5,190 PointsI need help with my JAVA project
The purpose of this program that I'm writing is to calculate a user's total daily energy expenditure. However, for some reason, it's giving me a ton of errors regarding my boolean operators and "if-else-if" statements. I feel like I'm missing something obvious, could you guys help? Also, I'm aware that not all of the code is on the format, for some reason, the treehouse pop-up won't let me put it all together, sorry!:

54,967 Points1) You have two closing brackets @ line 41
else if (choice.equalsIgnoreCase("B"))
{
activityFactor = 1.3;
TDEE = userBMR * activityFactor;
}
}
2) I added some additional parentheses so conditions were enclosed and was able to compile and run the program
import java.util.Scanner;
public class TDEE {
public static void main(String [] args){
double activityFactor = 0.0;
double TDEE = 0.0;
Scanner in = new Scanner(System.in);
System.out.print("Please enter your name: ");
String firstName = in.next();
String lastName = in.next();
System.out.println(firstName + " " + lastName);
System.out.print("Please enter your BMR: ");
double userBMR = in.nextDouble();
System.out.println(userBMR);
System.out.print("Please enter your gender (M/F): ");
String userGender = in.next();
System.out.println(userGender);
System.out.println();
System.out.println("Select your Activity Level");
System.out.println("[A] Resting (Sleeping, Reclining)");
System.out.println("[B] Sedentary (Minimal Movement)");
System.out.println("[C] Light (Sitting, Standing)");
System.out.println("[D] Moderate (Light Manual Labor, Dancing, Riding Bike)");
System.out.println("[E] Very Active (Team Sports, Hard Manual Labor)");
System.out.println("[F] Extremely Active (Full-Time Athlete, Heavy Manual Labor)");
System.out.println();
System.out.print("Enter the letter corresponding to your activity level: ");
String choice = in.next();
System.out.println(choice);
if(choice.equalsIgnoreCase("A"))
{
activityFactor = 1.0;
TDEE = userBMR * activityFactor;
}
else if (choice.equalsIgnoreCase("B"))
{
activityFactor = 1.3;
TDEE = userBMR * activityFactor;
}
else if ((choice.equalsIgnoreCase("C")) && (userGender.equalsIgnoreCase("F")))
{
activityFactor = 1.5;
TDEE = userBMR * activityFactor;
}
else if (((choice.equalsIgnoreCase("C")) && (userGender.equalsIgnoreCase("M"))) || ((choice.equalsIgnoreCase("D")) && (userGender.equalsIgnoreCase("F"))))
{
activityFactor = 1.6;
TDEE = userBMR * activityFactor;
}
else if ((choice.equalsIgnoreCase("D")) && (userGender.equalsIgnoreCase("M")))
{
activityFactor = 1.7;
TDEE = userBMR * activityFactor;
}
else if ((choice.equalsIgnoreCase("E")) && (userGender.equalsIgnoreCase("F")))
{
activityFactor = 1.9;
TDEE = userBMR * activityFactor;
}
else if ((choice.equalsIgnoreCase("E")) && (userGender.equalsIgnoreCase("M")))
{
activityFactor = 2.1;
TDEE = userBMR * activityFactor;
}
else if ((choice.equalsIgnoreCase("F")) && (userGender.equalsIgnoreCase("F")))
{
activityFactor = 2.2;
TDEE = userBMR * activityFactor;
}
else if ((choice.equalsIgnoreCase("F")) && (userGender.equalsIgnoreCase("M")))
{
activityFactor = 2.4;
TDEE = userBMR * activityFactor;
}
else
{
System.out.println("You did not choose a valid menu option!");
}
System.out.println();
System.out.print("Name: " + firstName + " " + lastName);
System.out.println(" Gender: " + userGender);
System.out.print("BMR: " + userBMR);
System.out.println(" Activity Factor: " + activityFactor);
System.out.print("TDEE: " + TDEE);
}//end of main method
}//end of class
