import java.io.InputStreamReader;

class Person{
private String firstName;
private String lastName;
private int phoneNumber;
private String emailAddress;
  
public Person(String fName, String lName, int phNumber, String email){
  
this.firstName = fName;
this.lastName = lName;
this.phoneNumber = phNumber;
this.emailAddress = email;
  
}
  
public String getFirstName() { return this.firstName;}
public String getLastName() { return this.lastName;}
public int getPhoneNumber() { return this.phoneNumber;}
public String getEmailAddress() {return this.emailAddress; }
  
}
class Bank{
protected int accountNumber;
protected Person accHolder;
protected int balance;
  
public void updateBalance(int balance){
this.balance = balance;
System.out.println("Balance updated to::"+balance);
}
public void addBankAccount(){
  
try{
BufferedReader reader =
new BufferedReader(new InputStreamReader(System.in));

System.out.println("Enter Account number:");
int accountNumber;
boolean isValid = true;
do{
accountNumber = Integer.parseInt(reader.readLine());
if(accountNumber < 0) {
System.out.println("Bad Account Number, Enter Again:");
isValid = false;
}
  
}while(!isValid);
  
this.accountNumber = accountNumber;
System.out.println("Enter firstName:");
String fName = reader.readLine();
  
System.out.println("Enter lastName:");
String lName = reader.readLine();
  
System.out.println("Enter PhoneNumber:");
int phone = Integer.parseInt(reader.readLine());
  
System.out.println("Enter EmailAddress:");
String email = reader.readLine();
  
this.accHolder = new Person(fName, lName, phone, email);
  
System.out.println("Enter Balance:");
int balance = Integer.parseInt(reader.readLine());
updateBalance(balance);
  
System.out.println(this.toString());
}catch(IOException e){e.printStackTrace();}
}
  
@Override
public String toString(){
return this.accountNumber +" "+ this.accHolder.getFirstName()+","+this.accHolder.getLastName()+","+
this.accHolder.getPhoneNumber()+","+this.accHolder.getEmailAddress()+", "+ this.balance;
}
}

public class MyClass {
public static void main(String args[]) {

Bank bn = new Bank();
bn.addBankAccount();
