Automated Teller Machine (ATM) implementation in Java

Question

I am trying to code ATM code with bank account. I used arraylist and when the user creating his account I added his account to the list. I used switch-case and I couldn't use methods.

If someone can fix this it would be perfect I am really trying to figure out how to do this. in case 1 you can see I added the new bankaccount to the list, I made an ATM c object on case 1 and I am trying to make is accesible in case 2. ty guys

Main:

    public static void main(String[] args) {
    Scanner in = new Scanner(System.in);
    ArrayList<BankAccount> accounts = new ArrayList<BankAccount> ();
    boolean exitRequested = false;
    while (!exitRequested) {
        System.out.println("Please chose an option:" +"\n" +
                "1.New account" + "\n" +
                "2.Exist account" + "\n" +
                "3.Exit");
        int options = Integer.parseInt(in.nextLine());
        switch (options) {
            case 1:
                System.out.println("Welcome to our bank!" + "\n" + "Please answer few questions in order to complete registation.");
                System.out.println("First name: ");
                String fn = in.nextLine();
                System.out.println("Last name: ");
                String ln = in.nextLine();
                System.out.println("Welcome " + fn + "!");
                accounts.add(new BankAccount(1,fn,ln));
                System.out.println(accounts.get(0).toString());
                ATM c = new ATM(accounts.get(0));
                break;
            case 2:
                System.out.println("Please enter your bankaccount id: ");
                int customerId = Integer.parseInt(in.nextLine());
                if(customerId == accounts.get(0).getId()) {
                System.out.println("What would you like to do?" +"\n" +
                        "1. Withdraw" + "\n" +
                        "2. Deposit" + "\n" +
                        "3. info");
                String chose = in.nextLine();
                if(chose.equals("1")) {
                    System.out.println("How much would you like to withdraw?");
                    int withdrawValue = Integer.parseInt(in.nextLine());
                    c.withdraw(withdrawValue); // here is the problem
                    System.out.println("You've withraw " +withdrawValue + "from your account!");
                } else if(chose.equals("2")){
                    System.out.println("How much would you like to deposit?");
                    int depositValue = Integer.parseInt(in.nextLine());
                    c.deposit(depositValue); // also here ..
                    System.out.println("You've deposit " +depositValue +"to your account succesfuly!");
                } else if(chose.equals("3")) {
                    System.out.println(c.toString()); // ...
                }

            } else {
                    System.out.println("Invaild id");
                }
                break;

            case 3:
                exitRequested = true;
                break;
        }
    }
}

ATM:

public class ATM extends BankAccount{

    private BankAccount bank;

public ATM(BankAccount bank){

}

public ATM() {

}

public void withdraw(int value){
    if(getBalance() < value ){
        System.out.println("You dont have enough funds.");

    } else {
        setBalance(getBalance() - value);
    }
}

public void deposit(int value){
    setBalance(getBalance() + value);
}

BankAccount:

public class BankAccount {

private int id;
private String fName;
private String lName;
private int balance;


public BankAccount(int id, String fName, String lName){
    this.id = id;
    this.fName = fName + "";
    this.lName = lName + "";
    this.balance = 0;
}

public BankAccount() {

}

public int getId(){
    return this.id;
}

public void setId(int value){
    this.id = value;
}

public String getFirstName(){
    return this.fName;
}

public void setFirstName(String value){
    this.fName = value;
}

public String getLastName(){
    return this.lName;
}

public void setLastName(String value){
    this.lName = value;
}

public int getBalance(){
    return this.balance;
}

public void setBalance(int value){
    this.balance = value;
}


public String toString(){
    return "Name: " + getFirstName() +"\n" +
           "Last name: " + getLastName() + "\n" +
            "ID: " + getId() + "\n" +
