java类——从子类调用父类方法：

/**
 * Created by xabcd on 2019/2/15.
 */


    class Person8
    {
        String name;
        int age;
        public String talk(){
            return "我是："+this.name+"，今年："+this.age+"岁";
        }
    }
    class Studen extends Person8
    {
        String school;
        public Studen(String name,int age,String school)
        {
            //分别为属性赋值
            this.name = name;
            this.age = age;
            this.school = school;
        }
        //此处覆写Person8中的talk（）方法
        public String talk()
        {
            return super.talk()+"我在"+this.school + "上学";
        }
    }

/**
 * Created by xabcd on 2019/2/15.
 */
public class TestPerson8
    {
        public static void main(String args[]){
        Studen ss = new Studen("张三",25,"北京");
            //此时调用的时子类中的talk（）方法
        System.out.println(ss.talk());
        System.out.println(ss.name);
        System.out.println(ss.age);
        System.out.println(ss.school);
    }
}
