Question

Here below are the requirement task of Individual Project 4 and Individual Project 5. Will you be able to finish Individual Project 4 by tomorrow and Individual Project 5 by this week friday? Also, Will you be able to do these homeworks by using Netbeans, because I really need to open that file in my Netbeans and check if those tasks are working as expected? Please reply asap.;INDIVIDUAL PROJECT 4 TASK;You have been tasked with creating an application that accepts product data and displays this information. The application also computes average sales and shipping charges. Using appropriate control structures, enhance your product class to include the 2 new methods designed in an earlier task.;The computeAverageSales() method should use sentinel-controlled repetition to allow a user to enter product sales data until the user has indicated that he or she is done. The average of the entered sales data will be computed and returned by the method to be displayed by the application. For example, if the user entered 500.50, 250.50, and 300.30, then the average sales would be computed for these 3 values and returned by the method. The prompting of the sales data is done within the method. If the value of the average sales exceeds $200.00, a message should be displayed to alert the user that the product has produced a significant amount of revenue. The computeAverageSales() method should return type "double.;The computeShippingCharges() method should use sentinel-controlled repetition, to allow a user to enter shipping data until the user has indicated that he or she is done. The total shipping charges will be computed and returned as a double value.;Modify your application to call the computeAverageSales() and computeShippingCharges() methods.;As a result of these modifications, the following requirements should be met;Your application should use the class you created in the earlier tasks. Your class represents one product that your by leass2opAy" href="http://www.homeworkmarket.com/messages/view/1871791#">COMPANY sells. Your class should have at least 3 attributes (instance variables). Getters and setters for each instance variable should be provided. Attributes should be appropriately typed and scoped to incorporate data hiding. Appropriate constructors should be implemented by each class and called by the application.;The application should provide a user-friendly interface that allows the user to input data for at least 2 instances of your product class.;Data validation should be incorporated at the time of data entry. At least one error-checking condition must be incorporated to allow the user to reenter a data value that is not valid.;Constructors should be called to create instances of your classes once the user has entered valid data. The valid data should be used appropriately by the constructors.;After product information has been entered and displayed, your application should allow the user to compute average sales and shipping charges. The application should call the computeAverageSales() and computeShippingCharges() methods.;There is no limit to the number of orders placed for each product. Using sentinel-controlled repetition, the computeAverageSales() method should allow a user to enter product sales data until the user has indicated that he or she is done. The average of the entered sales data will be computed and returned by the method to be displayed by the application. For example, if the user entered 500.50, 250.50, and 300.30, then the average sales would be computed for these 3 values and returned by the method. The prompting of the sales data is done within the method. If the value of the average sales exceeds $200.00, a message should be displayed to alert the user that the product has produced a significant amount of revenue.;The computeShippingCharges() method should use sentinel-controlled repetition to allow a user to enter shipping data until the user has indicated that he or she is done. The total shipping charges will be computed and returned as a double value. The application will display the computed shipping charges.;Design Document Requirements;Compile all of your pseudocode from the earlier IPs into a design document. Your design document should have a section that includes the functional requirements and any class diagrams used to describe the system. Include any design requirements imposed by your technical leadership. Your design document should be ready to post to the Week 4 Discussion Board for review by your classmates. In the next task, you will get an opportunity to receive suggestions for improvement on your design document.;INDIVIDUAL PROJECT 5 REQUIREMENT;Your company needs to provide your sales team with information on the products your company has sold. You will deliver an application that accepts product data and displays this information. Using the class you created in the earlier tasks, complete the design and development of your application.;Your application should use the class you created in the earlier tasks. Your class represents one product that your company sells. Your class should have at least 3 attributes (instance variables). Getters and setters for each instance variables should be provided. Attributes should be appropriately typed and scoped to incorporate data hiding. Appropriate constructor(s) should be created and called.;The application should provide a user friendly interface that allows the user to input sales data for at least 2 instances of your product class.;Data validation should be incorporated at the time of data entry. At least one error checking condition must be incorporated to allow the user to re-enter a data value that is not valid.;Constructor(s) should be called to create instances of your class once the user has entered valid data.;The interface should allow the display of the entered product information for each product. This information should display well formatted using a combination of printf(), print() and println() statements. Headers and labels should be used in the display to make it clear what each value displayed represents.;After product information has been entered and displayed, your application should allow the user to compute average sales and shipping charges. The application should call the computeAverageSales() and computeShippingCharges() method on your product class.;There is no limit to the number of orders placed for each product. Using sentinel controlled repetition, the computeAverageSales() method should allow a user to enter product sales data until the user has indicated that they are done. The average of the entered sales data will be computed and returned by the method to be displayed by the application. If the value of the average sales exceeds, $200.00, a message should be displayed to alert the user that the product has produced a significant amount of revenue.;The computeShipping Charges() method should use sentinel controlled repetition, to allow a user to enter shipping data until the user has indicated that they are done. The total shipping charges will be computed and returned as a double value. The application will display the computed shipping charges.;Your application should be by leass2opAy" href="http://www.homeworkmarket.com/messages/view/1871791#">WELL documented and developed using the principles covered in this course. All data displayed should be well formatted and presented in a readable manner.;A design document should be submitted that contains your UML class diagram of each class along with pseudocode for your methods and application.;Include a document that contains screenshots showing your application runs. Document each screenshot with a caption that explains the test data entered and the resulting application behavior/output.;True/False competency exam;The second part of the Key assignment is a competency test that will test your knowledge on fundamental data types, control structures, classes, objects, and methods. If you do not pass this competency exam you will not be able to proceed to the second Java course in this series.;A Scanner class can be used to read in user input.;Example syntax for creating a Scanner to read user input is;Scanner input = new Scanner("System.in");The println() statement can be used to provide a prompt to the user.;When using printf(), you can use %d as the format specifier for an int type.;An import statement, such as the one to import java.util.Scanner should be the very last line in an application.;You should always declare your instance variables as type public.;Getters are used to set the value of private instance variables.;Your application can use a getter to get the current value of an instance variable of an object that your application has created.;You must always have an else part for every ? if? statement.;The following code will result in the code repeated while i is less than 5, causing the value of i to be printed out as 5.;int i = 0;while (i<5);i++;System.out.printf("%d", i);?for? loops can never result in an infinite loop.;Pseudocode is helpful for algorithm development.;Example syntax for a 3 argument constructor for a Book class that takes an int value, a double, and a String;public Book (int num1, double num2, String name);bookId = num1, bookPrice = num2;title = name;Example call to the Book constructor from an application could be;Book myBook = new Book("5", "3.5", "The Rabbit Ran");A no argument default constructor will not be provided automatically by the Java compiler once you have declared your own constructor for a class.;Constructors should always have a return type of ?void?.;The eight primitive Java types are: boolean, String, int, char, double, float, long, byte.;A UML class diagram can be used to design your class.;Relational operators can be used to create the condition for an ?if? statement but never a ?while? loop.;In Java, && represents a Conditional AND operator.
