Sorting numbers in an array using java coding

The following program coding helps you to sort the numbers in  ascending and descending order.

class SortString{

 static String arr[]={

"13com50","13com48","13com64","13com41","13com52",

     "13com38","13com55","13com64","13com36","13com57"

                 

                      };

     public static void main(String args[]) {

               for(int j=0;j<arr.length;j++){

                for (int i=j+1;i<arr.length;i++) {

                 if(arr[i].compareTo(arr[j])<0) {

       String t=arr[j];

       arr[j]=arr[i];

       arr[i]=t;

      }

    }

  }

System.out.println("NAMES IN ASCENDING ORDER");

        for(int k =0; k<arr.length; k++)

      System.out.println(arr[k]);

System.out.println("NAMES IN DECENDING ORDER");

for(int k = arr.length-1;k>=0;k--)

            System.out.println(arr[k]);

   }

}

 

OUTPUT:
