测试类：

public class TestClass \{

public static void main(String\[\] args) throws Exception \{  
Student stu = new Student();  
 // 1 通过对象.getClass()的方式获取  
Class<?> c1 = stu.getClass();  
System.out.println(c1);  
 // 2直接通过类.class的方式获取  
Class<?> c2 = Student.class;  
System.out.println(c2);  
 // 3通过Class.forname(全路径)的方式来获取  
Class<?> c3 = Class.forName("com.fanshe.test.Student");  
System.out.println(c3);  
  
  
System.out.println("--------------------------------------");  
System.out.println("获取类的全称:" + c3.getName());  
System.out.println("获取类的简称:" + c3.getSimpleName());  
System.out.println("判断是不是枚举:" + c3.isEnum());  
System.out.println("判断是不是接口:" + c3.isInterface());  
System.out.println("获取类的访问修饰符:" + c3.getModifiers());  
System.out.println("解析后的修饰符:" + Modifier.toString(c3.getModifiers()));  
System.out.println("获取父类的信息:"+c3.getSuperclass().getSimpleName());  
  
  
\}

Student类：

package com.fanshe.test;  
  
  
public final class Student extends Person \{  
private String name;  
public int age;  
protected double score;  
String sex;  
  
  
public Student() \{  
super();  
// TODO Auto-generated constructor stub  
\}  
  
  
public Student(int id, String coure, String name, int age, double score,  
String sex) \{  
super(id, coure);  
this.name = name;  
this.age = age;  
this.score = score;  
this.sex = sex;  
\}  
  
  
public String getName() \{  
return name;  
\}  
  
  
public void setName(String name) \{  
this.name = name;  
\}  
  
  
public int getAge() \{  
return age;  
\}  
  
  
public void setAge(int age) \{  
this.age = age;  
\}  
  
  
public double getScore() \{  
return score;  
\}  
  
  
public void setScore(double score) \{  
this.score = score;  
\}  
  
  
public String getSex() \{  
return sex;  
\}  
  
  
public void setSex(String sex) \{  
this.sex = sex;  
\}  
  
  
\}
