给定如下代码，编译时会出现错误

class{
}
class Chlid extends Parent{
public static void main(String args[]){
Parent p1=new Chlid();
Parent p2=new Parent();
Chlid c1=new Chlid();
Chlid c2=new Chlid();
}
}

class Parent{
}
public class Chlid extends Parent{
public static void main(String args[]){
Parent p1=new Chlid();
Parent p2=new Parent();
Chlid c1=new Chlid();
Chlid c2=new Chlid();
}
}

最上面那个class{}不清楚是你忘记写类名还是啥，反正我这样写编译运行都没问题
