Method Detail

main

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

The main method illustrates the use of a selection sort to sort a small array.

Parameters:

args - not used in this implementation

selectionsort

public static void selectionsort(int[] data,
                                 int first,
                                 int n)

Sort an array of integers from smallest to largest, using a selection sort algorithm.

Parameters:

data - the array to be sorted

first - the start index for the portion of the array that will be sorted

n - the number of elements to sort Precondition: data[first] through data[first+n-1] are valid parts of the array. Postcondition: If n is zero or negative then no work is done. Otherwise, the elements of data have been rearranged so that data[first] <= data[first+1] < ... <= data[first+n-1].

Throws:

java.lang.ArrayIndexOutOfBoundsException - Indicates that first+n-1 is an index beyond the end of the array.
