Shuffling a list in Java

I had a list of words which I wanted to shuffle in random order. When I tried swapping random elements of the list, I needed two random numbers and ensure they are not equal. Was taking a lot of time.

But here is a better way

 private ArrayList shuffleWordList(ArrayList wrdList) {  
     ArrayList lst = new ArrayList();  
     ArrayList tempList = (ArrayList) wrdList.clone();  
     int sz = wrdList.size();  
     for (int i = 0; i < sz; i++) {   
        int listSize = tempList.size();   
        int n = random.nextInt(listSize);   
        lst.add(tempList.get(n));//fill random word into new list   
        tempList.remove(n);//remove selected word   
     }   
     return lst;  
  }   

What we are doing here is,

•  Copy the list into a temporary list - tempList
•  Create another empty list- lst
•  Select one random word from temporary list
•  Add this word to new list
•  Remove the word from temporary list

       Repeat the steps n number of times
