Can I sort String arrays?

[Ananth Chellathurai]

Is there a way to sort a String array? I am using tree which gives a list of picked nodes through request ParameterValues. I am storing it to a String array. Can I sort these values?

Yes, it is easy since String implements the Comparable interface; you can use s1.compareTo(s2).

So what should I compare to? I just want my string array to be sorted alphabetically.

String words[] = { "Good", "Bad", "Ugly" };
Arrays.sort(words);

If you have special requirements

class test {

public static void main(String[] args) {
String words[] = { "Good", "Bad", "Ugly" };
Comparator<String> best = new Comparator<String>() {
public int compare(String s1, String s2) {
return s2.charAt(1) - s1.charAt(1}
};
Arrays.sort(words);
System.out.println(words[0]);
System.out.println(words[1]);
System.out.println(words[2]);
}
}

Thanks a lot Arul. I will use this in my implementation.

You may want to use String.CASE_INSENSITIVE_ORDER if you want to sort it while ignoring the case.
