package cn.itcast.heima;

class Sutdent{
private String name;
private int age;
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 class IntroBean {
public static void main(String[] args)throws Exception {
Sutdent stu=new Sutdent();
BeanUtils.setProperty(stu,"age",2);//提示的错误在这 BeanUtils.getProperty(stu, "age");
}
}
大家帮忙看看，这段代码怎么运行不对啊？工具包都倒好了，运行时会出现这种错误
