- The following block of code is intending to display the values that store in array. public static int[] CO{ int[] arr={3,4,66,90}; int[] b=A(arr,4); return b; } public static int[] A(int[] arr, int size) { int[] x=new int[size] ; for(int a=0; aIn C#, how would you write (2) programmer defined methods as described below: Method #1 (GreetingGeneric) — a type void programmer defined method does not require any parameters. It should output a generic greeting line for a letter. For example: "Dear Customer", "Dear Student", etc. Method #2 (GradeMessage) — a type void programmer defined method that has (3) parameters; (string, string, double) for (name, assignment, and grade) and should output the passed parameters in sentence format: GradeMessage("Jimmy", "Midterm Exam", 79.5) would output: Jimmy took the Midterm Exam and got 79.5 points. The Main() method for this program should: call Method #1 to output the generic greeting ask the user to enter a name, assignment, and grade and pass them to Method #2 for output. Input should only be done in the Main() method and output in the programmer-defined methods.Ag 1- Random Prime Generator Add a new method to the Primes class called genRandPrime. It should take as input two int values: 1owerBound and upperBound. It should return a random prime number in between TowerBound (inclusive) and upperBound (exclusive) values. Test the functionality inside the main method. Implementation steps: a) Start by adding the method header. Remember to start with public static keywords, then the return type, method name, formal parameter list in parenthesis, and open brace. The return type will be int. We will have two formal parameters, so separate those by a comma. b) Now, add the method body code that generates a random prime number in the specified range. The simplest way to do this is to just keep trying different random numbers in the range, until we get one that is a prime. So, generate a random int using: int randNum = lowerBound + gen.nextInt(upperBound); Then enter put a while loop that will keep going while randNum is not a prime number - you can…Charge Account Validation Using Java programming Create a class with a method that accepts a charge account number as its argument. The method should determine whether the number is valid by comparing it to the following list of valid charge account numbers:5658845 4520125 7895122 8777541 8451277 13028508080152 4562555 5552012 5050552 7825877 12502551005231 6545231 3852085 7576651 7881200 4581002These numbers should be stored in an array. Use a sequential search to locate the number passed as an argument. If the number is in the array, the method should return true, indicating the number is valid. If the number is not in the array, the method should return false, indicating the number is invalid.Write a program that tests the class by asking the user to enter a charge account number. The program should display a message indicating whether the number is valid or invalid.JAVA PROGRAM Chapter 7. PC #1. Rainfall Class Write a RainFall class that stores the total rainfall for each of 12 months into an array of doubles. The program should have methods that return the following: • the total rainfall for the year • the average monthly rainfall • the month with the most rain • the month with the least rain Demonstrate the class in a complete program. Main class name: RainFall (no package name) est Case 1 Enter the rainfall amount for month 1:\n1.2ENTEREnter the rainfall amount for month 2:\n2.3ENTEREnter the rainfall amount for month 3:\n3.4ENTEREnter the rainfall amount for month 4:\n5.1ENTEREnter the rainfall amount for month 5:\n1.7ENTEREnter the rainfall amount for month 6:\n6.5ENTEREnter the rainfall amount for month 7:\n2.5ENTEREnter the rainfall amount for month 8:\n3.3ENTEREnter the rainfall amount for month 9:\n1.1ENTEREnter the rainfall amount for month 10:\n5.5ENTEREnter the rainfall amount for month 11:\n6.6ENTEREnter…Please code in python Create a program with two classes – the person class and the student The person class has the following properties: first name (first_name), last name (last_name) street address (address) city (city) zip code (zip) The class has the following methods: get_full_name, which returns the full name of a person get_full_address, which return greeting, returns a greeting message. The class should provide accessor and mutator for each property The class should override the __str__ method to return the state of the object. Create a child class called student which has a property named graduation year (graduation_year) and major. Provide accessor and mutator for each property of its own It inherits all the properties and methods of the person parent class as well. Create a test program that Create an object of the person class and print the full name of a person. Create an object of the person class and print…Question 6 Consider: class Bike { } private String color; public Bike() { } public Bike(String newColor) { color = newColor; } public Bike (Bike bike) { color = } bike.color; public String getColor() { } } return color; public void setColor(String newColor) { color = newColor; Bike bike1= new Bike(); = Bike bike2 new Bike("blue"); Bike bike3 = new Bike(bike2); bike2.setColor("green"); Bike bike4 = new Bike(bike2); Which of the following are correct? bike4.getColor() returns null bike4.getColor() return "blue" bike3.getColor() return "green" bike2.getColor() returns "blue" bike4.getColor() return "green" bike1.getColor() returns bike3.getColor() return null bike3.getColor() returns "blue" bike2.getColor() returns "green" bike1.getColor() returns nullQUESTION 24 If an array is declared at the class level, a. the array must also be created at the class level for the class methods to use it b. the size of the array is determined at the class level C. the array is available to some of the class methods but not all d. the array is created at the method level when the size is determined 2 pTo write an application that uses recursion to solve a problem. Details: Create a class called Power that computes the value of base exponent. The class should have one recursive method: • public static int power(int base, int exponent) – Which computes the value of base exponent using recursion, returning the result. The recursion step should use the following relationship base exponent = base x base exponent - 1 and the termination condition should occur when exponent is equal to 1, because base 1 = base NOTE: For the power method, assume the exponent parameter value is always greater than 0. Create a second class called PowerTest that contains the main method, and tests the Power.power method. The test class does not need to ask for input from the user of the class, nor does it need to do any additional error checking. Upload both source files to Blackboard. Note: Ensure that your program is properly formatted and it follows all Java naming conventions.// This class discounts prices by 10% public class DebugFour4 { public static void main(String args[]) { final double DISCOUNT_RATE = 0.90; int price = 100; double price2 = 100.00; tenPercentOff(price DISCOUNT_RATE); tenPercentOff(price2 DISCOUNT_RATE); } public static void tenPercentOff(int p, final double DISCOUNT_RATE) { double newPrice = p * DISCOUNT_RATE; System.out.println("Ten percent off " + p); System.out.println(" New price is " + newPrice); } public static void tenPercentOff(double p, final double DISCOUNT_RATE) { double newPrice = p * DISCOUNT_RATE; System.out.println"Ten percent off " + p); System.out.println(" New price is " + newprice); } }C# Part 1: In your program, write a method that accepts a positive integer and returns true if the number is a prime number and false otherwise. Note that 2 is the only even prime number. An odd integer is prime if it not divisible by any odd integer less than or equal to the square root of the number. Part2: A prime number whose reversal is also a prime number is called emirp. For example, 11, 13, 79 and 359 are emirps. Write a program that outputs to a ListBox the first 100 emirps. Your program must contain the method from Part 1 that returns true if a number is prime; false otherwise and another method that returns the reversal of a positive number. You can reverse the integer in the following way: • Convert the integer into a string value = num.ToString(); • Use the following code to reverse the integer string newNum = “”; for (int l = value.Length; l > 0; l--) newNum = newNum + value[l-1]; Also, your program should have a TextBox that will accept a positive integer from the…Charge Account ValidationCreate a class with a method that accepts a charge account number as its argument. The method should determine whether the number is valid by comparing it to the following list of valid charge account numbers:5658845 4520125 7895122 8777541 8451277 13028508080152 4562555 5552012 5050552 7825877 12502551005231 6545231 3852085 7576651 7881200 4581002These numbers should be stored in an array. Use a sequential search to locate the number passed as an argument. If the number is in the array, the method should return true, indicating the number is valid. If the number is not in the array, the method should return false, indicating the number is invalid.Write a program that tests the class by asking the user to enter a charge account number. The program should display a message indicating whether the number is valid or invalid.SEE MORE QUESTIONS
