Consider the JAVA function given below. 

Java




static  int f(int j){
  int i = 50;
  int k;
  if (i == j){
    System.out.print("something");
    k = f(i);
    return 0;
  }
  else return 0;
}


Which one of the following is TRUE?

(A)

The function returns 0 for all values of j.

(B)

The function prints the string something for all values of j.

(C)

The function returns 0 when j = 50.

(D)

The function will exhaust the runtime stack or run into an infinite loop when j = 50



Answer: (D)

Explanation:

When j is 50, the function would call itself again and again as neither i nor j is changed inside the recursion.

Hence Option (D) is the correct answer.
