public class Selection extends Object
Selectionclass provides static methods for sorting an array using selection sort. This implementation makes ~ ½ n2 compares to sort any array of length n, so it is not suitable for sorting large arrays. It performs exactly n exchanges.
This sorting algorithm is not stable. It uses Θ(1) extra memory (not including the input array).
For additional documentation, see Section 2.1 of Algorithms, 4th Edition by Robert Sedgewick and Kevin Wayne.
|Modifier and Type||Method and Description|
Reads in a sequence of strings from standard input; selection sorts them; and prints them to standard output in ascending order.
Rearranges the array in ascending order, using the natural order.
Rearranges the array in ascending order, using a comparator.
public static void sort(Comparable a)
a- the array to be sorted
public static void sort(Object a, Comparator comparator)
a- the array
comparator- the comparator specifying the order
public static void main(String args)
args- the command-line arguments
