本文通过一个具体的Java程序实例，展示了如何使用继承来实现不同角色（囚犯、教师和学生）的具体信息展示。通过定义基本类及其子类的方式，实现了代码复用，并且每个子类都重写了toString()方法以展示其特有的属性。

package test;
public class test {

   public static void main(String[] args) {
       prison t1= new prison("王","男",20);
       teacher t2=new teacher("张","女",40,"老师","计算机学院");
       student t3=new student("李","男",20,"001","计202");
       System.out.println(t1.toString());
       System.out.println(t2.toString());
       System.out.println(t3.toString());
       // TODO Auto-generated method stub
       //System.out.println("Hello World!");
   }

}
class prison{
   String name;
String sex;
   int age;
   public prison(String name,String sex,int age) {
       this.name=name;
       this.sex=sex;
       this.age=age;
   }
   public String toString() {
       String s="姓名"+name+"性别"+sex+"年龄"+age;
       return s;
   }

}
class teacher extends prison{
   String position;
   String department;
   public teacher(String name,String sex,int age,String position,String department) {
       super(name,sex,age);
       this.position=position;
       this.department=department;
   }
   public String toString() {
       return super.toString()+"职位"+position+"部门"+department;
   }
}
class student extends prison{
   String number;
   String Class;
   public student(String name,String sex,int age,String number,String Class) {
       super(name,sex,age);
       this.number=number;
       this.Class=Class;
   }
   public String toString() {
       return super.toString()+"学号"+number+"班级"+Class;
   }
}
