java.lang.Object | +--structure.NaturalComparator
Implementation of the Comparator
interface that
provides a compare(java.lang.Object, java.lang.Object)
method that compares two objects using those
objects default compareTo methods.
Example usage:
To print out the equality relationship between two randomly generated integers we could use the following:
public static void main(String[] argv){ Random rand = new Random(); Comparator c = newNaturalComparator()
; //generate two random Integers Integer a = new Integer(rand.nextInt(100)); Integer b = new Integer(rand.nextInt(100)); //print out the proper equality relationship between these integers if(c.compare(a,b)
> 0) System.out.println("A:" + a + " > B:" + b); else if (c.compare(a,b) < 0) System.out.println("A:" + a + " < B:" + b); else System.out.println("A:" + a + " = B:" + b);
