Question
Select the correct answerWhat will be the output of the following Java program? class recursion { int fact(int n) { int result; if (n == 1) return 1; result = fact(n - 1) * n; return result; } } class Output { public static void main(String args[]) { recursion obj = new recursion() ; System.out.print(obj.fact(1)); } }Options 120301Runtime Error
Solution
The output of the given Java program will be 1.
Here's the step by step explanation:
-
The main method in the Output class creates an object of the recursion class and calls the fact method with the argument 1.
-
The fact method in the recursion class checks if the input number n is equal to 1. If it is, it returns 1.
-
Since the input number is 1, the method returns 1 without going into the recursion.
-
The print statement in the main method prints the returned value, which is 1.
So, the output of the program is 1.
