java 类与对象 3---super关键字

1.调用父类中被覆盖的方法；

父类Person:

public class Person{    publci String name;    publci int age;    public void getInfo(){        System.out.println("姓名为："+name);        System.out.println("年龄为："+age);    }}

子类Worker:

public class Worker extends Person{    String company;    public void getInfo(){        //重写父类的getInfo()方法        super.getInfo();        System.out.println("公司为："+company);    }    public static void main(String[] args){                Worker worker = new Worker();        worker.name = "小屋";        worker.age = 18;        worker.company = "天马集团";        worker。getInfo();    }}

2.使用super关键字调用父类的构造方法；

不继承父类的构造方法

public class Animal{    String skin;    public Animal(String str){        skin = str;    }}

public class Bird extends Animal{    public Bird(){        super("毛毛");    }}
