Method Summary

Modifier and Type	Method and Description
static void	main(java.lang.String[] args) Reads in a sequence of strings from standard input; mergesorts them (using an optimized version of mergesort); and prints them to standard output in ascending order.
static void	sort(java.lang.Comparable[] a) Rearranges the array in ascending order, using the natural order.
static void	sort(java.lang.Object[] a, java.util.Comparator comparator) Rearranges the array in ascending order, using the provided order.

Method Detail

sort

public static void sort(java.lang.Comparable[] a)

Rearranges the array in ascending order, using the natural order.

Parameters:

a - the array to be sorted

sort

public static void sort(java.lang.Object[] a,
                        java.util.Comparator comparator)

Rearranges the array in ascending order, using the provided order.

Parameters:

a - the array to be sorted

comparator - the comparator that defines the total order

main

public static void main(java.lang.String[] args)

Reads in a sequence of strings from standard input; mergesorts them (using an optimized version of mergesort); and prints them to standard output in ascending order.

Parameters:

args - the command-line arguments
