Write a class named StockPrice. The class constructor should accept an array of stock prices as its argument. The class should have a method that returns the average of the stock prices. If any stock prices in the array is at least 300, the class should throw an IllegalArgumentException.
Challenge 3: Scores.java and TestScores.java
Implement a Scores class. The class constructor should accept an array of scores as its argument. The class should have a method that returns the average of the scores. If any score in the array is negative or greater than 100, the class should throw an IllegalArgumentException.
Implement a TestScores class that creates an array and fills it with numbers given by the user. It should catch the exception thrown when the user enters an illegal value.
Write code for PersonManagement class. This class contains the array of Person class (code is given below) and also following methods:
set: This method receives the array of person class and set the attribute.
displayAll: This method will display values of all persons.
sort: This method will sort the array according to age values of the persons with ascending order using Selection Sort.
reverse: This method will reverse the order of the array.
getPersons: This method will return the array of the persons (attribute).
displayEvenAgePerson: This method will display all those persons values who have even age.

- 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.arrow_forwardWrite code for PersonManagement class.

(It stands for growable self-sorting array)This object will manage an array of type int. Create a private variable for an array of type int. In the constructor for this object, take in an int value which will determine the starting size of the array. The constructor should also instantiate the array.Create a public method called insert, which will take in an int and find the location in the array where it belongs and insert it there. If the array is full, then before inserting the value, method insert should call private method increaseSize, which will create a new array which is double the size of the current array. Then it will copy the values from the original array into the new array and set the private variable to this new array.The array should keep track of how many of its indexes are filled. Create a private variable called lastindex which will be equal to the last index of the array that has a value.Create a public method delete, which will…arrow_forward

- Task #1 Average Class-Create a class called Average according to the UML diagram. Average: -data [ ] :int -mean: double +Average( ): +calculateMean( ): void +toString( ): String +selectionSort( ): void This class will allow a user to enter 5 scores into an array. It will then rearrange the data in descending order and calculate the mean for the data set. Attributes: -data [ ]— the array which will contain the scores -mean — the arithmetic average of the scores Methods: -Average — the constructor. It will allocate memory for the array. Use a for loop to repeatedly display a prompt for the user which should indicate that user should enter score number 1, score number 2, etc. Note: The computer starts counting with 0, but people start counting with 1, and your prompt should account for this. For example, when the user enters score number 1, it will be stored in indexed variable 0. The constructor will then call the selectionSort and the calculateMean methods. calculateMean — this is a…arrow_forward(TicTacToe Class) Create a class TicTacToe that will enable you to write a complete programto play the game of tic-tac-toe. The class contains as private data a 3-by-3 two-dimensional arrayof integers. The constructor should initialize the empty board to all zeros. Allow two human players.Wherever the first player moves, place a 1 in the specified square. Place a 2 wherever the second player moves. Each move must be to an empty square. After each move, determine whether the gamehas been won or is a draw. If you feel ambitious, modify your program so that the computer makesthe moves for one of the players. Also, allow the player to specify whether he or she wants to go firstor second. If you feel exceptionally ambitious, develop a program that will play three-dimensionaltic-tac-toe on a 4-by-4-by-4 board. [Caution: This is an extremely challenging project that couldtake many weeks of effort!]arrow_forwardDefine a class called Book. This class should store attributes such as the title, ISBN number, author, edition, publisher, and year of publication. Provide get/set methods in this class to access these attributes. Define a class called Bookshelf, which contains the main method. This class should create a few book objects with distinct names and store them in an ArrayList. This class should then list the names of all books in the ArrayList. Enhance the program by providing a sort function, which will sort the books in ascending order of their year of publication. Create a few more Bookobjects with the same names but with different edition numbers, ISBNs, and years of publication. Add these new Book objects to the ArrayList, and display the book list sorted by book name; for duplicate books of the same name, sort the list by year of publication. (Hint: You will need to define a comparator class that takes two Book objects as parameters of the compareTo This method should do a two-step…arrow_forward
- Java Code Write a program in which you create a class called TextFileReader. The TextFileReader class must contain an instance variable consisting of an array of Strings 100 elements long. TextFileReader should have two constructors: a default constructor and a constructor that takes a String argument, which represents the name of a text file to be opened and read into the array of Strings. The first (default) constructor does not really do anything. If the second constructor is used, it will open the file and read the contents of the file into the array of Strings as follows: fill the array by having your program read one line of the file into each string until you have filled the array. Once the array is full, you may stop reading the input file. Add a member function contents(), which will convert the array of Strings into a single StringBuffer, which is then returned to the calling program so that it may be displayed. Add a second member function display(), which prints the array…arrow_forwardYou are required to design an Movie class which has following attributes String title; String director; Int duration; String release_Date; Provide default & Parameterized constructors. Provide getters & setters for data members. Provide a toString() method to print values. Now create an array of Movie store values in it (take values form user). After that you have to print the following All the movies in the array. Movie’s whose name starts with ‘a’; Movie with longest duration. All the movies having release date before 25-3-2021.arrow_forwardShift Left k Cells Consider an array named source. Write a method/function named shiftLeft( source, k) that shifts all the elements of the source array to the left by 'k' positions. You must execute the method by passing an array and number of cells to be shifted. After calling the method, print the array to show whether the elements have been shifted properly. Example: source=[10,20,30,40,50,60] shiftLeft(source,3) After calling shiftLeft(source,3), printing the array should give the output as: [ 40, 50, 60, 0, 0, 0 ]arrow_forward
