person p1＝new person class person出现错误

package asdw;

public class Arsd {

public static void main(String src[])
{
   Person p1=new Person(); 
        p1.name="陈华一";p1.sex="男"; p1.age=19; p1.height = 1.80f; p1.weight= 56;
        Person p2 =new Person();
        p2.name="陈一艺";p2.sex="女";p2.age=18; p2.height = 1.75f; p2.weight= 46;
        ((Arsd) p1).display();
        System.out.println("\n");
        ((Arsd) p2).display();

}
}
Class Person {
String name;
int age;
String sex;
float height;
float weight;
void display(){
System.out.println("大家好！，我的名字叫："+name);
System.out.println("我的性别是："+sex);
System.out.println("今年我："+age+"岁");
System.out.println("身高："+height+"米，体重："+weight+"公斤");
}

}

void display()
->
public void display()

p1.display();
就可以了
