write a java program using arrays function for hotel bill calculation?
Sure, here's a step-by-step guide to writing a Java program for hotel bill calculation using arrays:
Step 1: Define the class and import the necessary packages:
```java
import java.util.Scanner;
public class HotelBill {
public static void main(String[] args) {
// Main logic goes here
}
}
```
Step 2: Create a Scanner object to read user input:
```java
Scanner scanner = new Scanner(System.in);
```
Step 3: Prompt the user to enter the number of items on the bill:
```java
System.out.print("Enter the number of items on the bill: ");
int itemCount = scanner.nextInt();
```
Step 4: Declare arrays to store the names, prices, and quantities of the items:
```java
String[] itemNames = new String[itemCount];
double[] itemPrices = new double[itemCount];
int[] itemQuantities = new int[itemCount];
```
Step 5: Use a loop to get the item details from the user:
```java
for (int i = 0; i < itemCount; i++) {
System.out.print("Enter the name of item " + (i+1) + ": ");
itemNames[i] = scanner.next();
System.out.print("Enter the price of item " + (i+1) + ": ");
itemPrices[i] = scanner.nextDouble();
System.out.print("Enter the quantity of item " + (i+1) + ": ");
itemQuantities[i] = scanner.nextInt();
}
```
Step 6: Calculate the total bill amount:
```java
double totalBill = 0;
for (int i = 0; i < itemCount; i++) {
totalBill += itemPrices[i] * itemQuantities[i];
}
```
Step 7: Display the itemized bill and the total amount:
```java
System.out.println("Itemized Bill:");
for (int i = 0; i < itemCount; i++) {
System.out.println(itemNames[i] + "\t$" + itemPrices[i] + "\t" + itemQuantities[i] + "\t$" + (itemPrices[i] * itemQuantities[i]));
}
System.out.println("------------------");
System.out.println("Total Bill: $" + totalBill);
```
Step 8: Finally, close the scanner object:
```java
scanner.close();
```
That's it! You now have a Java program that calculates the hotel bill using arrays.
Sure! Here's an example of a Java program that uses arrays to calculate a hotel bill:
```java
import java.util.Scanner;
public class HotelBillCalculator {
public static void main(String[] args) {
Scanner scanner = new Scanner(System.in);
// Asking the user for the number of items
System.out.print("Enter the number of items in your bill: ");
int numberOfItems = scanner.nextInt();
// Creating arrays to store the item names, quantities, and prices
String[] itemNames = new String[numberOfItems];
int[] quantities = new int[numberOfItems];
double[] prices = new double[numberOfItems];
// Asking the user to enter the details of each item in the bill
for (int i = 0; i < numberOfItems; i++) {
System.out.println("\nItem " + (i + 1) + ":");
System.out.print("Enter the name of the item: ");
itemNames[i] = scanner.next();
System.out.print("Enter the quantity of the item: ");
quantities[i] = scanner.nextInt();
System.out.print("Enter the price of the item: ");
prices[i] = scanner.nextDouble();
}
// Calculating the total bill amount
double totalBill = 0.0;
for (int i = 0; i < numberOfItems; i++) {
totalBill += quantities[i] * prices[i];
}
// Displaying the bill details to the user
System.out.println("\n-------- Bill Details --------");
for (int i = 0; i < numberOfItems; i++) {
System.out.println(itemNames[i] + " x " + quantities[i] + " = $" + (quantities[i] * prices[i]));
}
System.out.println("-----------------------------");
System.out.println("Total Bill: $" + totalBill);
scanner.close();
}
}
```
To run this program, simply copy the code into a Java IDE or text editor, save it with a `.java` extension (e.g., `HotelBillCalculator.java`), and then compile and run it using the Java compiler (`javac`) and the Java Virtual Machine (`java`).
Explanation:
1. The program starts by importing the `Scanner` class from the `java.util` package, which allows user input to be read from the console.
2. Next, the `main` method is defined which is the entry point of the program.
3. The user is prompted to enter the number of items in their bill.
4. Three arrays are created (`itemNames`, `quantities`, and `prices`) with a size equal to the number of items provided by the user.
5. The program then prompts the user to enter the details of each item, including the name, quantity, and price. The values entered by the user are stored in the corresponding arrays.
6. The program then calculates the total bill amount by multiplying the quantities and prices of each item and adding them to the `totalBill` variable.
7. Finally, the program displays the bill details to the user, including the item names, quantities, prices, and the total bill amount.
Note: This is a basic example and does not include error handling or more advanced features.
