NIT2112 – Object-Oriented Programming Semester 1, Block 2, 2021 LAB 1 Assessable Instructions: 1. Check the deadline in VUC. 2. Please submit your source code (.java) file(s) 3. Screen shout for your program and output in a word/pdf file . 3. Any late submission will receive 20% penalty. 4. Marking criteria is as followed:  Completed code according to the task – 10%  No compilation errors – 15%  No runtime errors – 15%  Correct logic to solve the problem – 30%  Correct code formatting, indentations and spacing applied – 10%  Sufficient comments added – 10%  Meaningful names used for variables and methods – 10% Q1. Write program calculate the final price of a purchased item using values entered by the user Hint: you are required to use formatting output for number, currency and percentage. --------------------[Print Receipt] ------------ - Enter the quantity: 6 - Enter the unit price: $1.98 - Subtotals: $10.14 - Tax: $ 0.61 at 6% - Total: $10.75 ------------------------------------------------ Q2. Write a program that prompts for and reads the users’ first name and last name, Job title, DOB (date of Birth), and the Email address (separately). Then create and print a random phone number of the form XXX-XXX-XXXX. Include the dashes in the output. Do not let the first three digits contain an 8 or 9 (but don’t be more restrictive than that), and make sure that the second set of three digits is not greater than 742. Hint: Think through the easiest way to construct the phone number. Each digit does not to be determined separately. ----------------------------[ User details] --------------------- - First name: Adam - Last Name: Hunter - Date of Birth: 20/02/1981 - Email Address: [email protected] - Phone number: 235-653-3541 --------------------------------------------------------------------- Q3. Write a program that reads three integers and prints their average. Q4. Write a program that reads two floating point numbers and prints their sum, difference, and product.
