How can I debug a recursive function in Java?

How can I debug a recursive function in Java?

Debugging a recursive function can be tricky. You can start by adding print statements to track the function's parameters and return values.

What if the function goes into an infinite loop?

If it goes into an infinite loop, check the base case. Ensure that the function eventually reaches a condition that stops the recursion.

Can you give me an example of a recursive function?

Sure! A classic example is the factorial function. Here's a simple implementation: public int factorial(int n) { return (n == 0) ? 1 : n * factorial(n - 1); }.

How do I test this function?

You can test it by calling factorial(5) and checking if the output is 120. You can also use assertions in your tests.
