BJP4 Exercise 4.16: printPalindrome Write a method called printPalindrome that accepts a Scanner for the console as a parameter, and prompts the user to enter one or more words and prints whether the entered String is a palindrome (i.e., reads the same forwards as it does backwards, like "abba" or "racecar"). If the following Scanner object were declared: Scanner console = new Scanner(System.in);printPalindrome(console); The resulting output for a call where the user types a palindrome would be: Type one or more words: racecar racecar is a palindrome! The output for a call where the user types a word that is not a palindrome would be: Type one or more words: hello hello is not a palindrome. For an added challenge, make the code case-insensitive, so that words like "Abba" and "Madam" will be considered palindromes.
6.27 LAB: Toll calculation Use Java programming. Toll roads have different fees based on the time of day and on weekends. Write a method calcToll() that has three parameters: the current hour of time (int), whether the time is morning (boolean), and whether the day is a weekend (boolean). The method returns the correct toll fee (double), based on the chart below. Weekday Tolls Before 7:00 am ($1.15) 7:00 am to 9:59 am ($2.95) 10:00 am to 2:59 pm ($1.90) 3:00 pm to 7:59 pm ($3.95) Starting 8:00 pm ($1.40) Weekend Tolls Before 7:00 am ($1.05) 7:00 am to 7:59 pm ($2.15) Starting 8:00 pm ($1.10) Ex: The method calls below, with the given arguments, will return the following toll fees: calcToll(8, true, false) returns 2.95calcToll(1, false, false) returns 1.90calcToll(3, false, true) returns 2.15calcToll(5, true, true) returns 1.05 public class LabProgram {public static double calcToll(int hour, boolean isMorning, boolean isWeekend) {/* Type your code here. */ } public static void…
Please help me with this , I am stuck ! PLEASE WRITE IT IN C++ Thanks 1) bagUnion: The union of two bags is a new bag containing the combined contents of the original two bags. Design and specify a method union for the ArrayBag that returns as a new bag the union of the bag receiving the call to the method and the bag that is the method's parameter. The method signature (which should appear in the .h file and be implemented in the .cpp file is: ArrayBag<T> bagUnion(const ArrayBag<T> &otherBag) const; This method would be called in main() with: ArrayBag<int> bag1u2 = bag1.bagUnion(bag2); Note that the union of two bags might contain duplicate items. For example, if object x occurs five times in one bag and twice in another, the union of these bags contains x seven times. The union does not affect the contents of the original bags. Here is the main file: #include <cstdlib>#include <iostream>#include "ArrayBag.h"using namespace std; template…
(Conversions between feet and meters) Write a class that contains the following two methods: /** Convert from feet to meters */ public static double footTOMeter(double foot) /** Convert from meters to feet */ public static double meterToFoot(double meter) The formula for the conversion is: meter = 0.305 * foot foot = 3.279 * meter Write a test program that invokes these methods to display the following tables: Feet Meters Meters Feet 1.0 0.305 20.0 65.574 2.0 0.610 25.0 81.967 ... 9.0 2.745 60.0 196.721 10.0 3.050 65.0 213.115

need help creating this Java Program it has to match the sample run exactly thank you ! Description: 6.7 (Financial application: compute the future investment value) Write a method that computes future investment value at a given interest rate for a specified number of years. The future investment is determined using the formula in Programming Exercise 2.21. Use the following method header: public static double futureInvestmentValue(double investmentAmount, double monthlyInterestRate, int years) For example, futureInvestmentValue(10000, 0.05/12, 5) returns 12833.59. Write a program that prompts the user to enter the investment amount (e.g., 1000) and the interest rate (e.g., 9%) and prints a table that displays future value for the years from 1 to 30, as shown below. First, truncate the future value values to two decimals (See Chapter 2). Then use the System.out.printf() method to format the output (See Chapter 4). Program name: Lab06.java Sample Runs: The amount invested: 1000…
2.13 LAB: Driving cost - methods Write a method drivingCost() with input parameters drivenMiles, milesPerGallon, and dollarsPerGallon, that returns the dollar cost to drive those miles. All items are of type double. If the method is called with 50 20.0 3.1599, the method returns 7.89975. Define that method in a program whose inputs are the car's miles/gallon and the gas dollars/gallon (both doubles). Output the gas cost for 10 miles, 50 miles, and 400 miles, by calling your drivingCost() method three times. Output each floating-point value with two digits after the decimal point, which can be achieved as follows:System.out.printf("%.2f", yourValue); The output ends with a newline. Ex: If the input is: 20.0 3.1599 the output is: 1.58 7.90 63.20 Your program must define and call a method:public static double drivingCost(double drivenMiles, double milesPerGallon, double dollarsPerGallon) Note: This is a lab from a previous chapter that now requires the use of a method. Code Given:…
Hello! I need some help with my Java homework. Please use Eclipse with JavaFX Please add comments on the program so I can understand what the code is doing and learn Don't use Liang's BallPane class. Just draw a Circle. 15.3 (Move the ball) Write a program that moves the ball in a pane. You should define a pane class for displaying the ball and provide the methods for moving the ball left, right, up, and down, as shown in Figure 15.26c. Check the boundary to prevent the ball from moving out of sight completely.
Exercise 8.1 A word is said to be abecedarian if the letters in the word appear in alphabetical order. For example, the following are all 6-letter English abecedarian words. abdest, acknow, acorsy, adempt, adipsy, agnosy, befist, behint, beknow, bijoux, biopsy, cestuy, chintz, deflux, dehors, dehort, deinos, diluvy, dimpsy 1. Describe an algorithm for checking whether a given word (String) is abecedarian, assuming that the word contains only lower-case letters. Your algorithm can be iterative or recursive. Submit Answer! 2. Implement your algorithm in a function called ISAbecedarian() RUN!
4.7: Time Machine Your time machine is capable of going forward in time up to 24 hours. The machine is configured to jump ahead in minutes. To enter the proper number of minutes into your machine, you would like a program that can take a start time (in hours, minutes, and a Boolean indicating AM or PM) and a future time (in hours, minutes, and a Boolean indicating AM or PM) and calculate the difference in minutes between the start and future time. A time is specified in your program with three variables: int hours, minutes; bool isAM; for example, to represent 11:50 PM, you would store: hours = 11,minutes = 50,isAM = false This means that you need six variables to store a start and future time. Write a program that allows the user to enter a start time and a future time. Include a function named computeDifference that takes the six variables as parameters that represent the start time and future time. Your function should return, as an int, the time difference in minutes. for example,…
