Question

IN JAVA

Methods*: Calorie estimator

Write a method ActivityCalories that takes a string indicating an activity (sit, walk, jog, bike, swim) and duration in minutes (integer), and returns the estimated calories expended (double). Calories per minute for a 150 lb person (source):

sit: 1.4 walk: 5.4 run: 13.0 bike: 6.8 swim: 8.7

If the input is sit 2, the output is

2.8  

Hints:

• Use an if-else statement to determine the calories per minute for the given activity.

• Return the calories per minute times the minutes spent.

GIVEN CODE:

import java.util.Scanner;

public class Main {

/* Write your method here */

public static void main(String[] args) {
Scanner scnr = new Scanner(System.in);
int userMinutes;
String userActivity;
  
userActivity = scnr.next();
userMinutes = scnr.nextInt();
  
System.out.println(ActivityCalories(userActivity, userMinutes));
}
}

Answer 1

#source code:

import java.util.Scanner;

public class Main {

public static double ActivityCalories(String userActivity,int userMinutes){

if(userActivity.equals("sit")){

return userMinutes*1.4;

}else if(userActivity.equals("walk")){

return userMinutes*5.4;

}else if(userActivity.equals("run")){

return userMinutes*13.0;

}else if(userActivity.equals("bike")){

return userMinutes*6.8;

}else if(userActivity.equals("swim")){

return userMinutes*8.7;

}

return 0;

}

public static void main(String[] args) {

Scanner scnr = new Scanner(System.in);

int userMinutes;

String userActivity;

userActivity = scnr.next();

userMinutes = scnr.nextInt();

System.out.println(ActivityCalories(userActivity, userMinutes));

}

}
