第五章 接口与抽象类的应用-v1.ppt

1、第5章抽象类和接口应用程序、抽象类应用程序、abstract class person private string name；专用int agePublic person (string name，intage)this . name=name；This.age=agepublic string get name()return this . name；public intge tage()returnthis . age；public abstract String get content()；public void say()system . out . print ln(this .

2、get content()；class student extends person private float score；Public student (string name，intage，float score) super (name，age)；This.score=scorePublic String getContent() return学生说：名字：super.getName()年龄： super.getAge()成绩3360 this.score，classPublic worker (string name，intage，float salary) super (name，

3、age)；This.salary=salaryPublic String getContent() return工人表示，姓名：super.getName()年龄： super.getAge()薪金3360 this.salary，public clar aryper 1 . say()；per 2 . say()；接口应用程序，界面Usb public void start()；界面Usb public void start()；public void stop()；class computer public static void plugin(USB USB)USB . start()；
