这组代码有问题，可以帮助改一下吗？



public static void main(String[] args) {
// TODO Auto-generated method stub

private int Number;

public Course() {
}
public Course(int q,String w,double e)
{
Number = q;
NameCourse = w;
Score = e;
}
public int getnubmer();
{
return Nubmer;
}
public String getname();

return NameCourse;
}
public double getscore();
{
return Score;
}
public double classtime();
{
double ClassTime = Score*16;
return ClassTime;
}
}
