1. Dice Histogram: Call your class DiceHistogram.java. In this exercise, you will simulate the throwing of 2 standard six-sided dice a given number of times and display the resulting distribution as a text-based histogram. First, ask the user how many time to roll the dice. Then simulate the dice rolling and print the maximum number of times a sum was rolled. Next print lines for each possible dice roll showing a number of asterisks proportional to the number of times the sum was rolled. Scale the number of asterisks such that the sum rolled the most will have 60 asterisks. Example transcript (user input underlined): How many rolls? 1000000 Max count: 166039 2 ********** 3 4 5 6 7 8 9 10 11 Possible "stepping stones" towards the goal: (1) Print the given number of roll sums. Remember: The sum of two 6-sided dice is different than a single roll of an 11-sided die numbered 2 through 12. (Why?) (2) Use an array to count the number of rolls for each sum and print a table (i.e. numbers instead of histogram asterisks above). (3) Compute and print the maximum count. (4) Round (60.0* count/maximum) for each count to compute the number of asterisks, and print the histogram as shown.

_4.1g Write a Java class that would match a string. The class has method match with String as a return type. It accepts two inputs: the phrase/sentence string (text) and the pattern string (word). This method finds the first (or all) instances of the pattern in the text and changes that word in all uppercase and return the new phrase. Method countOccurence accepts a phrase/sentence and a pattern string and returns its number of occurrences. Add a main method that will allow the user to input the phrase/sentence and pattern. Call method match and countOccurence. See test case below. Sample Input: Text string: You will always have my love, my love, for the love I love is as lovely as love itself. Pattern string: love . .

The goal of this coding exercise is to create two classes BookstoreBook and LibraryBook. Both classes have these attributes: author: Stringtiltle: Stringisbn : String- The BookstoreBook has an additional data member to store the price of the book, and whether the book is on sale or not. If a bookstore book is on sale, we need to add the reduction percentage (like 20% off...etc). For a LibraryBook, we add the call number (that tells you where the book is in the library) as a string. The call number is automatically generated by the following procedure:The call number is a string with the format xx.yyy.c, where xx is the floor number that is randomly assigned (our library has 99 floors), yyy are the first three letters of the author’s name (we assume that all names are at least three letters long), and c is the last character of the isbn.- In each of the classes, add the setters, the getters, at least three constructors (of your choosing) and override the toString method (see samplerun…

In this java assignment, we will be creating a paystub for an employee using classes, files, getters, and setters. Each file should only have one class and the class should share the same name as the file. We are going to implement the following classes: Employee - This class represent the employee. It needs the following fields exposed via getters and setters: Employee ID (hard code it to 1) First name, last name, middle initial Address, city, zip Phone, email Hourly rate PayPeriod - This class represents an employee's payment information. An employee will eventually have more than one pay period. It needs the following fields exposed via getters and setters: Pay period Id (hard code to 123456) Employee Id Start date, end date Number of hours PayrollManager - This class provides the functionality we need to compute and display the payroll. It should implement the following methods: double CalculateGrossPay (Employee, PayPeriod) - this should return the total gross for the…
Java Help Please! The Triangle series is a mathematical sequence of integers defined by the formula: triangle_number = Example: if we start with the integer 1, the series is: 1, 3, 6, 10, 15, 21, 28, 36, … Write a TriangleSeries class that implements Iterable. The TriangleSeries must have a constructor that allows us to specify the “start” number in the (sub) series we want to calculate, and the last number in the (sub)series. Also create a TriangleSequenceIterator that returns the proper integer in the series. Assume the starting value for the series is whatever start-value the client specified when they instantiated the TriangleSeries instance. Your iterator should return false for hasNext() when the “end value” is reached. For your convenience, here is the Iterator interface: interface Iterator<E> { boolean hasNext(); E next();}------ import java.util.Iterator;/** * Triangle Series Rule: t = n * (n + 1) / 2 */public class TriangleSeries implements Iterable<Integer>…

In Java Write a program that asks the user to enter how many automobiles are to bedescribed, and for each automobile, it (the driver) inputs the user’s selection ofmake and color. Then the driver outputs color and make. Although you could dothis easily using a simple procedural program, do it by using a main method inclass AutomobileDriver to instantiate an object called auto from a classAutomobile. Make your classes conform to the following UML class diagram:Let Automobile methods setMake and setColor do the prompting and inputtingfor make and color, and include input verification which asks again if a selectionis illegal. Let Automobile methods printColor and printMake print color andmake on one line. In AutomobileDriver, after asking auto to call setMake andsetColor, use auto.printColor().printMake(); to chain the two printing methods.Write code so that the program can produce the following display: Sample session:How many cars do you want to consider? 2 Select Buick, Chevrolet,…
