public class Student
{
    public int Chn;
    public int Mat;
    public int Eng;
    public int avr=(Chn+Mat+Eng)/3;
    public int sum=Chn+Mat+Eng;


    public String ToStudent(){  

         return ("the average score is"+avr+"the sum score is"+sum);
    }
}

public class TestStudent
  {
    public static void main(String[] args)
    {
        Student KG=new Student();
        Student KB=new Student();

        KG.Chn=90;
        KG.Mat=85;
        KG.Eng=83;
        KB.Chn=73;
        KB.Mat=80;
        KB.Eng=82;

        System.out.println("KG:"+KG);
        System.out.println("KB:"+KB);
        }
}

结果如下：
KG:Student@c17164
KB:Student@1fb8ee3
本人意愿是输出KG和KB平均分和总分

按照你的方法修改了，可是出来结果都是0

哪里有？怎么改？
