Neka bude da sam ja nejasno objasnio problem:

Ovo je cela klasa Student:

Code:
import java.io.*;
public class Student {

    BufferedReader unos = new BufferedReader ( new InputStreamReader (System.in) );
    String odgovor = "";

    private String ime;
    private String programStudija;
    private int godina;
    private int idBroj;
    private String imeMentora;
    private double brojBodova;
    private boolean jeUpisan;

    // GET metode
    public String getIme()   { return ime; }
    public String programStudija() { return programStudija; }
    public int godina() { return godina; }
    public int idBroj() { return idBroj; }
    public String getImeMentora() { return imeMentora; }
    public double getBrojBodova() { return brojBodova; }
    public boolean jeliUpisan() { return jeUpisan; }

   // EDIT METODA

/* Editiraj studentove podatke
*/
public void edit(ConsoleReader input)
{
    System.out.print("ID (" + idBroj +") " );
    String odgovor = input.readLine();

    if (! odgovor.equals("")) {
            idBroj = odgovor;
            System.out.print("Ime (" + ime + ") ");
            odgovor = input.readLine();  }

    if (! odgovor.equals("")) {
            ime = odgovor;
            System.out.print("Program studija (" + programStudija + ") ");
            odgovor = input.readLine();
    if (! odgovor.equals(""))

    if (odgovor.equals("Elektronika") || odgovor.equals("Arhitektura") ) {
            programStudija = odgovor;
        else  {   System.out.println("Nepoznat program studija.");   }

        System.out.print("Godina (" + godina + ") ");
        odgovor = input.readLine();

    if (! odgovor.equals(""))  {  godina = Integer.parseInt(odgovor);  }

}


    // SET metode
    public void povecajGodinu() { godina++; }
    public void setIme(String x) { ime=x; }
    public void setProgramStudija(String x) { programStudija = x; }
    public void setIdBroj(int x) { idBroj = x; }
    public void setImeMentora(String x) { imeMentora = x; }
    public void setBrojBodova(double x) { brojBodova = x; }
    public void dodajBod() { brojBodova += 0.5; }
    public void upisi() { jeUpisan = true; }
    public void ispisi() { jeUpisan = false; }

    // KONSTRUKTORI
    public Student(String i, String p, int g, int id)
    {   idBroj = id;
         ime = i;
         godina = g;
         programStudija = p;
         imeMentora = "";
         brojBodova=0;
         jeUpisan = false;
     }
     public Student()
     {  idBroj=0;
          ime = "";
          godina = 0;
          programStudija = "";
          imeMentora = "";
         brojBodova=0;
         jeUpisan = false;

     }
     public Student(String i, String p, int id)
     {  idBroj = id;
          ime = i;
          programStudija = p;
          godina = 1;
          imeMentora = "";
         brojBodova=0;
         jeUpisan = false;
     }
     public Student(String i)
     {  idBroj = 0;
         ime = i;
         godina = 0;
         programStudija = "";
         imeMentora = "";
         brojBodova=0;
         jeUpisan = false;

     }

     // STAMPANJE
     public void prikaz() {
         System.out.println("Ime:\t" + ime +
                           "\nProgramStudija:\t" + programStudija +
                           "\nGodina:\t" + godina +
                           "\nidBroj:\t" + idBroj +
                           "\nImeMentora:\t" + imeMentora +
                           "\nBrojBodova:\t" + brojBodova +
                           "\nStatus:\t" + jeUpisan);
     }
}

Ovo je ConsoleReader

Code:
package PhoneApp;

import java.io.BufferedReader;
import java.io.InputStreamReader;
import PhoneApp.Data.*;

/**
* This class provides the ability to read input from
* a console. Users must enter commands line-by-line,
* as the input is only triggered by hitting enter.
*
* @version $Date: 2001/06/25 $
* @author  Steve Franklin
* @since   jdk 1.3.1
*/

class ConsoleReader {

/**
  * Default constructor has no behavior.
  */
  public ConsoleReader() {

  }

/**
  * Send a prompt to the users, typically indicating the
  * type of information that the software is expecting.
  */
  public void sendPrompt(String prompt) {
    sendText(prompt + "\n");
  }

/**
  * Send text to the user, and flush the output.
  */
  public void sendText(String text) {
    System.out.print(text);
    System.out.flush();
  }

/**
  * Retrieve input from the user after providing a field-level
  * prompt.
  */
  public String getInput(String prompt) {
    System.out.print(prompt + ": ");
    System.out.flush();
    String userEntry = readInput();
    return userEntry;
  }

  /**
   * Read a number from the console
   */
  public int getUserNumber(String title, String prompt) {
    if ( title.length() > 0 ) {
      sendPrompt(title);
    }
    String optionText = getInput(prompt);
    int option = -1;
    try {
      option = Integer.parseInt(optionText);
    } catch (Exception e) {
      System.out.println("Unrecognized option.");
    }
    return option;
  }

/**
  * Read input from the console using the BufferedReader. Trigger
  * input based on the user pressing enter. This function reads one
  * line at a time.
  */
  private String readInput() {
    BufferedReader consoleInput = new BufferedReader(new InputStreamReader(System.in));
    String userEntry = "";
    try { userEntry=consoleInput.readLine(); } catch (java.io.IOException e) { userEntry = ""; }
    return userEntry;
  }

}

I osnovni program recimo:

Code:
import java.io.*;
class probaStudent {
    public static void main(String[] args) {

       BufferedReader unos = new BufferedReader (new InputStreamReader(System.in));

       Student prvi = new Student();

       prvi.prikaz();

       System.out.println("Unesite ime studenta: ");
       try { prvi.setIme(unos.readLine()); } catch (IOException io) {}

       System.out.println("Unesite program studija: ");
       try {  prvi.setProgramStudija(unos.readLine()); } catch (IOException io) {}

       System.out.println("Unesite idBroj: ");
       try {  prvi.setIdBroj(Integer.parseInt(unos.readLine())); } catch (IOException io) {}

       prvi.prikaz();

       prvi.setIme("miljan");

       prvi.prikaz();

       prvi.povecajGodinu();

       prvi.prikaz();

       System.out.println();
       System.out.println("Editiraj podatke studenta.");
       st.edit(in);
       System.out.println();
       System.out.println("Student podaci:");
       st.prikaz();
   }
}

I u EDIT metodi nije mi jasno kako da umesto ConsoleReader klase napisem preko BufferedReader, sta treba menjati?
