public class BubbleSort
{

 public void bubbleSort(int[] arr){
     for(int i=0; i<arr.length; i++){
        for(int j=1; j<arr.length; j++){
            if(arr[j]< arr[j-1] ){
                int temp = arr[j];
                arr[j] = arr[j-1];
                arr[j-1] = temp;            
            }
        }
     }

     for(int i=0; i<arr.length; i++)
     {
         System.out.print(arr[i] + " ");
     }
}

        Scanner input = new Scanner(System.in);

        System.out.print("Enter the size of the array: ");
        int n = input.nextInt();
        int[] x = new int[n];

        System.out.print("Enter "+ n +" numbers: ");
        for(int i=0; i<n; i++)
        {
            x[i] = input.nextInt();
        }
