recursion in java

Let’s learn recursion in java.

recursion in java

recursion is a process where a method calls itself infinitely or endlessly.

recursion program in java

recursion makes a java code closely packed. Here’s an example on infinite recursive function.

public class InfiniteRecursiveExample
{
   static void print()
   {  
      System.out.println("helloworld");  
      print();  
   }
   public static void main(String[] args)
   {
      print();
   }
}

Output:

helloworld
helloworld
helloworld
helloworld………
java.lang.StackOverflowError

Now let’s see an example on finite recursive function.

public class FiniteRecursiveExample
{
   static int number = 0;
   static void print()
   {
      number++;
      if(number <= 10)
      {  
         System.out.println("helloworld " + number);  
         print();  
      }
   }
   public static void main(String[] args)
   {
      print();
   }
}

Output:

helloworld 1
helloworld 2
helloworld 3
helloworld 4
helloworld 5
helloworld 6
helloworld 7
helloworld 8
helloworld 9
helloworld 10
