- java Convert the MileConversions program to an interactive application. Instead of assigning a value to the miles variable, accept it from the user as input. The MileConversionsInteractive program accepts the miles value as input. class MileConversionsInteractive { public static void main(String[] args) { // Modify the code below final double INCHES_IN_MILE = 63360; final double FEET_IN_MILE = 5280; final double YARDS_IN_MILE = 1760; double miles = 4; double in, ft, yds; in = miles * INCHES_IN_MILE; ft = miles * FEET_IN_MILE; yds = miles * YARDS_IN_MILE; System.out.println(miles + " miles is " + in + " inches, or " + ft + " feet, or " + yds + " yards"); } }Write an if-else statement for the following: If userTickets is greater than 8, execute awardPoints = 10. Else, execute awardPoints = userTickets. Ex: If userTickets is 14, then awardPoints = 10. 1 import java.util.Scanner; 2 3 public class TicketCounter { public static void main (String [] args) { int awardPoints; int userTickets; 4 6. 7 Scanner scnr = new Scanner(System.in); userTickets 8 9. scnr.nextInt(); // Program will be tested with values: 6 %3D 10 11 /* Your code goes here */ 12 System.out.println(awardPoints); } 13 14 15 }Q: What's a better way to write this? (C#) public string SomeMethod(string OriginalZip) { string zip = "Zip Not Available"; zip = GetZip(zip, OriginalZip); return zip; } private static string GetZip(string zip, string OriginalZip) { int zipLength = (OriginalZip.HasValue) ? OriginalZip.Value.ToString().Length: 0; int NumOf Leading Zeroes = (zipLength > O && zipLength < 5) ? 5 - zipLength: 0; if (OriginalZip.HasValue) { i++) } zip = OriginalZip.Value.ToString(); for (int i = 0; i < NumOf Leading Zeroes; { } zip = "0" + zip; } return zip;

This is for Java. What makes these two codes different? (a) If x = 3, what will the first (code) print out? (b) If x = 3, what will the second (code) print out? (c)If x = 1, what will the first (code) print out? (d) If x = 1, what will the second (code) print out?
- Assign the size of userlnput to stringSize. Ex: if userlnput is "Hello", output is: Size of userInput: 1 import java.util.Scanner; 2 3 public class StringSize { public static void main (String [] args) { Scanner scnr = new Scanner(System.in); String userInput; int stringSize; 4 5 8 9. userInput scnr.nextLine(); %3D 10 11 /* Your solution goes here */ 12 13 System.out.println("Size of userInput: + stringSize); 14 15 return; } 16 17 }8) Now use the Rectangle class to complete the following tasks: - Create another object of the Rectangle class named box2 with a width of 100 and height of 50. Note that we are not specifying the x and y position for this Rectangle object. Hint: look at the different constructors) Display the properties of box2 (same as step 7 above). - Call the proper method to move box1 to a new location with x of 20, and y of 20. Call the proper method to change box2's dimension to have a width of 50 and a height of 30. Display the properties of box1 and box2. - Call the proper method to find the smallest intersection of box1 and box2 and store it in reference variable box3. - Calculate and display the area of box3. Hint: call proper methods to get the values of width and height of box3 before calculating the area. Display the properties of box3. 9) Sample output of the program is as follow: Output - 1213 Module2 (run) x run: box1: java.awt. Rectangle [x=10, y=10,width=40,height=30] box2: java.awt.…using System; class Program { publicstaticvoid PrintBoard() { Console.WriteLine(" X | | "); Console.WriteLine(" | | "); Console.WriteLine(" | O | "); Console.WriteLine(); } publicstaticvoid Main(string[] args) { PrintBoard(); PrintBoard(); PrintBoard(); } } Hello! this program is written in C# to play tic tac toe with the user.

- Intro to Java Instuctions: Design and implement a program that reads a series of 10 integers from the user and prints their average For each of the 10 numbers input from the user: one at a time, prompt the user to enter a number. Then read input from the user as a string. Attempt to convert it to an integer using the "Integer.parseInt" method. If the process throws a "NumberFormatExeption", print an appropriate error message and prompt the user for the number again. Continue prompting and reading in number until 10 valid integers have been read Print "The average is" and then print the average of the 10 numbers Code: import java.util.Scanner; public class Lab1MainClass { public static final int VALUES_TO_READ = 10; public static void main(String[] args) { // local variables int[] values = new int [VALUES_TO_READ]; double average; Scanner scan = new Scanner(System.in); int values Read = 0; // how many numbers the user has given us, a count of where we are String userInput; // read…In JAVA HERE IS SerialNumberTester class: public class SerialNumberTester{public static void main(String[] args){String serial1 = "GHTRJ-8975-AQWR"; // ValidString serial2 = "GHT7J-8975-AQWR"; // InvalidString serial3 = "GHTRJ-8J75-AQWR"; // InvalidString serial4 = "GHTRJ-8975-AQ2R"; // Invalid// Validate serial1.First_Last_SerialNumber sn = new First_Last_SerialNumber(serial1);if (sn.isValid())System.out.println(serial1 + " is valid.");elseSystem.out.println(serial1 + " is invalid.");// Validate serial2.sn = new First_Last_SerialNumber(serial2);if (sn.isValid())System.out.println(serial2 + " is valid.");elseSystem.out.println(serial2 + " is invalid.");// Validate serial3.sn = new First_Last_SerialNumber(serial3);if (sn.isValid())System.out.println(serial3 + " is valid.");elseSystem.out.println(serial3 + " is invalid.");// Validate serial4.sn = new First_Last_SerialNumber(serial4);if (sn.isValid())System.out.println(serial4 + " is valid.");elseSystem.out.println(serial4 + " is…In C++ class rectangleType { public: void setLengthWidth(double x, double y); //Sets the length = x; width = y; void print() const; //Output length and width double area(); //Calculate and return the area of the rectangle (length*width) double perimeter(); //Calculate and return the perimeter (length of outside boundary of the rectangle) private: double length; double width; }; Print out the area of the rectangle.
