Display even and odd numbers in java using for loop

Let’s learn to display even and odd numbers in java using for loop.

Display even and odd numbers in java using for loop

In even odd program in java using for loop, first get input (maximum number) from user using nextInt() method of Scanner class. This number is stored in integer variable ‘number’.

Here we are using two for loops, one to display even numbers and another to display odd numbers. In the first for loop using modulus operator we have to check if remainder is zero.

If the remainder is zero then given number is even number. Then in second for loop using the same modulus operator if the remainder is one then given number is odd number. Here’s the even odd program in java using for loop.

import java.util.Scanner;
public class EvenOddUsingForLoop
{
   public static void main(String[] args)
   {
      int a;
      Scanner sc = new Scanner(System.in);
      System.out.println("Enter number(max) to print all even and odd until: ");
      int number = sc.nextInt();
      System.out.println("Even numbers from 1 to " + number + " are: \n");
      for(a = 1; a <= number; a++)
      {
         if(a % 2 == 0)
         {
            System.out.print(a + "\n");
         }
      }
      System.out.println("Odd numbers from 1 to " + number + " are: \n");
      for(a = 1; a <= number; a++)
      {
         if(a % 2 == 1)
         {
            System.out.print(a + "\n");
         }
      }
      sc.close();
   }
}


Output:

Enter number(max) to print all even and odd until: 10
Even numbers from 1 to 10 are:
2
4
6
8
10
Odd numbers from 1 to 10 are:
1
3
5
7
9
