Reading a txt file into an ArrayList help??

[Brendon Randall]

Hi all im new here and pretty new to java to. I am just working through examples and trying things out for my self.

What i wanted to do was read a text file that has records in them seperated by a newline and pass them into an ArrayList.

So far i have created an Accounts class that looks like this

 public class Accounts {

    private String accName;
    private String accAdd;
    private String accBal;

    public String getAccAdd() {
        return accAdd;
    }

    public void setAccAdd(String accAdd) {
        this.accAdd = accAdd;
    }

    public String getAccBal() {
        return accBal;
    }

    public void setAccBal(String accBal) {
        this.accBal = accBal;
    }

    public String getAccName() {
        return accName;
    }

    public void setAccName(String accName) {
        this.accName = accName;
    }

}   

After that i have created a class called ReadFile that looks like this

 package tests;

import java.io.FileReader;
import java.io.BufferedReader;
import java.io.IOException;

public class ReadFile {

    public ReadFile() throws IOException {

        FileReader reader = new FileReader("accounts.txt");
        BufferedReader buffReader = new BufferedReader(reader);

        String line;
        line = buffReader.readLine();

        while (line != null) {
            Accounts newAccounts = new Accounts();
            newAccounts.setAccName(line);
            line = buffReader.readLine();
            newAccounts.setAccAdd(line);
            line = buffReader.readLine();
            newAccounts.setAccBal(line);
            line = buffReader.readLine();
            line = buffReader.readLine();

        }


    }
}
   

so what i wanted to know is how can i pass what i have read from the txt file into an ArrayList as Objects?? can any one help me?

My understanding is that i would create an arraylist like

  ArrayList<Accounts> accounts = new ArrayList<Accounts>  

???

Yes, you would do something like this (I am assuming your loop is working, if not message again):

//declare list of accounts
ArrayList<Accounts> accounts = new ArrayList<Accounts>();
   
 while (line != null) {  
             Accounts newAccounts = new Accounts();  
             newAccounts.setAccName(line);  
             line = buffReader.readLine();  
             newAccounts.setAccAdd(line);  
             line = buffReader.readLine();  
             newAccounts.setAccBal(line);  
             line = buffReader.readLine();  
             line = buffReader.readLine();  
             
             accounts.add(newAccounts);//add this account to list
 }  
 //you can now display account list elements
 for (Accounts account : accounts)
 {
               System.out.println(account.getAccName());
 }
   

BTW, you should name your class as Account instead of Accounts, classes generally represent single entity, although you can have n instances (objects).
