大家好我已经解决了最初的问题,但现在它没有正确添加。我不确定该做什么以及我哪里出错了。任何帮助将不胜感激。
Hi guys I have fixed the initial problem but now its not adding up correctly. I am unsure what to do and where I have gone wrong. Any help would be appreciated.
import java.util.Scanner;
import java.util.Scanner;
public class zoo {
public static void main(String [] args){
public class zoo { public static void main(String[] args) {
int quantity, confirm, option, finalTotal;
float childTotal = 0;
float adultTotal = 0;
float seniorTotal = 0;
final double childCost = 18;
final double adultCost = 36;
final double seniorCost = 32.50;
int Option[] = new int[3];
Option[0] = 1;
Option[1] = 2;
Option[2] = 3;
boolean continueLoop = true;
char resume;
switch (option) {
case 1:
childTotal=(int) ((double) quantity*childCost) ;
System.out.println("Total amount for child tickets: $" + childTotal);
break;
case 2:
adultTotal=(int) ((double) quantity*adultCost) ;
System.out.println("Total amount for adult tickets $" + adultTotal);
break;
default:
seniorTotal=(int) ((double) quantity*seniorCost);
System.out.println("Total amount for senior tickets $" + seniorTotal);
break;
}
System.out.println("Do you wish to continue? (Y/N) ");
resume = input.next().charAt(0);
switch (option) {
case 1:
finalTotal=(int) ((double) childCost+childTotal);
System.out.println("Total amount for tickets: $" + finalTotal);
break;
case 2:
finalTotal=(int) ((double) adultCost+adultTotal) ;
System.out.println("Total amount for tickets $" + finalTotal);
break;
default:
finalTotal=(int) ((double) seniorCost+seniorTotal);
System.out.println("Total amount for senior tickets $" + finalTotal);
break;
}

package test;
import java.util.Scanner;

/**
* @param args the command line arguments
*/

final float childCost = 18;
final float adultCost = 36;
final float seniorCost = 32.50F;
boolean continueLoop = true;
Scanner input = new Scanner(System.in);
float childTotal = 0;
float adultTotal = 0;
float seniorTotal = 0;
while (continueLoop) {
int option, confirm=0;
System.out.println("\t @@@@@ Welcome to Zoos Victoria @@@@@");
System.out.println("\t \t MAIN MENU \n");
System.out.println("\t Zoo has the following ticketing options \n");
System.out.println("\t 1 = Child (4-6 yrs)");
System.out.println("\t 2 = Adult (16+ yrs)");
System.out.println("\t 3 = Senior (60+ yrs) \n");
System.out.println("Enter your option:");
option = input.nextInt();
switch (option) {
case 1: {
System.out.println("Enter total No of tickets for Child:");
int quantity = input.nextInt();
childTotal = quantity * childCost;
System.out.println("You are purchasing " + quantity + " child tickets at " + childCost + " each!");
System.out.println("Press 1 to confirm");
confirm = input.nextInt();
if (confirm == 1) {
System.out.println("Total amount for child tickets: $" + childTotal);
}
break;
}
case 2: {
System.out.println("Enter total No of tickets for Adult:");
int quantity = input.nextInt();
adultTotal = quantity * adultCost ;
System.out.println("You are purchasing " + quantity + " adult tickets at " + adultCost + " each!");
System.out.println("Press 1 to confirm");
confirm = input.nextInt();
if (confirm == 1) {
System.out.println("Total amount for adult tickets $" + adultTotal);
}
break;
}
case 3: {
System.out.println("Enter total No of tickets for Senior:");
int quantity = input.nextInt();
seniorTotal = quantity * seniorCost ;
System.out.println("You are purchasing " + quantity + " senior tickets at " + seniorCost + " each!");
System.out.println("Press 1 to confirm");
confirm = input.nextInt();
if (confirm == 1) {

}
break;
}
}
if (confirm != 1) {
System.out.println("Incorrect key!");
}
System.out.println("Do you wish to continue? (Y/N) ");
char resume = input.next().charAt(0);
if (resume != 'y' && resume != 'Y') {
continueLoop = false;
System.out.println("Total amount for child tickets: $" + childTotal);
System.out.println("Total amount for senior tickets $" + seniorTotal);
System.out.println("Total amount for adult tickets $" + adultTotal);
float finalTotal = childTotal + adultTotal + seniorTotal ;
System.out.println("Total amount payable: $ " + finalTotal);
}
}
}
