Creating Instance Methods and Driver Class

Monday, May 5, 2014

Objective: Create a class with instance data and instance methods.


Specifications: Create a BankAccount class. It should contain the following information, stored in instance variables:


First name: The customer’s first name.


Last name: The customer’s last name


Balance: The amount of money the customer has in the account.


It should have the following methods:


BankAccount(String firstName, String lastName, double openingBalance)


This constructor creates a new BankAccount


public String firstName()


Returns the customer’s first name


public String lastName()


Returns the customer’s last name


public double balance()


Returns the customer’s account balance


Create a driver to test your class. Create several accounts and verify that the first name, last name, and balance methods work properly.


I don't know if I did it correctly because I get no output at all...If I did it wrong please correct me. Thanks! Here is the code below.



public class BankAccount {
String firstName, lastName;
double balance;

public BankAccount(String firstName, String lastName,double openingBalance){

}
public String firstName(){
return(firstName);
}

public String lastName(){
return(lastName);
}

public double balance(){
return(balance);
}
}


Below is my "Driver" class



public class Driver {

static BankAccount acc1;

public static void main (String[] args){

acc1 = new BankAccount ("John","Tiger", 200);
}
}
