How do i sort an array of strings by the second char of each string?
<p>I wrote a program that asks users to input names into an array and then the names are sorted in alphabetical order...The program works good but I was wondering if I could sort each of the names entered by the 2nd, 3rd, or 4th character in each string? For example, if the user entered Bob, Dan, and Kris the program should sort them as Dan, Bob, Kris. This is my program that sorts my array of strings by the first letter of the string:</p>

<pre><code>  import java.util.ArrayList;
  import java.util.Arrays;
  import java.util.List;
  import java.util.Scanner;


public class SortingAnArrayOfStrings {




public static void main(String[] args) {


{
     //Ask the user for names to add to the array
     List&lt;String&gt; list=new ArrayList&lt;String&gt;();
     Scanner in=new Scanner(System.in);
     do {
         System.out.println(" The names on the list are "+list);
         System.out.println("Would you like to add another name to the list? (y/n)");

         if (in.next().startsWith("y")) {
             System.out.println("Enter:");
             list.add(in.next());
         }else{break;

        }
     } while (true);
    //display the names that have been added to the array
    System.out.println("The names on the list are "+list);

    //sort the array of names in alphabetical order
    String[] Arr=list.toArray(new String[list.size()]);
    String[] stringArray=new String[Arr.length];

     for(int i=0;i&lt;Arr.length;i++)
     {
         for (int j = i+1; j &lt; Arr.length; j++) {
             if (Arr[i].trim().compareTo(Arr[j].trim())&gt;0) {
                 String temp=Arr[j];
                 Arr[j]=Arr[i];
                 Arr[i]=temp;
             }
         }
         stringArray[i]=Arr[i];
     }

     //display the sorted list of names
     System.out.println("This is the list of names after sorting them in alphabetical order : ");

     for(String ss:stringArray){
         System.out.print(ss + " ");

     }
  }

}
}
