- Q11. Output of this program public static int floating(int x){ return x*floating(x-1); } public static void main(String[] args){ floating(10); }
- 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.
- 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.
