name){
super(name);
}
public void call() {
System.out.println("海豚之音。。。");

this.refund = refund;
}
@Override
public void refund() throws Exception {
// TODO Auto-generated method stub
