通过super调用父类属性和方法

class Person{    String name;    int age;    //父类的构造方法    public Person() {    }    public String talk() {        return "i am:"+this.name+", i am "+ this.age +"years old";    }}class Student extends Person{    String school;    //子类的构造方法    public Student(String name, int age, String school) {    //在这里用super调用父类中的属性        super.name=name;        super.age=age;        //调用父类中的talk()方法        System.out.print(super.talk());        //调用本类中的school属性        this.school=school;    }}public class example12_12 {    public static void main(String[] args) {        Student s= new Student("Jack",30,"HAUT");        System.out.println(", I am from :"+s.school);    }}
