Write a program to sort a string array !!

// Method-I: (Using our own algorithm)

1. public class SortStringArrayByOwnAlgorithm {
2. public static void main(String[] args) {
3. String s[] = { "Java", "C++", "Python", "ruby", "Perl", "ishaan" };
4. String temp;
5. for (int i = 0; i < s.length; i++) {
6. for (int j = 0; j < s.length-1; j++) {
7. if (s[j].compareTo(s[j+1]) > 0) {
8. temp = s[j];
9. s[j] = s[j+1];
10. s[j+1] = temp;
11. }
12. }
13. }
14. for (String str : s) {
15. System.out.print(str + " ");
16. }
17. }
18. }

Output: C++ Java Perl Python ishaan ruby
