Im trying to make a small CRUD using a ArrayList in Java using the console, when i register a new Account it overwrite the last object and always stay with one object in ArrayList, the List doesn't grow up!
I want to understand my mistake!
My logic:
- I create a new object of Account in the Main Class;
- Get the information using the Scanner Class;
- Send object to method "registerAccount", that will add on an ArrayList;
- When i print using the getAll() method it display the last object that i register.
My Code:
This class get the information and send to Account class to make the regsiter!
public class Main {
public static void main(String[] args) {
// TODO Auto-generated method stub
//Class statements
Scanner scan = new Scanner(System.in);
Account account = new Account();
//Variables statements
int option = 0;
System.out.println("---Welcome to Dream Bank-----\n");
while(option != 4){
System.out.println("1 - Access your account");
System.out.println("2 - Create an account");
System.out.println("3 - List all accounts");
System.out.println("4 - Exit");
option = scan.nextInt();
if (option == 1){
System.out.println("Comming soon");
} else if (option == 2){
System.out.print("Number account: ");
account.number = scan.nextInt();
System.out.print("Name: ");
account.name = scan.next();
System.out.print("Balance: ");
account.balance = scan.nextDouble();
account.special = false;
account.bound = 1000;
account.registerAccount(account);
} else if (option == 3){
account.getAll();
}
}
scan.close();
}
}
This class contains the method to resgiter and display on console.
public class Account {
int number;
String name;
double balance;
boolean special;
double bound;
List<Account> accounts = new ArrayList<Account>();
public void registerAccount(Account account){
accounts.add(account);
}
public void getAll(){
for(int i=0; i<accounts.size(); i++){
System.out.println(accounts.get(i).name);
}
}
}
