{

   static void bubble_sort(int[] weights){

       int n = weights.length;

       for(int i = 0; i < n; i++){

           for(int j = i + 1; j < n; j++){

               if(weights[i] > weights[j]){

                   int temp = weights[i];

                   weights[i] = weights[j];

                   weights[j] = temp;

               }

           }

       }

   }

public static void main(String[] args) {

    Scanner sc = new Scanner(System.in);

    int[] arr = new int[10];

 System.out.println("Enter weights of all 10 students-");

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

         arr[i] = sc.nextInt();

     }

    System.out.println("BEFORE SORTING");

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

            System.out.print(arr[i] + " ");

        }

        bubble_sort(arr);

    System.out.println("\nAFTER SORTING");

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

            System.out.print(arr[i] + " ");

        }

}
