下面一段程序哪里错了啊，请高手指点！～

Question

class FamilyMember
{
  static private String surname="李";
  private String givenname;
  static String getSurname()
    {
      return surname;//1处：拼写错误
    }
  static void changeSurname(String surname)
    {
      //2处：2句的作用一样，况且静态方法里不能用this
      FamilyMember.surname=surname;
    }
  FamilyMember(String givenname)
    {
      this.givenname=givenname;
    }
  //3处返回值类型错误，应该是无类型的void
  void Member()
    {
      givenname="小刚";
    }
  public String whatIsYourName()
    {
      return(surname+givenname);
    }
}

Answer 1

//public class ClassMethod没有申明类在的包时不能用public
class ClassMethod   
{
public static void main(String args[])
  {
    System.out.println(FamilyMember.getSurname());
    FamilyMember a=new FamilyMember("老三");
    System.out.println(a.getSurname());
    System.out.println(a.whatIsYourName());
    FamilyMember.changeSurname("刘");
    System.out.println(a.whatIsYourName());
  }
}
class FamilyMember
{
    static private String surname="李";
    private String givenname;
    static String getSurname()
      {
         // return  surnname;变量不同
         return  surname;
      }
    static void changeSurname(String surname)
      {
       // this.surname=surname; 不能用this
        FamilyMember.surname=surname;
      }
    FamilyMember(String givenname)
      {
        this.givenname=givenname;
      }
    //Family Member()没有定义这个类型
    void Member()
      {
        givenname="小刚";
      }
    public String whatIsYourName()
      {
        return(surname+givenname);
      }
}
