Objective

The objective of this program is to calculate the tip amount for a given bill total and the specified tip percentage. The user will input the total bill amount and the desired tip percentage, and the program will compute the amount to be tipped. This is useful in many real-life scenarios like paying for meals in restaurants or tipping service providers.

Java Code for Tip Calculator

            import java.util.Scanner;

            public class TipCalculator {
                public static void main(String[] args) {
                    // Create a Scanner object to read user input
                    Scanner scanner = new Scanner(System.in);
                    
                    // Prompt the user to enter the bill total
                    System.out.print("Enter the total bill amount: $");
                    double billAmount = scanner.nextDouble();
                    
                    // Prompt the user to enter the tip percentage
                    System.out.print("Enter the tip percentage: ");
                    double tipPercentage = scanner.nextDouble();
                    
                    // Calculate the tip amount
                    double tipAmount = (billAmount * tipPercentage) / 100;
                    
                    // Calculate the total amount including tip
                    double totalAmount = billAmount + tipAmount;
                    
                    // Display the calculated tip and total amount
                    System.out.printf("The tip amount is: $%.2f%n", tipAmount);
                    System.out.printf("The total amount (bill + tip) is: $%.2f%n", totalAmount);
                    
                    // Close the scanner to avoid memory leak
                    scanner.close();
                }
            }

Explanation of the Program

This program uses the Scanner class to take input from the user. The user is prompted to enter the bill amount and the tip percentage. The program then calculates the tip by multiplying the bill amount with the tip percentage, and dividing the result by 100. After calculating the tip, it computes the total amount (bill + tip) and prints both values with proper formatting.
