Java Programming Boolean if-else statement

[dellmac]

Looking for some assistance with this. I've been messing with this for hours and can't seem to get it right. Some assistance would be greatly appreciated. What I have below is not correct. Material in green cannot be changed. Thanks!Print "Balloon" if isBalloon is true and isRed is false. Print "Red balloon" if isBalloon and isRed are both true. Print "Not a balloon" otherwise. End with newline.import java.util.Scanner;

public class RedBalloon {
public static void main (String [] args) {
boolean isRed = false;
boolean isBalloon = false;

if (!isBalloon || isRed) {
System.out.println("Balloon");
}

else if (!isBalloon && !isRed) {
System.out.println("Red balloon");
}

else {
System.out.println("Not a balloon");
}

return;
}
}

Hi,

The logical operator "!" is a negation in Java, so you are doing just the opposite you are asked for.

The boolean "!isBalloon" is true if "isBalloon" is false, and vice versa.

My recommendation, check first whether the two booleans are true and print "Red ballon", in this way you will only need to check one boolean in the next if condition, I think that way is easier (Just eliminating one logical operator).

Alright thank you! Your response gave me a great understanding, and I have it now. Really appreciate the assistance!
