// CSE 142, Autumn 2010, Marty Stepp
// This class defines a new type of objects called BankAccount.
// Each BankAccount object represents one user's account at a bank,
// including the account balance, personal info, and so on.
// BankAccount objects include behavior for making transactions on the account
// such as deposits and withdrawals.

public class BankAccount {
    // fields - the variables in each object
    int number;
    double balance;
    int ssn;
    String name;
    int pin;
    String address;
    
    // Deposits the given amount from this bank account.
    // If the amount is negative, the transaction is aborted.
    public void deposit(double amount) {
        if (amount > 0.0) {
            balance = balance + amount;
        }
    }
    
    // Withdraws the given amount from this bank account.
    // If the amount is negative or the account does not have that much money,
    // the transaction is aborted.
    public void withdraw(double amount) {
        if (amount > 0.0 && amount <= balance) {
            balance = balance - amount;
        }
    }
    
    // Returns a String representation of this bank account object,
    // so that it can be printed.
    // Example: "Marty: $5.25"
    public String toString() {
        return name + ": $" + balance;    
    }
