    The program will result in a StackOverflowError due to infinite recursion.

    • The 'floating' method is recursively calling itself without a base case to stop the recursion.

    • Inside the do-while loop, i is incremented by 1 and j is decremented by 1.

    • The loop continues until i becomes greater than or equal to j.

    • Since i is incremented before the comparison and j is decremented before the comparison, the loop runs 9 times.

    • Therefore, the output is 9.
