Question
![**2.26 LAB: Expression for calories burned during workout**
The following equation estimates the average calories burned for a person when exercising, which is based on a scientific journal article:
```
Calories = ((Age x 0.2757) + (Weight x 0.03295) + (Heart Rate x 1.0781) − 75.4991) x Time / 8.368
```
Write a program using inputs age (years), weight (pounds), heart rate (beats per minute), and time (minutes), respectively. Output the average calories burned for a person.
Output each floating-point value with two digits after the decimal point, which can be achieved as follows:
```
System.out.printf("%.2f", yourValue);
```
**Example:** If the input is:
```
49 155 148 60
```
the output is:
```
Calories: 736.21 calories
```
**Lab Activity 2.26.1: LAB: Expression for calories burned during workout**
```java
import java.util.Scanner;
public class LabProgram {
public static void main(String[] args) {
// Creating a Scanner object to read input.
Scanner scnr = new Scanner(System.in);
// Reading input values for age, weight, heart rate and time.
int age = scnr.nextInt();
int weight = scnr.nextInt();
int heartRate = scnr.nextInt();
int time = scnr.nextInt();
// Calculating calories burned using the given formula.
double calories = ((age * 0.2757) + (weight * 0.03295) + (heartRate * 1.0781) - 75.4991) * time / 8.368;
// Outputting the result with 2 decimal places.
System.out.printf("Calories: %.2f calories", calories);
}
}
```
This example demonstrates a Java program using the `Scanner` class to take user inputs for age, weight, heart rate, and time, then calculates the calories burned and outputs the result with two decimal places.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2Fd24ca5bc-0bbf-4cdf-b6f8-86f97bbb15f8%2F7c964b85-210f-447d-901e-10f30b02242c%2Fgumebwr_processed.png&w=3840&q=75)
