Lab 3 of 6: Inheritance and Applets

Hi, I need help with two coding problems.I have attached a zip file with have so far for the two codes. Below is a copy of the format to follow when creating the two programs.

iLab Overview

 

Scenario/Summary

In this lab, you will create one project that uses inheritance and one simple Applet.

Note!Software Citation Requirements

This course uses open-source software which must be cited when used for any student work. Citation requirements are on the Open Source Applications page. 
Please review the installation instruction files to complete your assignment

 

 

Deliverables

NOTE

Submit your assignment to the Dropbox, located at the top of this page. For instructions on how to use the Dropbox, read these step-by-step instructions.

(See the Syllabus section "Due Dates for Assignments & Exams" for due dates.)

Program files for each of the following programs

  1. InheritanceTest; and
  2. Greeting.

At the beginning of all your programs, put a comment box that includes the program name, your name, and a brief description of the program.

Example:

/*********************************************************************** 
Program Name: ProgramName.java 
Programmer's Name: Student Name 
Program Description: Describe here what this program will do 
***********************************************************************/

How to submit your assignment: 

  1. The programs must have the same names as the assignment title.
  2. Each Java source file (*.java) must include a corresponding class file (*.class) program as evidence of success.
  3. In addition to the program source code files and byte code files, put all your program source code files and screen shots of your program output files into a Word document.
  4. You must use a zipped folder to send your weekly assignment to the Dropbox. Do not send subfolders within your zipped folder. Place all of the .java and .class files for the week into the one zipped folder. The zip folder should be named CIS355A_YourLastName_iLab_Week3, and this zip folder will contain all the weekly programming assignments.

Lab Steps

 

Step 1: InheritanceTest

Implement an inheritance hierarchy based on the following specifications for Account class, Checking Account class, and Savings Account class:

 Account class

  •  Attributes:   
    • String Account Name  
    • Integer Account ID  
    • Double balance  
  • Methods:  
    • constructor:  initialize balance to zero
    • processDeposit ( ) – accepts a single double parameter containing the deposit amount. Updates the balance by adding the deposit amount to the balance.  
    • processWithdrawal ( ) – accepts a single double parameter containing the withdrawal amount. Updates the balance by subtracting the withdrawal amount for the balance. Note: For now do not worry about negative balances.  
    • sets and gets for name, account ID
    • getBalance to return the balance
    • displayAccount - this method prints all account information, here is an example:

                        Account:      2345 
                        Name:          John Smith 
                        Balance:      $120.75

  •  Attributes:   
    • String Account Name  
    • Integer Account ID  
    • Double balance  

TEST and make sure all methods of the Account class work before continuing!

The CheckingAcct class is a derived class of the Account class. 

  • It has no additional attributes
  • Overdraft withdrawls are allowed but the user is charged a $10 overdraft fee
  • No interest is earned
  •  Methods:
    • processWithdrawl() - needs to be overridden so that if the withdrawl causes insufficient funds, subtract $10 overdraft fee and display a message "overdraft fee charged".
    • displayAccount - this method prints all account information, here is an example:

                        Account type:  Checking 
                        Account:      2345 
                        Name:          John Smith 
                        Balance:      $120.75

The SavingsAcct class  is a derived class of the Account class. 

  • Overdraft withdrawls are not allowed
  • Interest is earned
  • No additional attributes
  • Methods: 
    • processWithdrawl() - needs to be overridden so that if the withdrawl causes insufficient funds, a message "insufficient funds" is displayed an no withdrawl is made.
    • calcInterest ( ) – If the account balance is greater than or equal to 5000.00 an interest rate of 4% or .04 is applied to increase the balance. If the balance is greater than or equal to 3000.00 an interest rate of 3% or .03 is applied to increase the balance. Otherwise use an interest rate of 2%. Return the interest amount.  This method should be called by displayAccount to show interest earned and add it to the balance.
    • displayAccount - this method prints all account information, here is an example:

                        Account type:                          Savings 
                        Account:                      2345 
                        Name:                         John Smith 
                                    Interest earned:           $5.02 
                        Balance:                      $250.75

 Main: 

To demonstrate polymorphism, create an arrayList of Account type that can handle Checking and Savings accounts (thiis is the Bank).  Prompt for name, account number (or assign account number in main) and add at least one checking object and one savings object to the bank array.  
Now use a loop to process all accounts USING THE Bank array:

  • Make an initial deposit in each account (prompt for amount to deposit)
  • Display the balance (to verify)
  • Make a withdrawl with sufficient funds (prompt for amount to withdraw)
  • Display the balance (to verify)
  • Make a withdrawl with insufficient funds (prompt for amount to withdraw)
  • Display the final account information using displayAccount

See example output below:

Creating a checking account, enter name: John Smith 
Your checking account number is 1000 
Creating a savings account, enter name: Sue Johnson 
Your savings account number is 1001 
Processing account: 1000 
Amount to deposit: 50 
Balance is 50.00 
Amount to withdraw: 25 
Balance is 25.00 
Amount to withdraw: 30 
$10 Overdraft fee charged! 
Balance is -15.00 
Account type: Checking 
Account: 1000 
Name: John Smith 
Balance: $-15.00 
Processing account: 1001 
Amount to deposit: 500 
Balance is 500.00 
Amount to withdraw: 150 
Balance is 350.00 
Amount to withdraw: 500 
Insufficient funds! 
Balance is 350.00 
Account type: Savings 
Account: 1001 
Name: Sue Johnson 
Interest earned: $7.00 
Balance: $357.00

Step 2: Greeting

Create an applet of size 500 by 500. The background color of the applet should be yellow. The four components to be included are

  1.  a Label object that has the text “Please enter your name;”
  2.  a Textfield object of size 20;
  3.  a Button object with the text "GREET;" and
  4.  a Label object with the text "Result goes here." This label will change to "Hello," followed by the entered name.

For this lab, you will need the actionPerformed method to provide event handling for the button.

The getText() method will be needed to get the string from the TextField.

The setText() method will be needed to change the text of the second Label.

Test your applet by entering your full name and confirming that the result label has changed. 

Test your applet by entering your full name and confirming that the result label has changed.
