Question

1. Need help with a Java application that will compute tip amounts based on user input. Please let me know what else my code could use. My code is below and I need help formatting the output and calculating the amount paid by each person.

Your application will:

• ask the user for a restaurant name, a waiter/waitress name, a bill amount and the number of people splitting the bill
• calculate 10%, 15% and 20% tips on the bill amount
• calculate the amount paid by each person
• display all input values and the calculated values in table format

A sample run of your application is below (user input is in bold):

Which restaurant?  TGIFridays

What is your server's name? Tony

What is your bill amount? 24.13

How many people in your party? 4

Sample output is below:

Restaurant: TGIFridays

Server: Tony

Original Bill: $24.13

with 10% tip
$26.54
everyone pays: $ 6.64

with 15% tip
$27.75
everyone pays: $6.94

with 20% tip
$28.96
everyone pays: $7.24

import java.util.Scanner;

public class TipCalc
{

public static void main(String [] args)
{

Scanner input = new Scanner(System.in);
double billAmount;
int numOfPeople;
double tip1, tip2, tip3;
double totalAmount1, totalAmount2, totalAmount3 = 0;
  
  
//input
System.out.print("Which restaurant? ");
String restaurant = input.next();
System.out.print("What is your servers name? ");
String server = input.next();
System.out.print("What is your bill amount? ");
billAmount = input.nextDouble();
System.out.print("How many people in your party? ");
numOfPeople = input.nextInt();
  
tip1 = billAmount * .10;
tip2 = billAmount * .15;
tip3 = billAmount * .20;
totalAmount1 = billAmount + tip1;
totalAmount2 = billAmount + tip2;
totalAmount3 = billAmount + tip3;
  
System.out.println("Restaurant: " + restaurant);
  
  
System.out.println("Server: " + server);
  
  
System.out.println("Original Bill: " + billAmount);
System.out.println("With 10% tip: " + totalAmount1 + " | Everyone pays: " / );

System.out.println("With 15% tip: " + totalAmount2 + " | Everyone pays: " / );

System.out.println("With 20% tip: " + totalAmount3 + " | Everyone pays: " / );

}
}

    public static void main(String [] args)
    {

        Scanner input = new Scanner(System.in);
        double billAmount;
        int numOfPeople;
        double tip1, tip2, tip3;
        double totalAmount1, totalAmount2, totalAmount3 = 0;


//input
        System.out.print("Which restaurant? ");
        String restaurant = input.next();
        System.out.print("What is your servers name? ");
        String server = input.next();
        System.out.print("What is your bill amount? ");
        billAmount = input.nextDouble();
        System.out.print("How many people in your party? ");
        numOfPeople = input.nextInt();

        tip1 = billAmount * .10;
        tip2 = billAmount * .15;
        tip3 = billAmount * .20;
        totalAmount1 = billAmount + tip1;
        totalAmount2 = billAmount + tip2;
        totalAmount3 = billAmount + tip3;

        System.out.println("Restaurant: " + restaurant);


        System.out.println("Server: " + server);


        System.out.println("Original Bill: " + billAmount);
        System.out.printf("With 10%% tip: %.2f  | Everyone pays: %.2f\n", totalAmount1, (totalAmount1/numOfPeople));
        System.out.printf("With 15%% tip: %.2f  | Everyone pays: %.2f\n", totalAmount2, (totalAmount2/numOfPeople));
        System.out.printf("With 20%% tip: %.2f  | Everyone pays: %.2f\n", totalAmount3, (totalAmount3/numOfPeople));
    }
}
