examples of bubble sort algorithm in java

calculate the summation of rows, and average of rows:

int[][] numbers = { {3,6,12},
				    {1,3,5,7,9},
				    {7,15},
				    {5,4,9,13,12,7,6},
				    {8,9,11,12} };
		int total;
		int[] avg = new int[5];

		for (int i = 0; i < numbers.length; i++)
		{
			total = 0;
			for(int j = 0; j < numbers[i].length; j++)
				total += numbers[i][j]; 
			avg[i] = total / numbers[i].length;
		}
		sort(avg);
		System.out.println();
		for (int i = 0; i < avg.length; i++)
		{
			System.out.print(avg[i] + " ");
		}
	}
		

	
	//bubble sort:
		public static void sort(int[] array)
		{
			int temp;
				
			for (int i = 0; i < array.length; i++)
			{
				for (int j = i + 1; j < array.length; j++)
				{
					if (array[i] > array[j] )
					{
						temp = array[i];
						array[i] = array[j];	
						array[j] = temp;
					}
				} 	
			}
		}
