Write a java program that simulates a vending machine. Products can be purchased by inserting coins with a value at least equal to the cost of the product. A user select a product from a list of available products, add coins, and either gets the products or gets the coins returned. The coins are returned if insufficient money was supplied or if the product it's sold out. The machine does not give change if too much money was added. Products can be restocked and money remove by an operator. Your solution should include a class VendingMachine that is not coupled with the Scanner or PrintStream classes.
PS: For the VendingMachine.java, using public ArrayList<Product> getProductList(){ ArrayList<Product> list = new ArrayList<>();}
instead of public ArrayList<String> getProductList(){ ArrayList<String> list = new ArrayList<String>();}

- Read the following scenario: To implement an exam, an instructor first notifies the students of the exam date and the topics to be covered. The instructor will prepare the exam paper, gets it copied to produce enough copies for the class, and hands it out to students at the designated time and location. The students attempt their answers to exam questions and hand in their answer papers to the instructor. The instructor then gives the answer papers to the tutor, along with sample solutions to each question, and gets them to mark it. The tutor will then records all the marks and return the answer papers to the students. After the answer papers have been returned to the students, they can raise any issues or queries about the marks they received. The instructor then reviews these queries/issues and decides whether marks adjustments are needed. If there are marks adjustments, the instructor will request the tutor to make the necessary changes in the marks record.

The program will randomly generate the cards dealt to the player and dealer during the game. Cards in this game will be represented by numbers 1 to 13 with Ace being represented by a 1. Remember, that face cards (i.e. Jack, Queen, and King) are worth 10 points to a hand while an Ace can be worth 1 or 11 points depending on the user’s choice. The numbered cards are worth their number value to the hand. Here are the details of how to play the game: To start the game, the player is given two randomly chosen cards and told their values. The dealer is then given two cards randomly. The human player should only be told the value of the first card given to the dealer. The other card in the dealer's hand is "hidden" until the end of the game. The player is then asked if they want to draw another card for their hand.

The program asks each traveller what their hotel is (the choices are the Seaview for which they need to join Queue 1, the Majestic for which they need to join Queue 4 and the Grand for which they need to join Queue 7) and tells them the right queue. There are 1330 travellers with the tour company and each will use the program as they arrive. After all have indicated their hotel, the program then prints the percentage in each hotel. * See image for an example run of the program. Percentages should be printed truncated to two decimal places. Do this using a method you write yourself that multiplies by 100, converts to an integer then divides by 100. * must make use of a counter-controlled for loop, be in procedural programming style (not OOP)arrow_forwardCreate a cashiering system in Java that applies the OOP concept.

Your calculator should have functions for: addition, subtraction, multiplication, division, modulo, exponent function(^). Use oop technique and create a class called calculator that provide unique method body for each problem. Thus, your class should have six different method for these (addition, subtraction, multiplication, division, modulo, exponent function(^)) and use the GUI for user interaction.arrow_forwardNote: write a java program given below.
