![Q1. Print all the odd numbers from 1 to a user specifiable upper limit (inclusive) using both
while and for loops
Example,
Please enter a number:
9
Odd numbers from 1 to 9 are:
1
3
5
7
9
HINT: The number 9 should be included!!!
2. Write a program called CheckerBoard that displays the following n×n (n=7) checkerboard
pattern using two nested for-loops.
Solution
Q)1)
Using While Loop:
DisplayOddNumbers.java
import java.util.Scanner;
public class DisplayOddNumbers {
public static void main(String[] args) {
//Declaring variables
int number;
int i=1;
//Scanner object is used to get the inputs entered by the user
Scanner sc=new Scanner(System.in);
//getting the number entered by the user
System.out.println("Please enter a number:");
number=sc.nextInt();
//Displaying the odd numbers using while loop](https://image.slidesharecdn.com/q1-230708024633-4fa30cfb/85/Q1-Print-all-the-odd-numbers-from-1-to-a-user-specifiable-upper-lim-pdf-1-320.jpg)
![System.out.println("Odd numbers from 1 to 9 are:");
while(number>0)
{
//Checking the number is even or odd
if(i%2!=0)
{
System.out.println(i);
}
i++;
number--;
}
}
}
