public class Bank Account { //class definition

private String name; //private String type field to hold name

private double balance; // private double type field to hold balance

public Bank Account(String name, double balance) { // parameter constructor that takes

//this keyword is used to refer to the data members name and balance and to avoid confusion between name, balance private member fields and constructor arguments name, balance

this.name = name;

this.balance = balance; }

public void deposit(double amount) { //method to deposit amount

balance = balance + amount; } // adds the amount to the account causing the current balance to increase

public void withdraw(double amount) { //method to withdraw amount

balance = balance - amount; } //subtracts the amount causing the current balance to decrease

public String toString() { // to display the name and current balance

return name + " , $" + balance; } } //returns the name and the current balance separated by a comma and dollar
