Method Details

compare

public int compare(Comparable<T> o1,
 Comparable<T> o2)

Compare the two Comparable arguments. This method is equivalent to:

((Comparable)o1).compareTo(o2)

Specified by:

compare in interface Comparator<T extends Comparable<T>>

Parameters:

o1 - the first object

o2 - the second object

Returns:

result of comparison

Throws:
