Answer / qim2010
The “Comparable” interface allows itself to compare with
another similar object (i.e. A class that implements Comparable
becomes an object to be compared with). The following method
are specified in the interface.
public int compareTo(Object o)
public int compareToIgnoreCase(String str)
The "Comparator" interface is used to compare two different
objects. The following method is specified in the Comparator
interface.
public int compare(Object o1, Object o2)

Answer / rajesh
Comparable interface uses Object's compareTo() to compare
the objects. We have to override the compareTo() method in
order to sort.
Where as Comparator, checks for compare() method. You can
sort based on particular property of the object.
