Implement Comparator for primitive boolean type?

comparator, java, primitive-types

Solution

You can look up how it is implemented for the `java.lang.Boolean`, since that class, naturally, uses a primitive boolean as well:

public int compareTo(Boolean b) {
    return (b.value == value ? 0 : (value ? 1 : -1));
}

As of Java 7 you can simply use the built-in static method `Boolean.compare(a, b)`.

Problem

I need some classes `implements Comparator`, and for one I want to compare primitive `boolean` (not `Boolean`) values. IF it was a Boolean, I would just `return boolA.compareTo(boolB);` which would return 0, -1 or 1. But how can I do this with primitives?
