The given program code is implementing the Bubble Sort algorithm to sort an array of integers in ascending order. Here's a breakdown of how the code works:

1. The main method initializes an array `arr` with some integer values.
2. It then calls the `bubbleSort` method and passes the array `arr` as an argument.
3. Inside the `bubbleSort` method, the variable `n` is assigned the length of the array.
4. The outer loop iterates from 0 to `n - 1`, representing the number of passes needed to sort the array.
5. The inner loop iterates from 0 to `n - i - 1`, comparing adjacent elements and swapping them if they are in the wrong order.
6. If `arr[j]` is greater than `arr[j + 1]`, the two elements are swapped using a temporary variable `temp`.
7. After completing the inner loop for each pass, the largest element is moved to its correct position at the end of the array.
8. Finally, the sorted array is printed using a for-each loop in the main method.

The code appears to be correctly implementing the Bubble Sort algorithm. However, if it fails to sort the array correctly, it could be due to an error in the test case or an issue with the input data. Please provide more information about the expected and actual output, as well as any error messages encountered, so that I can assist you further.
