java program to return if number is even or odd code example

Example 1: Java program to check even or odd number

import java.util.Scanner;
public class FindEvenOrOdd
{
   public static void main(String[] args)
   {
      int a;
      Scanner sc = new Scanner(System.in);
      System.out.println("Please enter a number to check even or odd: ");
      a = sc.nextInt();
      if(a % 2 == 0)
      {
         System.out.println("Entered number is an even number.");
      }
      else
      {
         System.out.println("Entered number is an odd number.");
      }
      sc.close();
   }
}

Example 2: Display even and odd numbers in java using for loop

// even and odd numbers 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();
   }
}
