Java Program to Print First 10 Odd Natural Numbers

Write a Java program to print first 10 odd natural numbers using for loop.

package NumPrograms;

public class First10OddNaturalNum1 {

	public static void main(String[] args) {
		
		System.out.println("The First 10 Odd Natural Numbers are");
		for(int i = 1; i <= 10; i++) 
		{
			System.out.println(2 * i - 1);
		}
	}
}

This Java program prints the first 10 odd natural numbers using a while loop.

package NumPrograms;

public class First10OddNaturalNum2 {

	public static void main(String[] args) {
		int i = 1;
		
		System.out.println("The First 10 Odd Natural Numbers are");
		
		while( i <= 10) 
		{
			System.out.println(2 * i - 1);
			i++;
		}
	}
}

The First 10 Odd Natural Numbers are

public class First10OddNaturalNum3 {

	public static void main(String[] args) {
		int i = 1;
		
		System.out.println("The First 10 Odd Natural Numbers are");
		
		do
		{
			System.out.println(2 * i - 1);

		} while(++i <= 10);
	}
}
