In Java, the function-call mechanism supportsthe possibility of having a method call itself. This functionality is known asrecursion. For example, suppose we want to sum the integers from 0 to some valuen: publicintsum(intn){if(n >=1) {returnsum(n -1) + n; }returnn; } There are ...
Example ExplainedWhen the sum() function is called, it adds parameter k to the sum of all numbers smaller than k and returns the result. When k becomes 0, the function just returns 0. When running, the program follows these steps:
Working of Java Recursion In the above example, we have called therecurse()method from inside themainmethod (normal method call). And, inside the recurse() method, we are again calling the same recurse method. This is a recursive call. In order to stop the recursive call, we need to pr...
In the above example,factorial()is a recursive function as it calls itself. When we call this function with a positive integer, it will recursively call itself by decreasing the number. Each function multiplies the number with the factorial of the number below it until it is equal to one. ...
Mutually recursive functions can be turned into a single recursive function by breaking the abstraction boundary between the two functions. In this example, the body of is_odd can be incorporated into that of is_even, making sure to replace n with n-1 in the body of is_odd to reflect the...

Tougher example:Fibonacci function: int fib(int n) { if (n == 0) return 0; if (n == 1) return 1; return fib(n-1) + fib(n-2); } Recursive tree: helps in visualization of recursion call and helps to understand how recursion stored in stack memory. ...

For example, in the computing of factorial of n, the terminating conditions are n = 1 and n = 0, for the function simply returns 1. Every recursive function must have at least one terminating condition. Otherwise, the winding phase never terminates. Once the winding phase is complete, then...
