I have to use only Boolean and if statements to determine if a number

  • 0

I have to use only Boolean and if statements to determine if a number is between 141 and 185 and whether it is lower or higher than that number. I am stumped.

double maxHR= 220- Double.parseDouble(yearsOld);        //maximum heart rate
double reserveHR=  maxHR- Double.parseDouble(restingHR);         //heart rate reserve
double upperEndZone= (reserveHR*.85)+Double.parseDouble(restingHR);
double lowerEndZone= (reserveHR*.50)+Double.parseDouble(restingHR);

boolean isTargetRateLow= lowerEndZone<= Double.parseDouble(restingHR) ;

Is there a way to put two operators within one boolean statement? I think that would solve my issue.

    By two operators in one boolean statement do you mean :

    boolean bool = a <= b && c >= d

    As in the AND operator (&&)
