How do you fix the if statement in java, so that city can equal to multiply different cities
Use the scenario below for help answering 1(A), (B) and (C). This is using Java. The Scenario: You have a class named HeartsPlayer A round of Hearts starts with every player having 13 cards Players then choose 3 cards to “trade” with a player (1st you pass left, 2nd you pass right, 3rd you pass across, 4th you keep) Players then strategically play cards in order to have the lowest score At the end of the round, points are cumulatively totaled for each player. If one player’s total is greater than 100, the game ends and the player with the lowest score wins.

Tackle the problem JAVA FXML Replace the Model of the tile puzzle game with a "stub" for the Model of the concentration game. This stub only needs to specify the size of the game grid at this point (that's why it's called a stub—there's not much functionality yet.) Get the program to display a 4 x 6 blank grid. Hints:- on what to do Need to replace the Model in the starter code with a model that provides logic for the concentration game. It is recommend to keep the same basic methods as the original model, except that you should replace getSide() with getRows() and getColumns() methods. *-------------------------------* package model; import java.util.ArrayList;import java.util.Random; public class TilePuzzle{private String [ ][ ] tiles;private int side; // grid sizeprivate int emptyRow;private int emptyCol;private Random randGen;private int row;private int column;/** constructor* @param newSide grid size*/public TilePuzzle( int newSide ){randGen = new Random(); setUpGame( newSide…
The fields timesGet and timesAvoid should each influence either the score, or the game-over condition, or both. For example, maybe getting something good increases the score, hitting something bad decreases the score, and the game ends after a set amount of time. Or alternatively, maybe getting something good increases the score, and hitting a certain number of bad things ends the game. Or alternatively, maybe the score depends only on how long the user has stayed alive, and the user dies when they've hit more bad things than good things. There are many possibilities here. Complete the getScore method, which should return the current game score. In determining the score, you may use timesGet, timesAvoid, and msElapsed. Then modify updateTitle to show the title of your game. (You're welcome to show other statistics in the title, in addition to the score.) Test that the score now updates correctly, as you play your game and collide with images.
Correct answer will be upvoted else downvoted. Computer science. You have w white dominoes (2×1 tiles, the two cells are hued in white) and b dark dominoes (2×1 tiles, the two cells are shaded in dark). You can put a white domino on the board in case both board's cells are white and not involved by some other domino. Similarly, you can put a dark domino if the two cells are dark and not involved by some other domino. Would you be able to put all w+b dominoes on the board if you can put dominoes both on a level plane and in an upward direction? Input The main line contains a solitary integer t (1≤t≤3000) — the number of experiments. The primary line of each experiment contains three integers n, k1 and k2 (1≤n≤1000; 0≤k1,k2≤n). The second line of each experiment contains two integers w and b (0≤w,b≤n). Output For each experiment, print YES in case it's feasible to put all w+b dominoes on the board and negative, in any case. You might print each letter…
You've decided to test the wifi speed in the classroom at the beginning of every lecture. Create a program that will tell you if the wifi speed over the past 3 classes has increased, decreased, or neither. If the wifi speeds are sorted and increasing, then print out "The wifi is getting faster!". If the wifi speeds are sorted and decreasing, then print out "The wifi is getting slower!". If the wifi speeds are unsorted or if two or more speeds are the same, then print "The wifi speed is changing unpredictably." The user should input 3 non-negative numbers (double) separated by spaces. Sample runs: Enter wifi speeds over the last 3 classes: 162 180 225 The wifi is getting faster! Enter wifi speeds over the last 3 classes: 37.5 21.2 19.9 The wifi is getting slower! Enter wifi speeds over the last 3 classes: 162 135.3 225 The wifi speed is changing unpredictably. Ensure you are doing basic input validation, output Please enter a valid input. if the user inputs a negative wifi speed. Make…

In java Problem: An online grocery store sells items on a web page. A user adds items to a basket and he clicks on the submit button when he completes. The store sells food and electronic items. The electronic items require VAT payment of 15 percentage of their prices. There are packed and lose food. The lose food is measured in weights. User specifies the weight amount or the quantity in his selection of items depending on its type. The price is computed as the product of the price per item or the price per weight and the weight or quantity are given by the user. Write an application that reads a user basket list and produces the bill receipt. Check the given samples of input/output in the figures below. The bill receipt contains the list of item details in decreasing order according to the price computed for each item. Use the selection sort1 to sort the items in the list and do not use java given sort method. Selection sort is an algorithm used to arrange elements in a list. It…
Solution should be avaialble in java
In Java, is there a simple way of doing this without having to use so many If statements? please explain A client wants to purchase drinks for an event they are arranging. Write a program that asks them how much money they have to spend and whether alcohol would be allowed at the event. Then show them their choices from the following list, but 1) only show drinks that they can afford to buy at least 1 of, 2) only show alcoholic drinks if they are allowed at the event, and 3) show how many of each drink they could afford. If the user enters an invalid or negative value for their budget or an invalid response for whether alcohol is allowed, it should indicate an error and let the user try again. The possible drink choices are: Bottle of Water: $0.50 Soda: $1.50 Tea: $3.00 Beer (alcoholic): $5.00 Wine (alcoholic): $20.00
I have been working on writing a java program (that goes with another I just got finished- see below CollegeCourse & Student) that prompts user to put in letter grades (A-F) for 5 different courses for a total of 10 different students. So I need to prompt user to input a student ID, then the 1st course ID, then the grade, then the 2nd course ID- then grade, the the 3rd course ID then grade, then the 4th course ID then grade, then finally the 5th course ID then grade. Then it needs to go through the same thing 10 times (for a total of 10 students). It also says the user is asked to "Enter ID for student #s" where s is an integer from 1 through 10, indicating the student (and I don't really know how to do that but I tried as I googled java); AND "Enter course ID #n, where n is an integer from 1 through 5, indicating the course number. And last it needs to verify for grade entry that only the A, B, C, D, or F are entered.I started writing notes to try to keep track of where thing are…
I am running a hotdog eating contest parameters are; 10 hotdogs to the pack 8 buns to the pack random # of contestants and hotdogs to be eaten. if say 2 contestants eat 3 hotdogs each how many hotdogs and buns will be left over, how many dogs and bun open packs will there be. This must be written up in java code but my algebra is not working.
