Create a program named MealPriceCalculation that prompts users enter a meal price and the tip and then calculate and display the total meal price. The program should have a Main () and then use two overloaded methods of the same name to calculate and display the total meal price twice: the first one accepts a meal price (double) and a tip amount in dollars (double), and the second one accepts a meal price (double) and a tip in percentage (int) of the meal price.

    import java. util. Scanner; public class MealPriceCalculation{ public static void main (String[] args) { Scanner input = new Scanner (System. in); System. out. print ("Enter meal price: "); double meal = input. nextDouble (); System. out. print ("Enter tip: "); double tip = input. nextDouble (); calculatePrice (meal, tip); calculatePrice (meal, (int) tip); } public static void calculatePrice (double meal, double tip) { System. out. println ("Total meal price: $" + (meal + tip)); } public static void calculatePrice (double meal, int tip) { System. out. println ("Total meal price $" + (meal+tip)); } }

    Explanation:

    The solution code is written in Java.

    Overload methods are the methods that share the same name but with different method signature. In this question, we create two overload methods calculatePrice (Line 17-23). One version will accept parameter meal and tip in double type and another will accept parameter meal in double but tip in integer. Both of this method are doing the same job which is just printing the total of meal.

    In the main program, create a Scanner object and use it to prompt user to input meal price and tip (Line 6-10). Next call the calculatePrice method for twice. In the first time, pass meal and tip as double type data to calculatePrice method (Line 12). In the second time, pass meal in double but tip in integer to the method. Only the method with parameter list that match the argument data type will be implemented and output the total meal price.
