Modify the NumbersDemo application whose main() method holds two integer variables. Assign values to the variables. In turn, pass each value to methods named displayTwiceTheNumber(), displayNumberPlusFive(), and displayNumberSquared(). Create each method to perform the task its name implies. public class NumbersDemo { public static void main (String args[]) { // Write your code here } public static void displayTwiceTheNumber(int n) { // Write your code here } public static void displayNumberPlusFive(int n) { // Write your code here } public static void displayNumberSquared(int n) { // Write your code here } }

Using Visual Studio , C# Demonstrate the method in an application that lets the user experiment with different values for the formulas terms. Form will have 3 text boxes and labels, a calculate button and an exit button. Text boxes hold future value desired , how many years to grow, and annual interest rate. Calculate button will calculate how much the initial deposit needs to be depending on user input of the 3 text boxes. Write a method named PresentValue. Write a value returning PresentValue method that takes several arguments and computes the presentValue. Write a call to the method that sends the values held in the several variables that have been input. Use the Math.Pow(x,y) method for raising a number to a power in the math. Use a decimal value (not a decimal data type) for annual interest rate. For example: 4% interest rate, must be entered 0.04. Years is also a decimal value. Years is also a decimal value

Please do not give solution in image format thanku Method: addOneMinute() Description: This method adds one minute to the current time. Method Signature: void addOneMinute() Parameters: This method does not take any parameters. Return Value: This method does not return anything. Instructions: Check the value of getMinute(). If it is between 0 and 58 inclusive, add 1 to it and call setMinute() with the new value. If getMinute() is 59, set minutes to 0 by calling setMinute(0), and then call addOneHour() to add one hour to the time. Note: You may change things around in your program, but for now please make this method work with the existing method signatures. ________________________________________________________________________________________________--- /*** Adds one minute*/void addOneMinute() {/**assume you have working getMinute(), setMinute(m), and addOneHour()* Feel free to change these in your program, but for now please get things to work with* these function signatures.* if…
check the Coin class and cointester program below. Write a new method .flipCoins(), that flips two (2) coins: the current coin and the coin passed as a parameter. The method returns the integer addition of the flipSides of both coins. Example, as if used in the CointTester program class:Coin bobCoin = new Coin(); // create Coin object [using Coin() constructor]Coin aliceCoin = new Coin(6); // create Coin object with 6 sidesint combinedFlip = 0; // combined flip value of two coinscombinedFlip = bobCoin.flipCoins(aliceCoin); // flip both coins, returned combinedSystem.out.println ("Flip of two coins: " + combinedFlip); Coin class: import java.util.Random; blic class Coin{private int numSides = 2; private int flipSide = 0;private static int coinCounter = 0; private int uniqueID; /** default constructor for Coin class*/public Coin (){coinCounter++;uniqueID = coinCounter; }/** constructor that sets the sides for Coin class* @param numSides the number of sides of the coin*/public Coin…
In physics, an object that is in motion is said to have kinetic energy. The following formula can be used to determine a moving object’s kinetic energy:KE = 1/2 mv2In the formula KE is the kinetic energy, m is the object’s mass in kilograms, and v is the object’s velocity in meters per second. Create an application that allows the user to enter an object’s mass and velocity and then displays the object’s kinetic energy. The application should have a method named KineticEnergy that accepts an object’s mass (in kilograms) and velocity (in meters per second) as arguments. The method should return the amount of kinetic energy that the object has.
java Temperature Conversions Follow the following methods to get answer Method celsius returns the Celsius equivalent of a Fahrenheit temperature, using the calculation celsius = 5.0 / 9.0 * (fahrenheit - 32); Method fahrenheit returns the Fahrenheit equivalent of a Celsius temperature, using the calculation fahrenheit = 9.0 / 5.0 * celsius + 32; Use methods from part a and b to write application that lets the user either to enter Fahrenheit temps and display the Celsius equivalents or to enter Celsius temperatures and display the Fahrenheit equivalent value. Provide a menu to the user to input 1 for “Fahrenheit to Celsius”, 2 for “Celsius to Fahrenheit”, and 3 for leave program. Use a loop for repetition.
This assigment wants me to: Assume that a gallon of paint covers about 350 square feet of wall space. Create an application with a main() method that prompts the user for the length, width, and height of a rectangular room. Pass these three values to a method that does the following: Calculates the wall area for a room Passes the calculated wall area to another method that calculates and returns the number of gallons of paint needed Displays the number of gallons needed Computes the price based on a paint price of $32 per gallon, assuming that the painter can buy any fraction of a gallon of paint at the same price as a whole gallon Returns the price to the main() method The main() method displays the final price. For example: You will need 2.0 gallons The price to paint the room is $64.0 here is my code and this is all i have so far help please ! import java.util.Scanner; public class PaintCalculator { public static void main (String args[]) { int AreaPerGalllon =…
When an object is falling because of gravity, the following formula can be used to determine the distance the object falls in a specific time period: d = ½ gt2 The variables in the formula are as follows: d is the distance in meters, g is 9.8, and t is the amount of time, in seconds, that the object has been falling. 5.3.1. Create a method: FallingDistance Parameters: t, object’s falling time (in seconds) t may or may not be an integer value! Return value: the distance, in meters, that the object has fallen during that time interval Calculations: Use Math.Pow() to calculated the square in the formula 5.3.2. Demonstrate the method by calling it from a loop that passes the values 1 through 20 as arguments, and displays each returned value. Sample output lines: . . . t = 5, d = 122.5 . . . t = 10, d = 490 . . . Your output should have lines for t=1, t=2, t=3, . . . t=20.
Some Websites impose certain rules for passwords, involving use of certain numbers and special characters. Write a Python program (Console and GUI) that prompts the user to enter a password and displays "valid password" if the rule is follows rules of the company, or "invalid password" otherwise. Write a method or a function for implementing the password checking rules for the method/function as follows: A password must have at least eight characters. A password must consist of only letters and digits. A password must contain at least two digits. Sample 1 Enter a string for password: wewew43x valid password Sample 2 Enter a string for password: 343a invalid password

Hi I like this code but is it possible to incorportate the 3 methods, because i dont see it in the current code - void yourTurn ( ) - This method handles moves made by the user. It displays the game board and asks the user to enter a move. If the move is invalid, it prompts user to enter a valid move again. A valid move refers to one of the empty cells in the board. void machineTurn ( ) - This method handles moves by the computer. One possibility is to search for an empty position in the array and mark it for the computer player main ( ) - The main method controls the game. You will declare an array for the game and make use of the methods that you have written to produce behavior of the Tic-Tac-Toe game. The human player always makes the first move in the game. You should alternate between the human player and the computer. After each move you should check for a winner using the checkWinner method. While there is no winner, you should display the gameboard, ask the user for next…
