In this assignment, you will need to add a new method to the Date class, which you
can find on D2L in the "Sample Code" section.
The new method should make a Date object's day, month, and year value change to
the next day. In other words, add one day to the object's current date. Do not use any
part of the built-in DateTime class, but you may want to use the DaysInMonth()
method from the Date class.
Examples:
• If the Date object stores the date 12/31/2021, then after calling your method
it should store the date 1/1/2022
• If the Date object stores the date 2/28/2022, then after calling your method it
should store the date 3/1/2022
As noted in the common instructions, you only need to turn in your new method, not
the entire Date class.
Method: sumOdds(value: int): This method will sum all the odd values from 1 upto the value passed by parameter. This will display the sumas an integer value.Method: characterCount(phrase: str): This method will count the number of characters in the phrase that is passed by parameter. You cannot useany built in function ( ie len() ) and must use a looping activity. This should display the number of characters inthe phrase as an integerMethod: multiplicationPractice(): This method is to practice simple multiplication problems. The program should randomly generate twonumbers from 1-10 for the user to multiply. It should display the multiplication problem and allow the user toanswer the problem. It should display if the user got the answer correct or incorrect. The activity shouldcontinue until the user has gotten 3 different practice problems correct.Method: order(value1: int, value2: int, value3: int): This method is to order the 3 passed value from least to greatest. It should display…

Probability differs in the roll of two dice compared to a single die due to varied combinations. Dice Roll Series: User greeted with "Welcome to the Dice Roll Stats Calculator!" and prompted to specify rolls. Java classes: DiceRoller, Indicator, Validator. DiceRoller: Arrays: rollSeries (captures results), statIndicators (stores statistical indicators). Constructor rolls dice as per user request. Methods collect stats and print the report. Indicator class: Contains dicePairTotal and dicePairCount. Displaying Results: Sort statIndicators array before display. Indicator objects sortable by dicePairCount (implements Comparable).

A magic square is a square matrix in which the sum of every row, every column, and both diagonals is the same. Magic squares have been studied for many years, and there are some particularly famous magic squares. In this exercise you will write code to determine whether a square is magic. File Square.java contains the shell for a class that represents a square matrix. It contains headers for a constructor that gives the size of the square and methods to read values into the square, print the square, find the sum of a given row, find the sum of a given column, find the sum of the main (or other) diagonal, and determine whether the square is magic. The read method is given for you; you will need to write the others. Note that the read method takes a Scanner object as a parameter.

Method: Print Write a method that prints the text representation of the foods in the array in reverse order (meaning from the end of the array to the beginning). Invoke this method from main. Method: Highest Sugar Food Write a method that takes an array of Food objects and finds the Food that has the most sugar. Note that the method is finding the Food, not the grams of sugar.

- Basic Java Help Each year, the Social Security Administration provides a list of baby names for boy and girls by state. You will write a program to read a file containing a list of baby names and display the top names. To start, implement the following class: baby names util = printTopNames(File, int): void printTopNames Will be a static method. It will accept two parameters, one is a File containing the list of names. The other is an integer that indicates how many names to display (ie, top 10 names, or top 50 names, etc). The integer argument could be any valid integer. You do not have to worry about an integer value large than 5 for the boy/girl names. This method should open the file and parse the file and print the names as shown below: Your program will use the Scanner class to read the data from the file (see your text for examples). You will also need to use a delimiter with the scanner so that the scanner will break the line apart based on the commas. For this file, set…arrow_forwardJava: Write a complete method to create an array of random integers. Method Specification The method takes in three integer parameters: the array size, the lower bound, and the upper bound. The method also takes in a boolean parameter. The method creates and returns an integer array of the specified size that contains random numbers between the lower and upper bound., using these rules: The lower bound is always inclusive. If the boolean parameter is true, the upper bound is also inclusive. If the boolean parameter is false, the upper bound is not inclusive (meaning it is exclusive). If any of the parameters are invalid, null is returned. Driver/Tester Program I have provided you with a driver/tester program that you can use to test your code before submitting.
