In Java language, Recursion is a programming technique that the method calls itself is called Recursion, which means that if a program allows the programmer to call a method within in the same function, it’s called Recursion call of the method.
Syntax:-
returntype recursion() { recursion(); /* method calls itself */ }
Example:-
public class Recursion
{
static int Factorial(int n){
if (n == 1)
return 1;
else
return(n * Factorial(n-1));
}
public static void main(String[] args)
{
System.out.println("Factorial of 6 is: "+Factorial(6));
}
}
The programmer has to define exit condition from the Method, if not it will go into an infinite loop.
