Java program to check the number is odd and even.

            Lets us write a program to check the number is odd and even using java program. so first, what are odd numbers? and what are even numbers? How to write the program.

What are odd numbers?

        The numbers which are not divided by 2 or the numbers which has reminder 1, when it is divided by 2 are known as odd numbers

Example:

                1,3,5,7,9...

What are even numbers?

        The numbers which are divided by 2 or the numbers which has reminder 0, when it is divided by 2 are known as even numbers

Example:

                2,4,6,8,10...

Logic for the program.

We have to ways to create program.

01. we are declaring a variable, that variable sound be divided (%) by 2 and that should be equated to 0, so if we have 0 as the reminder then the number is even else odd.

02. In the same way, we are declaring a variable, that variable sound be divided (%) by 2 and that should be equated to 1, so if we have 1 as the reminder then the number is odd else even.

Program to check the number is odd and even.

import java.io.*;

class odd

{

   public static void main(String args[]) throws IOException

     {

       int n;

       InputStreamReader read = new InputStreamReader(System.in);

       BufferedReader in = new BufferedReader(read);

       System.out.println("Enter the number");

       n=Integer.parseInt(in.readLine());

         if(n%2==0)

             System.out.println(" n is even");

else

             System.out.println(" n is odd");

       }

}

Explanation:

• We have given the class name has odd.
• public static void main(String arg[]) refers to add a method i.e array of strong method to the program.
• int n is declaring the variable.
• InputStreamReader read = new InputStreamReader(System.in); we create this object because we need to give the value to variable at the time of execution, this is a one of the way to give value to a variable.
• BufferedReader in = new BufferedReader(read); we create this object because, we need a buffer to store the value of the variable.
• n=Integer.parseInt(in.readLine()) is used to convert array of numbers to primitive integer.
• Now, we have to give condition which satisfies all the above int the logic for the program.
• I choose, if statement to satisfy the condition.
• n%2==0 is the condition.
• System.out.println is used to display the given in output screen(make sure S in System is capital)

Output:

       Compile : javac odd.java

       Run        : java odd

       Enter the number

       5

       n is odd.

      Compile : javac odd.java

       Run        : java odd

       Enter the number

       66

       n is even.
