# Computed Properties!

I don't clearly understand this challenge!

• How am I supposed to return True if the amount of bars equal zero?
• And false if the amount of bars equals (1-12)?

I find it quite humiliating that I don't even get the question :(

GoKart.java
```class GoKart {
public static final int MAX_BARS = 8;
private String color;
private int barCount;

public GoKart(String color) {
this.color = color;
}

public String getColor() {
return color;
}

public void charge() {
barCount = MAX_BARS;
}
}
```

Through a comparison. You learned about the `==` equal operator back in the Java Basics course which is used to compare two things, using that you can find out if `barCount` is equal to 0.

The result of a comparison is a Boolean value. In other words if the result of a comparison is true (IE the two things are equal in the case of the equal operator) then it will return the boolean `true`, if the result of the comparison is false, then it returns `false`.

So to illustrate:

```boolean example = 5 == 5;
// "example" will equal "true" since 5 is equal to 5

boolean example2 = 5 == 1;
// "example2" will equal "false" since 5 is not equal to 1

// ...

return 5 == 2;
// You can also directly return the result of a comparison, you don't have to assign it to a variable.
```

So all you need to do is return the result of using the equal operator to compare `barCount` to 0. You don't need to explicitly check for values 1-12 since anything other than 0 should return false.

I would recommend you try again with those hints in mind. If you still can't solve it I can post the answer for you.

I am even more ashamed after this answer :(

It's so simple that got me so Mad! passed this coding challenge though o/
