Array

The simplest way to start thinking about an array is as a collection, or a set of elements. In programming, these elements may be constants, variables, functions and pointers.

In previous chapters, you have created programs for the Greenville Idol competition. Now create a Contestant class with the following characteristics: The Contestant class contains public static arrays that hold talent codes and descriptions. Recall that the talent categories are Singing Dancing, Musical instrument, and Other. The class contains an auto-implemented property that holds a contestants name. The class contains fields for a talent code and description. The set accessor for the code assigns a code only if it is valid. Otherwise, it assigns I for Invalid. The talent description is a read-only property that is assigned a value when the code is set. Modify the GreenvilleRevenue program so that it uses the Contestant class and performs the following tasks: The program prompts the user for the number of contestants in this years competition; the number must be between 0 and 30. The program continues to prompt the user until a valid value is entered. The expected revenue is calculated and displayed. The revenue is $25 per contestant. The program prompts the user for names and talent codes for each contestant entered. Along with the prompt for a talent code, display a list of the valid categories. After data entry is complete, the program displays the valid talent categories and then continuously prompts the user for talent codes and displays the names of all contestants in the category. Appropriate messages are displayed if the entered code is not a character or a valid code.
Lab9C: 2D or not 2D For this exercise you will also be writing a program that will be building upon Lab9A. So please make new class file, copy, and rename the code you have already written for Lab9A. Please also rememb to rename the file and (and in the case of Java and C# students) class name to Lab9C. For this exercise, please take the array that was filled up with values and flatten it i.e., convert the 2-0 array to a 1-D array that contains the same values. Please do not just print the 2-D array to look li a 1-D array Hint: You will have to take the 2-D array's total amount of cells and make a 1-D array of the same siz Please refer to the sample output below for visualization and match its style. As always: Remember, the class name should be Lab9C. The user input is indicated in bold.

Create a class named "Hotel" (3 marks) - The class must have 4 attributes. (Choose any 4 attributes you want) - This class must have two constructors, Getter Methods, and Setter Methods. - toString() method should return the name of the hotel.  In the main class that has the main method: - In the main method, Create 4 objects or more from the class Hotel and store them in a normal array. (3 mark) - Create an external method that takes the array as an argument. It will add all the elements of the normal array into an ArrayList. Then, call the method to test it and print all elements data from the ArrayList
10. Lottery Application Write a Lottery class that simulates a lottery. The class should have an array of five integers named lotteryNumbers. The constructor should use the Random class (from the Java API) to generate a random number in the range of 0 through 9 for each element in the array. The class should also have a method that accepts an array of five integers that represent a per- son's lottery picks. The method is to compare the corresponding elements in the two arrays and return the number of digits that match. For example, the following shows the lotteryNumbers array and the user's array with sample numbers stored in each. There are two matching digits (elements 2 and 4). lotteryNumbers array: User's array: 7 4 4 2 1 3 7 3 In addition, the class should have a method that returns a copy of the lotteryNumbers array. Demonstrate the class in a program that asks the user to enter five numbers. The program should display the number of digits that match the randomly generated…

Create a class called Array for performing a float one dimensional array. Define all the necessary variables to represent the private part. Provide a constructor that enables an object of this class to be initialized when it's declared. The constructor should contain default size in case no initializers are provided which is 10. Provide a proper destructor. Provide public methods that perform each of the following tasks: Set the array values (Set). This function sets the array elements with a specific location. Get the array values (Get). This function returns the aray element with a specific location. Function called Max to get the maximum element of the array. Write a program to test your class. Define an object (array) with size 20 and another object with the default value. Fill the two arrays with values. Find the maximum number of the first array.
