how come i can't call my search method from my main method?

[hrin kuek]

hi all,

was wondering why i keep gettin a compiling error when i try to call my search method from my main method... ( see last few lines of code )

import java.io.*;
import java.util.*;
import java.lang.*;
 

class searchBooking
{
int bookingId;
String custName;
private Reservation aReservation;
Vector v;

public Reservation searchcustName(String custName, Vector v)
{
    for( int i = 0; i < v.size(); i++) 
    {
        Reservation aReservation = ((Reservation) v.elementAt(i));
        if ((aReservation.getcustName().equals(custName))) return (aReservation);
        
        }
        return null;
        
 

}

 
}
  

 import java.io.*;
import java.util.*;
import java.lang.*;
 
class addReservation1
{
static BufferedReader stdin = new BufferedReader (new InputStreamReader(System.in));

//Main Method
public static void main (String[]args)throws IOException
{
String custName, comments;
int covers, date, startTime, endTime;
int count = 0;
Vector oneReservation=null;
boolean smoking=true;

oneReservation=new Vector();

//User can only add one reservation at a time
do
{

System.out.println("Please enter customer's name:");
System.out.flush();
custName = stdin.readLine();

System.out.println("Please enter number of covers:");
System.out.flush();
covers = Integer.parseInt(stdin.readLine());

System.out.println("Please enter smoking or non-smoking (S/N):");
System.out.flush();
String s= stdin.readLine();
String upperS=s.toUpperCase();
if (upperS.charAt(0)=='S')
smoking = true;
else 
{if (upperS.charAt(0)=='N')
smoking = false; 
}
System.out.println("Please enter date:");
System.out.flush();
date = Integer.parseInt(stdin.readLine());

System.out.println("Please enter start time:");
System.out.flush();
startTime = Integer.parseInt(stdin.readLine());

System.out.println("Please enter end time:");
System.out.flush();
endTime = Integer.parseInt(stdin.readLine());

System.out.println("Please enter comments, if any:");
System.out.flush();
comments = stdin.readLine();

//Instantiate new object
oneReservation.addElement(new Reservation(custName,covers,smoking,date,startTime,endTime,comments));

count++;

System.out.println("Vector contains "+oneReservation.size()+" objects");

for (int i=0; i<oneReservation.size();i++)
{
Reservation r1=(Reservation)oneReservation.elementAt(i);
System.out.println(r1.getcustName()+" "+r1.getCovers() +" "+ r1.getSmoking()+" "+ r1.getDate()+" "+r1.getstartTime()+" "+r1.getendTime()+" "+r1.getComments());
}

 
} 
while (count<2);


searchcustName("dan", oneReservation);

 


 
}
}

What error do you get?

[hrin kuek]

cannot resolve symbol method searchcustName [java.lang.string,java.util.vector]

[K Riaz]

You must create an instance of the object before you can invoke methods on it.

oh ok thx! managed to fix it.

but now i m havin another problem.. I need to display ALL records that have the same name. but when i put in a for loop like this, it jus keeps repeating the first record many times. how do i code such tt it returns all the records tt have the same custName?

  
for (int i=0; i<oneReservation.size();i++)
{
searchBooking sb = new searchBooking();
Reservation res = sb.searchcustName("dan", oneReservation);
System.out.println(res.getcustName()+" "+res.getCovers() +" "+ res.getSmoking()+" "+ res.getDate()+" "+res.getstartTime()+" "+res.getendTime()+" "+res.getComments());
}

[K Riaz]

Use an iterator, which is inherited by the Vector class from AbstractList.

Iterator i = oneReservation.iterator();
 
while (i.hasNext())
{
Object o = i.next();
//process o
 
}

Hi,

I think the class level variable custName in SearchBooking is conflicting with the method variable custName. Try changing the name either one of the variable.

Hope this helps.
