Java program to print number series without using any loop

In this article, we will learn how to print a sequence of numbers in Java, ranging from 0 to 15. To do this, we'll use recursion rather than using loops like for loop or while loop. 

Recursion is a programming technique where a method calls itself to perform a sub-operation as necessary.

Problem Statement

Write a Java program to print Number series without using any loop

Output

The numbers without using a loop have been printed below
0,1,2,3,4,5,6,7,8,9,10,11,12,13,14,15,

Java program to print number series without using any loop

Following is the Java code to print Number series without using any loop ?

public class Demo{
   public static void main(String[] args){
      int my_num = 0;
      System.out.println("The numbers without using loop have been printed below");
      print_without_loop(my_num);
   }
   public static void print_without_loop(int my_num){
      if(my_num <= 15){
         System.out.print(my_num +",");
         print_without_loop(my_num + 1);
      }
   }
}

Output

The numbers without using a loop have been printed below
0,1,2,3,4,5,6,7,8,9,10,11,12,13,14,15,

Code Explanation

A class named Demo contains the main function where a variable named ?my_num? is initialized to 0. A function named ?print_without_loop? is called. It is defined further wherein the condition is checked if the number passed is greater than 15, if yes, then the number is printed beginning from 0 and incrementing it after every pass. Once the element 15 is reached, the condition exits.
