Shuffle characters in String

Question

Hy,I'll start with a program i'm dealing with.
I need to shuffle the characters in a String besides the first and last character in some text file for example.
Well i started like this
i put the word in some String
then i make char[] c = s.toCharArray();
then make a list.
List l = Arrays.asList(c);
Collections.shuffle(l);
Of course this doesn't work,i suppose because the list can't take char array,but in doc it is Object[]..My question is:if it is there anyway to shuffle the characters of a String with shuffle method in Collections?

Answer 1

i wroted the program like this:
import java.util.*;
public class TextModifier{
          public static void main(String[] args){
                    StringTokenizer str = new StringTokenizer("Filip je all the best.Love him."," .");
                    String s;
                    String output = "";
                    while(str.hasMoreTokens()){
                              s = str.nextToken();
                              if(s.length() > 3){
                                        char[] c = s.toCharArray();
                                        Character[] ch = new Character[c.length];
                                        for(int i = 0;i < c.length;i++)
                                                  ch[i] = new Character(c);
                                        List l = Arrays.asList(ch);
                                        Collections.shuffle(l);
                              for(Iterator ite = l.iterator();ite.hasNext();){
                                        output += (String)ite.next()+" ";
                    System.out.println(output);
I hope you'll figure out what i wroted ,when i paste it paste like this.:)
Well comiler puts me this:
C:\java>javac TextModifier.java
TextModifier.java:18: cannot find symbol
symbol : variable l
location: class TextModifier
for(Iterator ite = l.iterator();
^
ite.hasNext();){
1 error
Why?
