Sort a String Array in JAVA.(Create a string array and sort all the string contained by the array in JAVA)

1 LOGIC: Using Sort Method of Arrays Class
CODING:

import java.util.Arrays;
class SortString
{
 public static void main(String [] args)
  {
    String[] a={"Google","Facebook","Apple","Microsoft","Youtube","Twitter","Snapchat","Instagram","Whatsapp"};
      System.out.println("Before Sorting Array:" + Arrays.toString(a));
         Arrays.sort(a);
    System.out.printf("After Sorting Array :" + Arrays.toString(a));
   }
}

2 LOGIC: Without Using Sort Method of Arrays Class
CODING:

class SortString
{
 public static void main(String [] args)
  {
    String[] a={"Google","Facebook","Apple","Microsoft","Youtube","Twitter","Snapchat","Instagram","Whatsapp"};
    String temp;
    int i,r;
    System.out.println("->Before Sorting List...");
    for(i=0;i<10;i++)
System.out.println(a[i]);
     for(i=0;i<10;i++)
     {
       for(r=i+1;r<10;r++)
        {
          if((int)a[i].charAt(0) > (int)a[r].charAt(0))
         {
             temp=a[i];
             a[i]=a[r];
            a[r]=temp;
          }
        }
     }
  System.out.println("->After Sorting List...");
   for(i=0;i<10;i++)
System.out.println(a[i]);
  }
}
