- Create a class name Taxpayer. Data fields for Taxpayer include yearly gross income and Social Security number (use an int for the type, and do not use dashes within the Social Security number). Methods include a constructor that requires a value for both data fields and two methods that each return one of the data field values. Write an application named USeTaxpayer that declares an array of 10 Taxpayer objects. Set each Social Security number to 999999999 and each gross income to zero. Display the 10 Taxpayer objects. Save the files as TAxpayer.java and USeTAxpayer.javaTrue or False? Arrays cannot be passed as parameters, but must be used only in the main method.Create a Golf Game. Allow for two players. Prompt for the player names. Each player plays 18 holes. Use an array or List for each player to hold their number of swings for each hole. Logical methods should be implemented for different tasks (broken out below). It is up to you to determine the parameters and return types of each method as appropriate. Method 1 - For each hole, the player has a number of swings. Determine the player's swings by generating a random number between 1 and 4. Store each players number of swings in the array/list. Method 2 - After completing the 18 holes, add up the number of swings for each hole for each player. The player with the fewest number of swings is the winner. Method 3 - Save the game data into a CSV file in the main project (root) directory. Name the file "Golf_Game_Player1_Player2.csv" using the player's names. The information in the file should look like this: playername, scoreforhole1, scoreforhole2, scoreforhole3, etc... Method 4 - In the…
- 1. A method called convertFromDecimal which takes two integers as parameters. The first integer is the decimal number to be converted and the second integer is the base to be converted to. The base value could be any number between 2 (binary) and 16 (hexadecimal). The converted number is returned as a String. Hints: • Remember that in order to convert a decimal number that includes only an integer part to a base n, you need to use repeated integer division of successive quotients on n saving the remainder in each step until the quotient is zero. • Remember that numbering systems with bases 11-16 use letters in order to continue counting after the digit 9. For example, the numbering system with base 12 has the following digits: {0,1,2,3..9,A,B}. ...... 2. In your main method declare and initialize an integer. Then print its representation in all numbering systems from 2-16 by invoking the method convertFromDecimal. You should use a for loop for this part.Carly’s Catering provides meals for parties and special events. In previous chapters, you have developed a class that holds catering event information and an application that tests the methods using four objects of the class. Now modify the Event and EventDemo classes as follows: Modify the method that sets the event number in the Event class so that if the argument passed to the method is not a four-character String that starts with a letter followed by three digits, then the event number is forced to A000. If the initial letter in the event number is not uppercase, force it to be so. Add a contact phone number field to the Event class. Add a set method for the contact phone number field in the Event class. Whether the user enters all digits or any combination of digits, spaces, dashes, dots, or parentheses for a phone number, store it as all digits. For example, if the user enters (920) 872-9182, store the phone number as 9208729182. If the user enters a number with fewer or more…● Create a class named Decimals. Write a static method named printDecimalDigits that takes a double as a parameter and does not return anything. ● ● ● The method should print out "Digits after decimal point: ", followed by all the digits after the decimal point on one line (do not include the decimal point). Additional rule: Your code must not contain any loops. Create a test class named DecimalsTest that contains the main method and use the sample usage below to check your code. Method Call Decimals.print DecimalDigits (37.2) Decimals.print DecimalDigits (1000) Method Output Digits after decimal point: 2 Digits after decimal point: 0 Decimals.printDecimalDigits (18.3927493038) Digits after decimal point: 3927493038
- Modify the Percentages application whose main() method holds two double variables. Assign values to the variables. Pass both variables to a method named computePercent() that displays the two values and the value of the first number as a percentage of the second one. For example, if the numbers are 2.0 and 5.0, the method should display a statement similar to “2.0 is 40.0 percent of 5.0.” Then call the method a second time, passing the values in reverse order. For testing use the values 2.0 and 5.0. An example of the program is shown below: 2.0 is 40.0 percent of 5.0 5.0 is 250.0 percent of 2.0There are a number of national and state parks available to tourists. Create a Park class. Include datamembers such as name of park, location, type of (i.e., national, state, local) facility, fee, number ofemployees, number of visitors recorded for the past 12 months, and annual budget. Write separateinstance methods that a) return a string representing name of the park, the location and type of park;b) return a string representing the name of the park, the location and facilities available; c) computecost per visitor based on annual budget and the number of visitors during the last 12 months; and d)compute revenue from fees for the past year based on number of visitors and fee. Also include aToString( ) method that returns all data members with appropriate labels. Create a second class totest your Park class.3. Create a program for Smalltown Regional Airport Flights that accepts either an integer flight number or string airport code from the options in Figure 8-33. Pass the user’s entry to one of two overloaded GetFlightInfo() methods, and then display a returned string with all the flight details. The method version that accepts an integer looks up the airport code, name, and time of flight; the version that accepts a string description looks up the flight number, airport name, and time. The methods return an appropriate message if the flight is not found. Farrell, Joyce. Microsoft Visual C#: An Introduction to Object-Oriented Programming (MindTap Course List) (p. 347).

- Write a method that calculates and prints both the maximum humidity and maximum temperature values from the abq_weather_cleaned.csv data set. You should write your method in the data Visualization class we have been working on in lecture. Your method should use all of the variables that are already part this program. In particular, you will need to use the data array variable. Your method should return nothing and take no input parameters; it's signature should be void max (). Your print outs should look like this: The max humidity is: 58 The max temperature is: 70Write a method that calculates and prints both the maximum humidity and maximum temperature values from the abq_weather_cleaned.csv data set.

All the methods you create will be static. Only two methods (mentioned below) and the main method need to be public. Any other methods that you write to help these methods should be private because they are only used internally within the class. Requirements: 1. Prompt users to enter 3 string inputs. Consider strings with alphabetic characters (a - z, A - Z) and/or numbers (0 - 9) as valid. Strings contain only non-word characters are invalid. Print the following usage when an input string is invalid or is empty. Usage: Enter a string that contains alphabetic characters and numbers 2. Create a method "isPalindrome" that takes a String as a parameter and returns true if the given String parameter is a palindrome and false if it is not. In your main method, this method should be call with the first user input and print either "The given string is a palindrome." or "The given string is not a palindrome." as…
