Car.java
public?class?Car?{
public?String?num;
public?float?price;
public?Car(String?num,float?price){
this.num?=?num;
this.price=price;
System.out.println("車牌號(hào)為："+num+",價(jià)格為："+price);
}
}
測(cè)試類:
public?class?CarTest?{
public?static?void?main(String[]?args)?{
Car?car?=?new?Car("京P34E68",?100000.23f);
}
}
輸出為：車牌號(hào)為：京P34E68,價(jià)格為：100000.23
第二題：

public?class?Student?{
private?String?num;
private?String?name;
private?int?age;
private?String?sex;
public?String?getNum()?{
return?num;
}
public?void?setNum(String?num)?{
this.num?=?num;
}
public?String?getName()?{
return?name;
}
public?void?setName(String?name)?{
this.name?=?name;
}
public?int?getAge()?{
return?age;
}
public?void?setAge(int?age)?{
this.age?=?age;
}
public?String?getSex()?{
return?sex;
}
public?void?setSex(String?sex)?{
this.sex?=?sex;
}
public?String?tell()?{
return?"Student?[num="?+?num?+?",?name="?+?name?+?",?age="?+?age+?",?sex="?+?sex?+?"]";
}
public?static?void?main(String[]?args)?{
Student?student?=?new?Student();
student.setAge(18);
student.setNum("001");
student.setName("COLD");
student.setSex("男");
System.out.println(student.tell());
}
}
輸出：Student [num=001, name=COLD, age=18, sex=男]
