Yes, this code I used it with String Array, not Char Array...
Thanks a lot for your replies... I really appreciate your help...

I used this loop in selection sort with String array and without using StringBuffer... and it worked fine with me...
public static void selectionSort(String[] array) { for (int i = 0; i < array.length; i++) { int min = i; for (int j = i + 1; j < array.length; j++) { if (array[j].compareTo(array[min])<0) { min = j; } } if (min != i) { String temp = array[i]; array[i] = array[min]; array[min] = temp; } } }
The difference now is that I'm trying to generate Random String using StringBuffer... and it's something new to me Also, I don't know too much about Char arrays...
Help me please!

Hi all,
I'm doing a program which is Selection Sort of an array of String... I want to get a 20 length string consist of letters from a-z and A-Z randomly...
I used String Buffer to get this random string but I'm having problems in doing the selection sort...
This is my code:
import java.util.*; public class SelectionSort { public static Random generator = new Random(); public static void main(String[] args) { char[] array = {'Q','A','a','b','c','L','d','U','K','e','H','f','J','g','T','P','X','h','i','F','j','D','O','k','l','N','m','n','B','o','I','p', 'G','q','Y','V','r','s','C','t','S','u','M','Z','v','w','W','x','y','E','z','R'}; StringBuffer sb = new StringBuffer(); int te=array.length; for(int i=0;i<20;i++) { sb.append(array[generator.nextInt(te)]); } System.out.println("Before sorting:"); for (int i = 0; i < array.length; i++) { System.out.print(array[i]+" "); } //Selection Sort for (int i = 0; i < array.length; i++) { int min = i; for (int j = i + 1; j < array.length; j++) { if (array[j].charAt(array[min])<0) { min = j; } } if (min != i) { char temp = array[i]; array[i] = array[min]; array[min] = temp; } } System.out.println("After sorting:"); for (int i = 0; i < array.length; i++) { System.out.print(array[i]+" "); } }
Any help is greatly appreciated...
