//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
