设计一个限制子类的访问的抽象类实例，要求在控制台输出如下结果

 

 1 public class test {
 2 
 3 public static void main(string[] args) {
 4 teacher t1=new teacher(50,"刘三","教师");
 5 worker t2=new worker(30,"赵四","工人");
 6 t1.talk();
 7 t2.talk();
 8 
 9 }
10 
11 }
12 abstract class person{
13 private string name;
14 private int age;
15 
16 public person(int age,string name){
17 this.age=age;
18 this.name=name;
19 }
20 public string getname() {
21 return name;
22 }
23 public int getage() {
24 return age;
25 }
26 }
27 class teacher extends person{
28 string job="教师";
29 public teacher(int age,string name,string job){
30 super(age,name);
31 this.job=job;
32 }
33 public void talk() {
34 system.out.println("教师->姓名:"+getname()+"，年龄，"+getage()+"职业:"+job);
35 }
36 }
37 class worker extends person{
38 string job="工人";
39 public worker(int age,string name,string job){
40 super(age,name);
41 this.job=job;
42 }
43 public void talk() {
44 system.out.println("工人->姓名:"+getname()+"，年龄，"+getage()+"职业:"+job);
45 }
46 }
