Can You Give sample coding for my view....or you can
check in your program whether the following kinds of
char or occur..
har a = '\c';
char b = '\r'; 
char c = '\"'; 
char d = '\b'; 
char e = '\''; 
here is my code import java.io.*;
import java.util.*;
public class PassengerSystem{
private Map arrPassenger = new HashMap();
public Map getArrPassenger(){
return arrPassenger;
//Load the text file records.
public void loadFile()throws IOException{
boolean a=true;
     //File f = new File("a:\\reservations.txt");
File f = new File("C:\\windows\desktop\desktop\150906\reservations.txt");
BufferedReader BR = new BufferedReader(new FileReader (f));
boolean moredata = true;
Passenger newapplication;
while(moredata){
newapplication = new Passenger();
moredata = newapplication.readfile(BR);
if (moredata){
getArrPassenger().put(newapplication.getName(),newapplication);
BR.close();
//Save the records to the text file
public void save() throws IOException{
PrintWriter passengerFile = new PrintWriter(new FileWriter("a:\\reservations.txt"));
Passenger aPassenger = new Passenger();
Iterator a = getArrPassenger().values().iterator();
while(a.hasNext()){
aPassenger=(Passenger)a.next();
passengerFile.println(aPassenger.getSeatNo());
passengerFile.println(aPassenger.getName());
passengerFile.println(aPassenger.getAge());
passengerFile.println(aPassenger.getGender());
passengerFile.close();
thanks in advance.
