Java - Read Number and Check ODD or EVEN

---

I have given here a java program to read number and check ODD or EVEN. It uses mod (%) operator with 2. If the remainder is 1, then it would be an ODD number otherwise EVEN Number.

import java.lang.*;

import java.util.*;

import java.io.*;

 

 

class Check_ODD_EVEN

{

 

    public static int ReadInteger()

   {

        try

        {

              InputStreamReader input = new InputStreamReader(System.in);

              BufferedReader reader = new BufferedReader(input);

              return Integer.parseInt(reader.readLine());

        }

        catch (Exception e)

        {

 

              e.printStackTrace();

              return 0;

        }

   }

  

   public static void main(String[] args)

   {

         System.out.print("Enter a Number to Check ODD or EVEN: ");

         int number = ReadInteger();

 

         if((number % 2) == 0)

            System.out.format("%d is an EVEN number\n", number);

         else

            System.out.format("%d is an ODD number\n", number);       

   }

}
