继承extends:

继承extends:

public class Person {

private String name;

private int age;

 

public Person() {

 

}

public Person(String name,int age) {

this.name=name;

this.age=age;

}

public void setName(String name) {

this.name=name;

}

public String getName() {

return name;

}

public void setAge(int age) {

this.age=age;

}

public int getAge() {

return age;

}

}

public abstract class Sport extends Person{

public Sport() {

 

}

 

public Sport(String name,int age) {

super(name,age);

}

public abstract void study();

}

接口interface:

public interface English {

public abstract void speak();

}

public class PingPongSport extends Sport implements English{

public PingPongSport() {

 

}

public PingPongSport(String name,int age) {

super(name,age);

}

 

@Override

}

 

@Override
