Your Target Heart Rate is the rate at which your heart should beatto get the max

Question

Your Target Heart Rate is the rate at which your heart should beatto get the maximum benefit
from aerobic exercise. This rate is generally agreed to be 60to 70 percent of your maximal heart
rate. Your maximal heart rate equals 220 minus yourage. Create a program which includes the
following: A main method that asks the user to enter an age and thenumber of heartbeats
counted in one minute. These values should be passed to amethod that will calculate the Target
Heart Rate. The method should return true if the user iswithin his/her Target Heart Rate range
and false if not. The main method or driver should thendisplay a message indicating if the user
is in his/her Target Heart Rate range. Keep prompting andreading in new ages and heart rates
until the user enters a negative value for the age.

Hint: Make the return type boolean because you’ll bereturning true or false, and put two int’s in
the formal parameter list, one for the age and one for the numberof beats. Name your program
Lab8_Ex2.java.

Explanation / Answer

please rate - thanks import java.util.*; public class Lab8_Ex2 { public static void main(String [] args) {Scanner in=new Scanner(System.in); int age, beats; boolean good; System.out.print("Enter your age: "); age=in.nextInt(); while(age>=0)    {System.out.print("Enter the number of heartbeatscounted in one minute: ");    beats=in.nextInt();    good=maximal(age,beats);    if(good)     System.out.println("you are withinyour Target Heart Rate");    else        System.out.println("you arenot within your Target Heart Rate");    System.out.println(" Enter your age: ");     age=in.nextInt();    } System.exit(0); }                public static boolean maximal(int age,int beats)//the code thatfollows? {   double maximal; double uprange,lowrange; maximal=220-age; uprange=maximal*.7; lowrange=maximal*.6; System.out.println("Your maximal hearbeats is "+maximal); System.out.println("With a Target Heart Rate range of "+lowrange+"to "+uprange); if(beats>=lowrange&&beats
