function to even odd number java code example

Example 1: odd are even in java

import java.util.Scanner;

class CheckEvenOdd
{
  public static void main(String args[])
  {
    int num;
    System.out.println("Enter an Integer number:");

    //The input provided by user is stored in num
    Scanner input = new Scanner(System.in);
    num = input.nextInt();

    /* If number is divisible by 2 then it's an even number
     * else odd number*/
    if ( num % 2 == 0 )
        System.out.println("Entered number is even");
     else
        System.out.println("Entered number is odd");
  }
}

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();
   }
}
