Object-oriented programming (OOP)

Object-oriented programming (OOP) is a programming paradigm based on the concept of objects fundamental to many programming languages, including Java and C++. OOP can be devided in two sub types: class-based (or “classical”) and prototype-based OOP (found in JavaScript, for example).

Object-oriented programming has several advantages over procedural programming:

https://github.com/bell-kevin/checkingaccount

You created a Savings Account in the examples. In this project, create a Checking Account. A Checking Account has a current balance and a fee charged for each transaction. The transactions are making a deposit and making a withdrawal. In this project, use a loop to let the user select different transactions. Assume all data entered will be valid – positive numbers, and not greater than the current balance in the account. Create a project named Ch6Checking. Create a class named CheckingAccount. In the methods for withdrawal and deposit, after adjusting the balance by the amount of change, subtract the fee. In the driver class, create a CheckingAccount object named checking, and ask the user for the beginning balance and the fee for this checking account. In a loop, ask the user to select options to deposit, withdraw, or quit. Use a Switch structure to process the choice. Print the new balance after each transaction, with properly formatted numbers. Note the placement of dollar signs before the user input. That is printed by your code, the user does not type a dollar sign. Take a screenshot of the execution that matches the sample session. Run it again and do a withdrawal first, then a deposit, and take a screenshot of that session. Submission: the specified screenshots, and the root folder for the project Pay careful attention to the rubric for this assignment. Remember the standards that apply to every project. Note that you must use correct formatting in the code -- appropriate indentation is most important. You can use Shift-Alt-F to have NetBeans automatically format the code correctly. If the formatting is incorrect, it will be returned to you for changes with a grade of zero. Note: You need to submit the whole project for these assignments. In File Explorer, go to the location where you created the project. There will be a folder with the name of your project -- that is the root folder of the project. If you submit the root folder of the project, the instructor can run it on a different machine to grade it. If you don't submit the proper folder, it won't run on another machine, and the assignment will be marked with a zero.

https://github.com/bell-kevin/circle

Create a project that has a Circle class. The Circle class should contain: -One instance variable – radius -A method named setRadius that assigns the passed-in radius value to the radius instance variable -A method named initialize that prompts the user for a radius value and then assigns the entered value to the radius instance variable. (Note that the method will prompt the user, not the driver class.) -A method named printCircleData that uses the circle’s radius to calculate the circle’s diameter, circumference, and area and print the results. Use the Java API constant Math.PI for the value of pi. Use local variables to store the diameter, circumference, and area. Print the circle’s radius, diameter, circumference, and area. Create a Driver class (the main class) that tests all of the variables and methods of the Circle class. In that driver class, create a circle object and name it “spot”. Initialize it, print the circle data, then set the radius to a different specific value, and print the circle data again. In the first example, the driver class contained the interaction with the user, asking for the necessary values, then passed that data to the methods in the class. In this example, the method initialize in the class contains the interaction with the user, asking for the radius. How do you decide where the user interaction goes? It’s often best to put those interactions in the class, because it makes the driver class shorter and easier to understand, and it adds documentation to the class. But you can put those interactions in either location, as we demonstrated with these examples. As in the first example, create a project – name it “Example2Circle”, and the IDE will provide you with the starting structure for the main class, the driver class. If you know what code you need in the driver class, you can go ahead and type it now, and you’ll get a lot of errors because none of the class references exist yet. It’s usually better to create the class and enter its code first, then come back to the driver class to write the code that tests the class. In the File menu, click on New, then File, and create a new Java class named “Circle”. Write the necessary code to create the instance variable radius, and the methods to initialize, set the radius, and print the results, as described. Here is the Driver class code. Note that every method in the Circle class is tested. The initialize method will ask the user for the radius and set it, then the driver prints out the results for that circle. Next, the driver executes the method to change the radius to a different value, and prints out those results.

https://github.com/bell-kevin/ch6savingsaccount

This project is very similar in design to the Mouse2 class and Mouse2Driver example in the book (Introduction to Programming with Java: A Problem Solving Approach, Second Edition by John Dean and Raymond Dean). Remember the project in Ch 4 about calculating the value of an account as it grows, which was enhanced in Ch 5 to look better? We’ll do the same work here but using OOP methodology. In this project, the user will specify the starting balance for a savings account, the interest rate, and the number of cycles it will grow at that interest rate. The program will display how much the account is worth at the end of that growth. We need a class that provides the blueprint for this savings account. What kind of variables do we need? The current balance is essential. Since this is a savings account that grows by adding earned interest, we need the value for the interest rate to be able to calculate that earned interest. You might want to know the customer who owns this account – but notice that the customer is the owner, not part of the account. Therefore, the customer info is not part of this account. So the data needed to provide the information about the account and its current state is balance and interest rate. What actions can this account take, what can it do? The first thing needed will be setting the balance and the interest rate, so we need “mutator” or “set” methods for those actions. We need to be able to see the balance, which is an “accessor” or “get” method. Is there any other method required for this class? We could stop here, and “grow” the account in the driver class or main method. But that doesn’t make the best use of OOP design and programming, so we’re going add a method to the class to “grow” the account. Next, consider if the instance variables are public or private – protected or open to the world? If you want methods outside of this class, other programmer’s methods, to be able to change the variable directly, then make it public. Most of the time, you’ll want to protect the variable, make sure it’s changed only by the methods provided in the class. For this account, we certainly want to protect the balance and interest rate, so they need to be private. Add a minus sign or hyphen in front of those two variables in the UML diagram to represent that access. Next consider the data type for each variable – double or integer? The balance is money, and interest rates require decimals, so the variables need to be doubles. The next step is to consider the methods. Are they private or public, available to the world outside of this class? All of them need to be public, because we are going to execute them from the driver class, which is outside of this class. What type of data will each method return? The “get” method will return the current value in the instance variable for balance, so it must return a double, matching data type of that variable. The two “set” methods don’t need to return anything, so their return type is “void”. The growAccount method is going to do work to change the account balance – does it need to return anything? No, its results will be in the balance variable, and we can get that number with the get method. So the growAccount method is also void. Do any of those methods need information passed into them when they are called? Usually the “set” methods need data to change the values in the variables. Here, we need to know the starting balance, the interest rate, and the number of cycles to grow the account, information provided by the user. For this project, we are going to use the driver class to ask the user for all that information. Therefore the driver class needs to pass the data to the methods in this class – the data will be provided to the method inside of its parentheses. The setBalance and setInterestRate methods need doubles passed to them. The growAccount method needs an integer for the number of cycles to grow the account. Begin by creating a new project and name it “Ch6SavingsAccount”. The IDE provides you the main class heading, which is the driver for this project. We’ll code that later; first, we need the class that will be the basis for that driver. In the File menu, click on “New File” – not new project, new FILE. Specify that the File Type is “Java Class”, and name it “Account”. This is the name of the class – the file name must match the name of the class. The IDE has again given you the starting point for this type of file. Now that the class exists, turn your attention to the driver or main code. What needs to happen here? The user needs to provide the starting balance, interest rate, and number of cycles to grow the account. As you have done in previous projects, you’ll ask the user to enter the necessary information. Take a moment to consider the interest rate value. The interest rate must be a double because it is a fraction of one whole unit. If someone says an interest rate is 7%, we don’t use “7” for the calculations – we use 7 / 100. Always make it clear to the user if they are supposed to enter percentage rates (7 for 7%) or the mathematical percentage (0.07 for 7%). It is usually best to have the user type it as if there was a percent symbol following it – 7 for 7% makes a lot more sense to a user than 0.07 for 7%. If the user types in a number like 7, you must do the math in the program to convert that to its decimal equivalent of 0.07 – divide the interest rate by 100. That code is in the class above. Notice that there are variables for balance, interest rate, and cycles in this driver class, which seem like a repetition of the instance variables in the Account class. The variables in the driver class are used to communicate with the user, to get the data to pass to the Account class to create a specific account. As discussed in the book, we could use different names for the variables, like “newBalance” or “inputInterestRate”, and sometimes that is helpful to make it very clear what data is being stored in each variable. But they really are the same data here, so we’ll use the same variable names in the driver class and the Account class. The prefix “this.” in the Account class helps to clarify that the data passed into the method is assigned to the private instance variable in the Account class.
