[RESOLVED] arrayList problem

hi all,
in my code, only one class object which is c1 displays twice but why not c too?
please help me, i don't understand why is it so.... please anyone :cry:

Code:

---

public static void main(String args[])throws IOException
        {
                Customer c =new Customer();
                Customer c1 =new Customer();
                                       
                String cname="";
                String uname="";
                int pn=0;
                double bal=0.0;
                int anum=1;
               
                InputStreamReader isr = new InputStreamReader( System.in );
        BufferedReader br = new BufferedReader( isr );
        ArrayList<Customer> arrayList = new ArrayList<Customer>();
       
          System.out.println( "Enter your name : " );
      cname = br.readLine( );
          c.setName(cname);
          cname=c.getName();
          System.out.println( "Enter your user name : " );
      uname = br.readLine( );
          c.setUserName(uname);
          uname=c.getUserName();
          System.out.println("Enter your pincode :");
                pn = Integer.parseInt(br.readLine( ));
          c.setPinCode(pn);
          pn=c.getPinCode();
          System.out.println("Enter your balance :");
                bal = Double.parseDouble(br.readLine( ));
          c.setBalance(bal);
          bal=c.getBalance();
         
          System.out.println( "Enter your name : " );
      cname = br.readLine( );
          c1.setName(cname);
          cname=c1.getName();
          System.out.println( "Enter your user name : " );
      uname = br.readLine( );
          c1.setUserName(uname);
          uname=c1.getUserName();
          System.out.println("Enter your pincode :");
                pn = Integer.parseInt(br.readLine( ));
          c1.setPinCode(pn);
          pn=c1.getPinCode();
          System.out.println("Enter your balance :");
                bal = Double.parseDouble(br.readLine( ));
          c1.setBalance(bal);
          bal=c1.getBalance();
       
                c = new Customer(anum , cname , pn , uname , bal);
                c1 = new Customer(anum , cname , pn , uname , bal);               
                arrayList.add(c);
                arrayList.add(c1);
                System.out.println("Account Successfully Created -- The Account Number Assigned Is : " + anum);
                               
        System.out.println("size of list"+arrayList.size());       
       
                //*********************display************************
                        for(int i=0; i<arrayList.size(); i++)
                        {
                        System.out.println(arrayList.get(i).toString());
                        }
       
               
        }

thanks...

solved now..

You didn't posted the solution !

Here's a bit cleaned version of your code:

Code:

---

public class Company
{
        public static void main(String args[])throws IOException
        {
               
                //Declare all variables
                String cname="";
                String uname="";

                int pn=0;
                double bal=0.0;
               
                //Create the reader and arraylist
                BufferedReader br = new BufferedReader( new InputStreamReader( System.in ) );
                ArrayList<Customer> arrayList = new ArrayList<Customer>();
               
                //Get the number of accounts that needs to be created
                System.out.println("Enter the number of accounts you want to create:");
                int n = Integer.parseInt(br.readLine( ));
               
                //Create the accounts one by one
                for(int i=1;i<=n;i++)
                {
                        System.out.println("\n\nEnter new account details\n---------------");
                       
                        System.out.println( "\nEnter your name : " );
                        cname = br.readLine( );

                        System.out.println( "\nEnter your user name : " );
                        uname = br.readLine( );

                        System.out.println("\nEnter your pincode :");
                        pn = Integer.parseInt(br.readLine( ));

                        System.out.println("\nEnter your balance :");
                        bal = Double.parseDouble(br.readLine( ));
                       
                        //Create the customer object with the input values and add it to arraylist
                        arrayList.add(new Customer(i , cname , pn , uname , bal));
                       
                        System.out.println("Account Successfully Created -- The Account Number Assigned Is : " + i);
                       
                }
               
                                                               
                System.out.println("Number of accounts:"+arrayList.size());       
               
                //*********************display************************
                for(int i=0; i<arrayList.size(); i++)
                {
                        System.out.println(arrayList.get(i).toString());        //assuming you have overrided the toString() function
                }
                       
        }
}

I didn't tested it. Hope it will work. :wave:

thanks :)

this is what i did yesterday.

Code:

---

import java.util.*;
import java.io.*;
public class Student{
private String name;
public static int num=0;
public void setName(String n)
        {
                name=n;
        }
        String getName()
        {
                return name;
        }
        public Student(String n)
        {
                name=n;
        }
        public Student()
        {}
        public String toString()
        {
      return (name);
        }

  public static void main(String[] args)throws IOException {
  String cname;
  Student c=new Student();
  Student c1=new Student();
  InputStreamReader isr = new InputStreamReader( System.in );
  BufferedReader br = new BufferedReader( isr );
 
   
        System.out.println( "Enter your name : " );
      cname = br.readLine( );
          c.setName(cname);
          cname=c.getName();
          Student i1=new Student(cname);
         
          System.out.println( "Enter your name : " );
      cname = br.readLine( );
          c1.setName(cname);
          cname=c1.getName();
          Student i2=new Student(cname);
  ArrayList<Student> arl=new ArrayList<Student>();
 
  arl.add(i1);
  arl.add(i2);
 
  System.out.println("The content of arraylist is: " + arl);
 
 
  }
}
