class Student implements Achievement

//调用父类中的构造方法
}
public void setScore(int c,int m,int e)

Math=m;
English=e;
}
public float average()

return (Chinese+Math+English)/3;
}
}
class test42 { //主类
public static void main(String[] args) {
// TODO Auto-generated method stub
Student s1=new Student("张三",16);
//调用s1的introduce方法
s1.setScore(80, 90, 80);
System.out.println(s1.average());
}
}
怎么调用 //调用s1的introduce方法和 //调用父类中的构造方法
