INSTRUCTIONS FOR THIS EXAM: 1. Open Netbeаns аnd clоse аll оpen prоjects (File / Close All Projects) 2. This question paper is to be answered using object-oriented programming principles. Your program must make sensible use of methods and parameters. 3. Make sure that you answer the questions in the manner described because marks will be awarded for your solution according to the specifications that are given in the question. 4. Only answer what is asked in each question. For example, if the question does not ask for data validation, then no marks are awarded for it, and therefore no code needs to be written for data validation. 5. If you cannot get a section of code to work, comment it out so that it will not be executed and so that you can continue with the examination. If possible, try to explain the error to aid the marker. 6. Your programs must be coded in such a way that they will work with any data and not just the sample data supplied or any data extracts that appear in the question paper. You are advised to look at the supplied data files carefully. 7. Make sure that routines such as searches, sorts and selections for arrays are developed from first principles, and that you do not use the built-in features of a programming language for any of these routines. 8. All data structures must be defined and declared by you, the programmer. You may not use components provided within the interface to store and later retrieve data. 9. Read the whole question paper before you choose a data structure. You may find that there could be an alternative method of representing the data that will be more efficient considering the questions that are asked in the paper. 10. You must save all your work regularly during the examination. 11. If your examination is interrupted by a technical problem such as a power failure, you will, when you resume writing, be given only the time that was remaining when the interruption began, to complete your examination. No extra time will be given to catch up on work that was not saved. 12. Make sure that your name appears as a comment in every program that you code.
7.1 Write cоde tо creаte а receipt methоd thаt will receive the name of a customer in the format: InitialSurname, and return the name of that customer, their orders and the totals as shown below. Only one customer has made two purchases: Ingrid Harodi. The method must return both purchases when tested with “I. Harodi”. If the customer is not found, then an appropriate message must be returned. (You may add code to previous classes as required). For Example, a search for M. Mbata will return the following: ORDERS FOR: M. Mbata M. Mbata 2023-04-15 true DRINKS ORDERED:Dulce VitaDUL03 Juice, 2 @ R30.0 Total: R60.0TOTAL: R 60.0DISCOUNT: R 0.0FINAL AMOUNT: R 60.0 [9] 7.2 The shop’s owner wants to contact all customers who have not bought any drinks for more than 30 days. Add code to create a method, cust30Days() which will return a string with headings and the names of these customers in the format shown below: (You may add code to previous classes as required). Example: CUSTOMERS WHO HAVE NOT BOUGHT FOR 30 DAYS or MORE: [6]
