Write a method printMultiples that takes two integers x and y as parameters, and prints the numbers between x and x x y skipping by y: Example: printMultiples (5, 4) prints: 5 9 13 17 stops before 20 since 20 = 5 x 4 Use the following method header: public static void printMultiples (int x, int y) Write a main method that asks the user to enter two integers. It then calls the printMultiples passing the two entered numbers as parameters.

Add another public method dblValue() to the Fraction class which returns the double precision approximation value of the fraction. That is, the floating point result of actually dividing numerator by denominator. N.B. this method does not do any display itself, but can be called by a client program to be used in an output statement. Eg: if a client has a fraction frac that represents 1 / 2,then a method call to frac.dblValue() should return the double number 0.5.Use the client program to test this functionality; i.e. provide an outputstatement to display the double value of a fraction. import java.util.ArrayList;import java.util.Scanner; //Define the class Fractionclass Fraction{private int n, d;public Fraction(){//Initialize the valuesthis.n = this.d = 0;}public Fraction(int n, int d){//Initialize the variablesthis.n = n;this.d = d;}//Define the getter function getNum() that returns the numeratorpublic int getNum(){//Returns numeratorreturn n;}//Define the getter function getDen()…
A pentagonal number is defined as n(3n−1) ∕ 2 for n = 1, 2, . . ., etc.. Therefore, the first few numbers are 1, 5, 12, 22, . . . . Write a method with the following header that returns a pentagonal number:public static int getPentagonalNumber(int n) For example, getPentagonalNumber(1) returns 1 and getPentagonalNumber(2) returns 5. In Java, Write a test program that uses this method to display the first 100 pentagonal numbers with 10 numbers on each line. Numbers are separated by exactly one space.
*in java* Write a method printShampooInstructions(), with int parameter numCycles, and void return type. If numCycles is less than 1, print "Too few.". If more than 4, print "Too many.". Else, print "N: Lather and rinse." numCycles times, where N is the cycle number, followed by "Done.". End with a newline. Example output with input 2: 1: Lather and rinse. 2: Lather and rinse. Done. Hint: Declare and use a loop variable. import java.util.Scanner; public class ShampooMethod { /* Your solution goes here */ public static void main (String [] args) {Scanner scnr = new Scanner(System.in);int userCycles; userCycles = scnr.nextInt();printShampooInstructions(userCycles);}}
For this problem you will write a method that computes the number of boxes in a pyramid of boxes based on the number of boxes in the base. The boxes in each layer of the pyramid are stacked directly on top of one another (i.e. not offset between two boxes below). For example, below are shown two pyramids, one with base 5 and one with base 6. [] [][] [][][] [][][][] [][][][][] [][][][][][] Implement and test the computePyramidBoxes() method in the PyramidBoxCount class. When testing the computePyramidBoxes() method you should be sure to have at least one test method for each base case and at least one test method for each recursive case in your program.
Write a method that returns anumber, given an uppercase letter, as follows:public static int getNumber(char uppercaseLetter)Write a test program that prompts the user to enter a phone number as a string. The inputnumber may contain letters. The program translates a letter (uppercase or lowercase)to a digit and leaves all other characters intact. Here are sample runs of the program: Enter a string: 1-800-Flowers ↵Enter1-800-3569377
Suppose that a Scanner object contains a bunch of tokens all on a single line separated by spaces. For example: 100.5 30.4 pizza 56.8 1000.3 8.2 Also suppose that you have a particular item that you know the price of. Let’s use the following example: Kindle: 99.99 Write a static method: public static double priceIsRight(Scanner s, double price) that takes a Scanner and an item price as parameters and returns the bid that is closest to the item price but not greater than the item price. If all bids are greater than the price, return 0.0. If there are no bids (Scanner is empty) return 0.0. You can assume the Scanner is not null. In the above example. 56.8 should be returned, since it is the number that is closest to 99.99 but not over 99.99. Notice that there may be some invalid tokens in the Scanner's input. The above example has pizza as one of its tokens, which is clearly not a valid bid. Your method should throw these tokens away and not consider them as bids. It is probably…

Write a Java Code for the below: A prime number is a number that is evenly divisible only by itself and 1. For example, the number 5 is prime because it can be evenly divided only by 1 and 5. The number 6, however, is not prime because it can be divided evenly by 1, 2, 4, and 6. Write a method named isPrime, which takes an integer as an argument and returns true if the argument is a prime number, or false otherwise. Also write main method that displays prime numbers between 1 to 500.
Write static methods: public static double cubeVolume(double h) : h^3 public static double cubeSurface(double h) : 6h^2 public static double cylinderVolume(double r, double h) : hπr^2 public static double cylinderSurface(double r, double h) : 2rπh+2πr^2 that compute the volume and surface area of a cube with height h, and a cylinder with circular base with radius r and height h. Place them into a class named “Geometry.java”. Then write a program with main class called “Lab7_yourID.java” that prompts the user for the values of r and h, calls the four methods, and prints the results. (Optional) Reconsider your previous solution by implementing classes Cube, and Cylinder separately instead of a single class “Geometry” (part A). Which approach is more object-oriented?
Write a static method called isEven that takes an integer as a parameter and returns true if the integer is even and false otherwise.
Define a method findWinningPrize() that takes one integer parameter as the lottery number, and returns the prize as an integer. The prize is returned as follows: If lottery number is 178 or 286, prize is $6000. If lottery number is 296 or 446, prize is $12000. Otherwise, prize is $0. Ex: If the input is 178, then the output is: 6000
