Can one help me in comparable and comparator methods in Java Collections. I am not able to find the difference between these two. How do these methods work internally?
Thanks in advance

Comparable work on default natural sorting order 
comparator work on customize sorting order

comparable present in java.lang package and it contain only one method
compareTo(Object obj)
comarator present in java.util package and it contain two method
compare() and equals method


All wrapper class & string class implements comparable interface.
only implements class on comparator are Collator & RuleBasedCollator
