I m still not understanding COMPARABLE Interface

[saurabhthard aggarwal]

please give me SIMPLE ,COMPLETE example of Comparable interface.Also its main features.

The reason why you're not getting good answers is because your question is very vague and general. Can you explain in more detail what exactly you don't understand about the Comparable interface?

Did you read the API documentation? What part of it did you not understand? Have a look at The Collections Framework, which explains how collections work, including the Comparable interface.

Try writing some code yourself to find out how it works. If your code doesn't work, post it here and ask questions about it.

a more common problem would be whether to use the java.lang.Comparable interface or the java.util.Comparator interface. The goal of both of these interface is what?? sort object right?

Comparable uses the "compareTo(Object o)" method
Comparator uses the "compare(Object o1, Object o2)" method

If you implement either of these interfaces you normally override the equals and hashCode methods and good idea to override toString too.

Both of the above methods uses the equals method to compare in order to sort that object.

Talking about sort, using Collection.sort() only sort strings and primitive collections. More complicated objects would not be appropriate so using either of these is the way to go.

At the end of the day, use Comparable to do simple sorting, otherwise use Comparator to have more control.

Best to is to test out both by sorting the same object.
