面向对象之接口的代码练习：学生老师案例加入抽烟功能 - 黑马程序员技术交流社区

//老师学生案例，加入抽烟的功能
//定义接口
interface Smoking {
public abstract void smoke ();
}
//定义抽象类，人类
abstract class Person {
//定义成员变量
private String name;
private int age;
//定义构造方法
public Person (){}
public Person (String name,int age) {
this.name = name;
this.age = age;
}
//初始化
public void setName(String name) {
this.name = name;
}
public String getName(String name) {
return name;
}
public void setAge(int age) {
this.age = age;
}
public int getAge(int age) {
return age;
}
//成员方法
public abstract void eat();
public void sleep() {
System.out.println("累了就睡觉");
}
}
//定义老师类
class Teacher extends Person {
public Teacher (){}
public Teacher (String name,int age) {
super(name,age);
}
public void eat(){
System.out.println("吃素");
}
}
//定义学生类
class Student extends Person {
public Student (){}
public Student(String name,int age) {
super(name,age);
}
public void eat(){
System.out.println("吃荤");
}
}
//定义抽烟的学生和老师
class SmokeStudent extends Student implements Smoking {
public SmokeStudent(){}
public SmokeStudent(String name,int age) {
super(name,age);
}
public void smoke (){
System.out.println("抽烟的学生");
}
}
class SmokeTeacher extends Teacher implements Smoking {
public SmokeTeacher(){}
public SmokeTeacher(String name,int age) {
super(name,age);
}
public void smoke (){
System.out.println("抽烟的老师");
}
}
//测试类
class InterfaceTest {
public static void main(String[] args) {
//建立抽烟学生的对象,不用多态，用具体类
SmokeStudent ss = new SmokeStudent("魏娜",27);
System.out.println(ss.getName()+"----------"+ss.getAge());
ss.sleep();
ss.eat();
ss.smoke();
}
}
