Diferents between Comparable and Comparator Interfaces

[Milton Ochoa]

Hi everyone,

Can someome explain me the very diferencias between Comparable and Comparator Interfaces.

I know that the Comparable Interface needs to implements the method:
->int compareTo(T o)

And Iknow too that the Comparator Interface needs to implements the method:
->int compare(T o1, T o2)

But I want to know more the very diferencias.

Very thanks

"Comparable" is an adjective. If an object is Comparable, it has the ability to compare itself to some other object.

"Comparator" is a noun. A Comparator is an object with the ability to compare 2 other objects to each other.

Hi,

Comparator interface has to be implemented by the class ,Object of which you want to compare with Other Objects.

But Comparator interface can be implemented by any class and give you power to
compare any two Objects.
