大家帮忙看下，为什么会编译错误？


import java.util.HashSet;
class Student{
int num;
String name;
double scores[];  //三门课程成绩
double aver;      //平均成绩 public Student(){
this.scores=new double[3];
}
public Student(int num,String name,double score1,double score2,double score3){
this ();
this.setNumber(num);
this.setName(name);
this.setScores(double score1,double score2,double score3);//这里为什么编译错误？
this.aver=(this.scores[0]+this.scores[1]+this.scores[2])/3;
}

public void setNumber(int num){
this.num=num;
}
public void setName(String name){
this.name=name;
}

}
