Question

public abstract class  person
  {    
public abstract void show();
public abstract void println();}public class student extends person
   {   int studentno;
       String studentname,String s;
    student(int studentno,String studentname,String s)
   { while(studentname!="#")
       {  System.out.println("input");
           BufferedReader in=new BuffereReader(new InputStreamReader(System.in));
              studentname=in.readLine();
           studentno=Integer.parseInt(in.readLine());
             System.out.println(studentno,studentname);
            System.out.println("input the job");
               s=in.readLine();
               job[]=new char[20];
             for(int i=0;i<s.length();i++)
                job[i]=s.char(i);
             System.out.println(job[i]);
          }
    }
     public static void show
         {   
              int ;
            student(int studentno,String studentname,String s); 
           
           public void show            { 
               BufferedReader in=new BuffereReader(new InputStreamReader(System.in));
         
               =Integer.parseInt(in.readLine());
            
       }     public static void println
          {  System.out.println();
    }}
 这段程序的抽象类不知道应该怎么写，感觉很乱，错误很多。请详细指点一下。      
    

Answer 1

子类方法的定义应该和父类一样啊
也应该是public abstract void show(); 
public abstract void println(); 而不应该是public static void println 

Answer 2

子类方法的定义应该和父类一样啊 
应该是public void show(); 
public void println(); 而不应该是public static void println 

Answer 3

public  void println(){ 
         System.out.println(); 
    }
