We Keep Coding

How do I initialize a variable in an if else program that combines three choices?

I'm writing a party planner program for a question for class.
I can't initialize my three choices of entertainment, decorations, and food.
Eclipse tells me that I should set all these values to 0. I have to stick to these if else statements because that's what we have learned so far.
Here is my code:
import java.util.Scanner;
public class PartyPlanner {
public static void main(String[] args) {
// TODO Auto-generated method stub
int entertainment;
int decorations;
int food;
int budget = entertainment + decorations + food;
Scanner keyboard = new Scanner(System.in);
System.out.println("For your choices, please type"
+ " in what is contained in the brackets."
+ " We will do the calculations for you.");
System.out.println("Choose entertainment:"
+ " [band] for $400 or " + "[DJ] for $150");
String choice1 = keyboard.nextLine();
if (choice1 == "DJ")
{
entertainment = 400;
}
else if (choice1 == "band")
{
entertainment = 150;
}
System.out.println("Where would you like to buy "
+ "decorations? [school] for $100 or [your own] for $250 ?");
String choice2 = keyboard.nextLine();
if (choice2 == "school")
{
decorations = 100;
}
else if (choice2 == "your own")
{
decorations = 250;
}
System.out.println("Would you like to purchase"
+ " [pizza] for $200 or [sub sandwiches]"
+ " for $250 or [appetizers] for $150?");
String choice3 = keyboard.nextLine();
if (choice3 == "pizza")
{
food = 200;
}
else if (choice3 == "sub sandwiches")
{
food = 250;
}
else if (choice3 == "appetizers")
{
food = 150;
}
System.out.println("You have chosen: " + choice1 +
" and " + choice2 + " and " + choice3);
System.out.println("The total cost of this party"
+ " comes out to:" + budget);
}
}
The problem is
The local variable entertainment, decorations, and food may have not been initalized.

First , you have to make the sum at the end of the code because at first the variables are not initialized yet , and secondly you can assign a value of zero if no choice have been made , like this :
public class PartyPlanner {
public static void main(String[] args) {
// TODO Auto-generated method stub
int entertainment;
int decorations;
int food;
Scanner keyboard = new Scanner(System.in);
System.out.println("For your choices, please type"
+ " in what is contained in the brackets."
+ " We will do the calculations for you.");
System.out.println("Choose entertainment:"
+ " [band] for $400 or " + "[DJ] for $150");
String choice1 = keyboard.nextLine();
if (choice1 == "DJ")
{
entertainment = 400;
}
else if (choice1 == "band")
{
entertainment = 150;
}
else { entertainment = 0; }
System.out.println("Where would you like to buy "
+ "decorations? [school] for $100 or [your own] for $250 ?");
String choice2 = keyboard.nextLine();
if (choice2 == "school")
{
decorations = 100;
}
else if (choice2 == "your own")
{
decorations = 250;
}
else { decorations = 0; }
System.out.println("Would you like to purchase"
+ " [pizza] for $200 or [sub sandwiches]"
+ " for $250 or [appetizers] for $150?");
String choice3 = keyboard.nextLine();
if (choice3 == "pizza")
{
food = 200;
}
else if (choice3 == "sub sandwiches")
{
food = 250;
}
else if (choice3 == "appetizers")
{
food = 150;
}
else { food = 0 ; }
int budget = entertainment + decorations + food;
System.out.println("You have chosen: " + choice1 +
" and " + choice2 + " and " + choice3);
System.out.println("The total cost of this party"
+ " comes out to:" + budget);
}
}

Switch statements gets ignored after my if-else statements

//Scanner
Scanner scan = new Scanner(System.in);
//Variables
double bmi; // Body Mass Index
double weight; // Weight in kilograms
double height; // Height in meters
String[] classification = {"Underweight", "Normal", "Overweight", "Obese"};
System.out.print("Your weight in KG \n");
weight = scan.nextDouble();
System.out.print("Enter height in meters: \n");
height = scan.nextDouble();
bmi = weight / (height * height);
if (bmi < 18.5) {
System.out.print("You're " + classification[0] + "\n");
} else if (bmi < 25) {
System.out.print("You're " + classification[1] + "\n");
} else if (bmi < 30) {
System.out.print("You're " + classification[2] + "\n");
} else {
System.out.print("You're " + classification[3] + "\n");
}
switch (Arrays.toString(classification)) {
case "Underweight":
System.out.println("Underweight");
break;
case "Normal":
System.out.println("Normal");
break;
case "Overweight":
System.out.println("A bit overweighted");
break;
case "Obese":
System.out.println("A bit obese");
break;
default:
System.out.println("Ok");
break;
}
}
output,, my switch statement does not work after the if-else statements. It ignores everything and jumps directly to the default in my switch. While my intentions are to follow up with some text after the if-else. So basically if my calculations show me i'm overweighted than my switch statement must now to jump to case "overweighted" and print out that piece of code.. What am I doing wrong?

The result of Arrays.toString(classification) which is [Underweight, Normal, Overweight, Obese] does not match any switch case.
The solution could be something like this:
String result = null;
if (bmi < 18.5) {
System.out.print("You're " + classification[0] + "\n");
result = classification[0];
} else if (bmi < 25) {
System.out.print("You're " + classification[1] + "\n");
result = classification[1];
} else if (bmi < 30) {
System.out.print("You're " + classification[2] + "\n");
result = classification[2];
} else {
System.out.print("You're " + classification[3] + "\n");
result = classification[3];
}
switch (result) {
case "Underweight":
System.out.println("Underweight");
break;
case "Normal":
System.out.println("Normal");
break;
case "Overweight":
System.out.println("A bit overweighted");
break;
case "Obese":
System.out.println("A bit obese");
break;
default:
System.out.println("Ok");
break;
}

ERROR:
Enter the size is being asked too many times for one pizza

In your main switch code, every case is running the size() method multiple times in the if statements:
if(size()==1)
bill[k] = smallprice[ch-1];
else if(size()==2)
bill[k] = mediumprice[ch-1];
else if(size()==3)
bill[k] = largeprice[ch-1];
You need to run size() once before the switch cases, and save the int value returned by it in a variable which is then checked in the if statements.

Instead of a "do-while" loop in the size function, just use a while loop and it should work.

Unable to get total amount payable [duplicate]

This question already has answers here:
Unable to get total amount
(2 answers)
Closed 4 years ago.
I have designed a program which will rerun when the user enters "y" when asked if they wish to continue. The problem I am having is once the user enters "n" the program is supposed to display the total amount payable from all ticket options purchased. I have spent a couple of weeks stuck on this problem and am unsure of what to do next. I have only included the bottom part of my code. I have also included a photo to show my problem when the program is run.
here is my code:
package cse1pgx_a2;
import java.util.Scanner;
public class CSE1PGX_A2 {
/**

public static void main(String[] args) {
int option, quantity, confirm;
float childTotal = 0;
float adultTotal = 0;
float seniorTotal = 0;
float finalTotal = 0;
final double childCost = 18;
final double adultCost = 36;
final double seniorCost = 32.50;
boolean continueLoop = true;
char resume;
Scanner input = new Scanner(System.in);
while (continueLoop) {
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:" );
quantity=input.nextInt();
System.out.println("You are purchasing " + quantity + " child tickets at " + childCost + " each!");
System.out.println("Press 1 to confirm");

quantity=input.nextInt();
System.out.println("You are purchasing " + quantity + " adult tickets at " + adultCost + " each!");
System.out.println("Press 1 to confirm");
confirm=input.nextInt();
break;

System.out.println("Enter total No of tickets for Senior:" );
quantity=input.nextInt();
System.out.println("You are purchasing " + quantity + " senior tickets at " + seniorCost + " each!");
System.out.println("Press 1 to confirm");
confirm=input.nextInt();
break;
}
if (confirm !=1) {
System.out.println("Incorrect key!");
}
OUTER:
while (confirm == 1) {
switch (option) {
case 1:
childTotal=(int) ((double) quantity*childCost) ;
System.out.println("Total amount for child tickets: $" + childTotal);
break OUTER;
case 2:
adultTotal=(int) ((double) quantity*adultCost) ;
System.out.println("Total amount for adult tickets $" + adultTotal);
break OUTER;
default:
seniorTotal=(int) ((double) quantity*seniorCost);
System.out.println("Total amount for senior tickets $" + seniorTotal);
break OUTER;
}
}
System.out.println("Do you wish to continue? (Y/N) ");
resume = input.next().charAt(0);
if (resume == 'y' || resume == 'Y') {
} else {
continueLoop = false;
switch (option) {
case 1:
finalTotal=(float) ((double) childTotal+adultTotal+seniorTotal) ;
System.out.println("Total amount payable: $ " + finalTotal);
break;
default:
System.out.println("Error");
}
}
}
}
}

I have fixed issues and also updated code for better performance.

switch (option) {

finalTotal+=(double) quantity*childTotal ; //minor change

I wished to play and did not fully understand the problem...so i developed from scratch the application. Suryakant was faster so please accept his answer (if it solves your problem). I simply post this here since i worked on it :-)

improvements are in reading.. i would check first if what i read is character or not..

You have an unconditional break right before the switch in question.
As an aside, I think this is the perfect time to learn about functions and how to use them to make code more modular.
