Recursion in Java is a programming technique where a method calls itself directly or indirectly to solve a problem by breaking it into smaller sub-problems. Each recursive call works on a smaller instance until it reaches a base case, which stops further calls. Without a proper base case, recursion can lead to infinite calls and cause a StackOverflowError.
Example – Factorial Calculation
class Factorial {static int factorial(int n) {if (n <= 1) // base casereturn 1;elsereturn n * factorial(n - 1); // recursive call}public static void main(String[] args) {System.out.println("Factorial of 5 is " + factorial(5));}}Copied!✕CopyOutput: Factorial of 5 is 120
Here, each call reduces n until it reaches 1, then the results are multiplied back up the call stack.
