用java编写的简单的成绩管理系统。对于初学者很有帮助

public class student2 implements scholarship
{int no;
double grade1;
double Scredits;
double Hcredits;
public student2(int no,double grade1,double Scredits,double Hcredits)
{this.no=no;
this.grade1=grade1;
this.Scredits=Scredits;
this.Hcredits=Hcredits;;
}
public student2(student2 s2)
{this(s2.no,s2.grade1,s2.Scredits,s2.Hcredits);
}
public double credits1()
{switch(credits)
{case(60<=grades1<70):
{credits1=2.5;
break;
}
{case(70<=grades1<80):
{credits1=3;
break;
}
{case(80<=grades1<90):
{credits1=3.5;
break;
}
{case(60<=grades1<70):
{credits1=4;
break;
}
}
}


public String toString()
{return this.AVGcredits();
}
public void print()
{System.out.print();
}
	public static void main (String args[])
{student2 s2=new student2(20063900,80,3,4);
s2.print();
System.out.println(s2);
}
