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

A cashier in a supermarket returns change to customers. Suppose we want to write a program to help the cashier finding the possible combinations of coins that sum up to the change. Assume that the coin units available are 1, 2 and 5 Dollars where there is infinite supply of every coin. Write a method that receive the amount of change to be paid to the customer and then Prints the different combinations by which the change can be paid to the customer. Write a program to test this method. Example: if the change is 7 then the different combinations are: 1 1 1 1 1 1 1, 1 1 1 1 1 2, 1 1 1 2 2, 1 2 2 2, 1 1 5, 2 5,
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

Define a method findTrainTicket() that takes one integer parameter as the person's age traveling by train, and returns the ticket price as an integer. The price is returned as follows: If a person's age is more than 84 or less than 4, price is $7. If a person's age is no more than 56 and at least 17, price is $29. Otherwise, price is $12. Ex: If the input is 85, then the output is: 7 import java.util.Scanner; public class TicketFinder { /* Your code goes here */ public static void main(String[] args) { Scanner scnr = new Scanner(System.in); int travelerAge; travelerAge = scnr.nextInt(); System.out.println(findTrainTicket(travelerAge)); }}
The method convertVolume() has an integer parameter. Define a second convertVolume() method that has two integer parameters. The first parameter is the number of gallons and the second parameter is the number of pints. The method should return the total number of pints. Ex: If the input is 9 2, then the output is: 9 gallons yields 72 pints. 9 gallons and 2 pints yields 74 pints. Note: The total number of pints can be found using (gallons * 8) + pints. 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 import java.util.Scanner; public class VolumeMethods { publicstaticintconvertVolume(intgallons) { returngallons*8; } /* Your code goes here */ publicstaticvoidmain(String[] args) { Scannerscnr=newScanner(System.in); intgallonsUsed; intpintsUsed; inttotalPints1; inttotalPints2; gallonsUsed=scnr.nextInt(); pintsUsed=scnr.nextInt(); totalPints1=convertVolume(gallonsUsed);
