Interview Questions and Answers Q1. What is recursion in Java ? Core Java
Ans. It's a programming technique wherein the method can call itself. The method call usually involves a different set of parameters as otherwise it would lead to an infinite loop. There is usually a termination check and statement to finally return the control out of all function calls. Help us improve.
