Give an example of a while loop, then provide the equivalent do-while loop and for loop. Then give a different example of a do-while loop, along with the equivalent while loop and for loop. Finally, give an example of a for loop, along with the equivalent while loop and do-while loop. Use your examples to illustrate the advantages and disadvantages of each looping structure, and describe those advantages and disadvantages.

In this assignment, you will write a program that asks the user a quiz question and prompts them for an answer until they get the question correct. This program will be the basis for future Programming Assignments in this course.

These instructions assume you are using the Eclipse IDE on your own computer. You may use a different Java environment as long as you can provide your Java code and screenshots for your assignment submission.

Write a JAVA program that will input the following data : Student Name, Average, Tuition Fee and output
Total Tuition Fee :
Formula : Total Tuition Fee = Tuition Fee - Discount
If Average is : 95 -100 100% Discount
90-94 25%
85-89 10%
84 and Below no Discount

Define a class named TemperatureConverter. The class has two accessors “toFahrenheit” and “toCelsius” that return the temperature in the specified unit and two mutators “setFahrenheit” and “setCelsius” that assign the temperature in the specified unit.
Using this class, write a program that inputs temperature and converts from Fahrenheit to Celsius and Celsius to Fahrenheit.
Formula:
1. Fahrenheit to Celsius
T(°C) = (T(°F) - 32) × 5/9
2. Celsius to Fahrenheit
T(°F) = T(°C) × 9/5 + 32

Write a program that computes the total ticket sales of a concert. There are three types of seating’s: A, B, and C and the price of a ticket for each of the three types of seats are 3000 Rs ,2000 Rs , and 1000 Rs respectively. The program accepts the number of tickets sold in each category. The total sales are computed as follows:
totalSales = numberOfA_Seats * pricePerA_Seat + numberOfB_Seats * pricePerB_Seat + numberOfC_Seats * pricePerC_Seat;

Tono loves to do shopping. Today, she went to the market where there are N different types of products. She wants to buy exactly K of them at the minimum cost. Although she is super smart, she wants to check your smartness as well. Can you tell her the minimum cost required to buy exactly K products if she has already decided to buy product J.

Create a flowchart that will accurately represent the logic contained in the
scenario below:
“A program needs to continue prompting a user to enter a number until the total
of all values entered are no longer less than 100.”

1. RetailItem Class
Write a class named RetailItem that holds data about an item in a retail store. The class should have the following fields:
• description. It is a String object that holds a brief description of the item.
• unitsOnHand. It is an int variable that holds the number of units currently in inventory.
• price. It is a double that holds the item’s retail price.
Write appropriate mutator methods that store values in these fields and accessor methods that return the values in these fields. Once you have written the class, write a separate program that creates three RetailItem objects and stores the following data in them.

Description Units On Hold Price
