Question

Create a java pogram

5) The American College of Sports Medicine recommends
that you maintain your training heart rate during an
aerobic workout. Your training heart rate is computed as
0.7* (220 a) + 0.3 * r, where “a” is age and “r” is the
resting heart rate. Create a Java application that asks the
user for his/her age and resting heart rate, and calculates
the training heart rate.

Answer 1

Here is a Java program that implements the computation of the training heart rate as described:

import java.util.Scanner;

public class TrainingHeartRate {

public static void main(String[] args) {

Scanner sc = new Scanner(System.in);

System.out.print("Enter your age: ");

int age = sc.nextInt();

System.out.print("Enter your resting heart rate: ");

int restingHeartRate = sc.nextInt();

double trainingHeartRate = 0.7 * (220 - age) + 0.3 * restingHeartRate;

System.out.println("Your training heart rate should be between " + trainingHeartRate + " and " + (trainingHeartRate + 10));

}

}

In this program, the user is prompted for their age and resting heart rate using a Scanner object. The training heart rate is then computed using the formula provided, and the result is displayed on the screen.
