Question

in java plz

8.13 LAB 3e: Calculate Energy (1) Write a program that calculates the energy needed to heat water from an initial temperature to a final temperature. Your program should prompt the user to enter the amount of water in kilograms and the initial and final temperatures of the water. The formula to compute the energy Q = M * (finalTemperature - initialTemperature) * 4184 where Mis the weight of water in kilograms, initial and final temperatures are in Celsius, and energy is measured in joules. Here is a sample run: *Note: the values entered are shown under the prompt but are not actually part of the output of the program. Enter the amount of water in kilograms: 55.5 Enter the initial temperature: 3.5 Enter the final temperature: 10.5 The energy needed is 1625484.0

Answer 1

/*
  Java Program to calculate to heat water
 */

import java.util.Scanner;

class Main
{
  public static void main(String[] args)
  {
    double M, finalTemperature, initialTemperature, Q;
    Scanner sc = new Scanner(System.in);

    System.out.println("Enter the amount of water in kilograms:");
    M = sc.nextDouble();

    System.out.println("Enter the initial temperature:");
    initialTemperature = sc.nextDouble();

    System.out.println("Enter the final temperature:");
    finalTemperature = sc.nextDouble();

    Q = M * (finalTemperature - initialTemperature) * 4184;

    System.out.println("The energy needed is: " + Q);

    sc.close();
  }
}
