print first 10 natural number in java( 2 approaches)

In this article you can learn how to write java program to print first 10 natural numbers with 2 different approaches.

Approach:-1 "print natural number in java using for loop"

public class usingForLoop 

{

    public static void main(String[] args)

    {

      for(int i = 1; i <= 10; i++)

      {

        System.out.print(i+" ");

      }

    }

}

Explanation

In the for loop, loop is started from 1 and it will go upto 10 and each iteration the value of i is incrementing by 1. 

So for first iteration it will print 1 and then in 2nd iteration the value of i will be incremented and become 2 and will printed.

Like this all 10 natural numbers will displayed in the output screen.

Output

Approach:-2 "display first 10 natural number in java using while loop"

 
public class usingWhileLoop 

{

    public static void main(String[] args)

    {

      int n = 1;

      System.out.println("using while loop");

      while(n < 11)

      {

        System.out.print(n + " ");

        n++;

      }

    }

}

Explanation

In while loop the logic remain same but here we have to declare the variables outside of the loop and we have to increament the value inside the loop.
