Thread: PrintStream Help!

I want to create a simple console account application that allow's you to create accounts and the accounts will be save in a txt files. Code:

package main;
 
import static java.lang.System.out;
 
import java.io.File;
import java.io.FileNotFoundException;
import java.util.Scanner;
 
public class mainClass {
 
        public static void main(String[] args) throws FileNotFoundException {
                Scanner sn = new Scanner(new File("Usernames.txt"));
                Scanner s = new Scanner(System.in);
                newAccount a = new newAccount();
                int ID = 0;
 
                while(sn.hasNext()){
                        ID = ID + 1;
                        sn.nextLine();
                }
                do{
        out.print("Enter username: ");
        a.user = s.nextLine();
        out.print("Enter password: ");
        a.password = s.nextLine();
        a.ID = ID;
        a.print();
        out.println();
        out.print("Create another account?");
                }while(s.findWithinHorizon(".", 0).charAt(0) == 'y');
 
        }
 
}
 
//Method class
 
package main;
 
import java.io.FileNotFoundException;
import java.io.PrintStream;
 
public class newAccount {
 
        String user;
        String password;
        int ID;
 
        void print() throws FileNotFoundException{
 
            PrintStream u = new PrintStream("Usernames.txt");
                PrintStream p = new PrintStream("Passwords.txt");
 
 
                for(int i = 0; i < ID; i++){
                        p.println();
                        u.println();
                }
        u.println(user);
        p.println(password);
        }
}

My problem: Every time a new account is created all previous accounts will be deleted because I use: u.println(""); and p.println(""); How can I fix this problem? Thanks!

Please post the code here that you are having problems with.

Is this the problem: when adding a new record to an existing file, the old file is overwritten instead of the new record added to the end?
Look at using the file writing class's constructor with the append option.

Use the class that has the append option in the class's constructor. Set it to true.
I don't know the name of the class right now. It might be FileWriter. Look in the API doc.
