bubble sort for java ArrayList

public void bubbleSort(java.util.ArrayList aList) {
        int n = aList.size();
        int temp = 0;
        for (int i = 0; i < n; i++) {
            for (int j = 1; j < (n - i); j++) {
                if (aList.get(j - 1) > aList.get(j)) {
                    //swap elements  
                    temp = aList.get(j - 1);
                    aList.set(j-1, aList.get(j));
                    aList.set(j, temp);
                }
            }
        }
    }

Implement the Bubble sort algorithm on the following ArrayList

import java.util.ArrayList;

public class Sort{
    private static ArrayList<String> list = new ArrayList<String>();

    public static ArrayList<String> sortByName(String [] input) {
        String temp;
        for (int i=0; i< input.length; i++){
            for(int j= i; j< input.length-1; j++){
                char first = input[i].charAt(0);
                char sec = input[j +1].charAt(0);
                 if (first < sec)  {
                     temp = input[j +1];
                     input[j +1] = input[i];        
                     input[i] = temp;
                 }
             }
            list.add(input[i]);
         }

        return list;
    }

    public static void main(String[] args) {
        String string[] =  {"Ezen", "Allen" , "Wilker", "Kruden", "Crocket"};
        bubbleSortByName(string);
    }
}
