  • Ans. 

    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.

    • Each recursive call multiplies the input parameter by the result of the recursive call with a decremented parameter.

    • This will continue indefinitely until the stack overflows and an error is thrown.

  • Answered by AI
  • Q12. What is the output of this int i=0; int j=10;do{ if(i++ < --j){ } }while(i
  • Ans. 

    The output of the code is 9.

    • The code initializes i as 0 and j as 10.

    • 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.
