I feel totally depressed. I 've got a lot of syntaxes, but I haven't heard of them yet. I really saw an example of the observer pattern. It's really depressing to see an imitation function. I can't find the following content. dizzy, but it's better

The so-called functor is a class that simulates the function form through the overload () operator.Therefore, we need to clarify two points:1. A function is a class instead of a function;2. the imitation function reloads the () operator so that it

Java comparator and comparable when a collection or array that needs to be sorted is not a purely numeric type, you can typically use comparator or comparable to implement object sorting or custom sorting in a simple way.1.Comparable
