给个参考例子：

public class Demo {
    public static void main(String[] args) {
        Person p = new Person( "小明", 12) ;
        Student s = new Student ("小红",  18, 78.5) ;
    }
}
class Person{
    String name;
    int age;
    public Person(String name, int age) {
        this.name= name;
        this.age =age;
    }
    
}
class Student extends Person{
    double score;
    public Student(String name, int age, double score) {
        super(name, age);
        this.score = score;
    }
}
