Can anyone explain me recursive function?

Question

I am newbie, learning java programming.

Answer 1

Recursion is used when you have a big problem and the solution to it is a smaller problem and this goes on. For eg take the factorial problem, to find 5's factorial you need a 4's factorial and to find a 4's factorial you need a 3's factorial and so on until you get your final result.

Answer 3

Recursive function is a function which calls itself repeatedly certain number of times.
For ex: print n to 1 numbers.
void print(int n)
{
if(n>0)
{
System.out.println(n);
print(--n); //recursively calling from n to 0;
}

If n=10, then it prints 10 to 1 numbers
By calling print(10),print(9),print(8)....print(0).

Answer 4

recursive consists of calling the function inside of itself
