In C++, any class that can be three-way compared can be a parameter to instances of std::compare_three_way, std::strong_order, std::weak_order, or std::partial_order. Since Java version 1.5, the same can be computed using the Math.signum static method if the difference can be known without computational problems such as arithmetic overflow ...
