The following program is written by me. By comparing the program given online, i found no errors. But still when i run this program in command window , it gives error. Hope you will help me with this . Thanks.

class even{
  public static void main(String args[]) 
  {
   int num;
   System.out.println("Enter a number ");
   Scanner in =new Scanner(System.in);
   num=in.nextInt();
   if(num % 2 == 0 )
   {System.out.println("Entered number is even!!");}
   else
   System.out.println("Number is odd!");
 }
}

Hello, welcome to the Ranch!

You don't say what the error is? Can you give some more information on that?

I tested your code in Eclipse and got output. There was no error.

output from your code

Enter a number 
5
Number is odd!

Enter a number 
6
Entered number is even!!

Welcome again

Please show how you imported Scanner.

S Ry, did the Eclipse do the auto-import thing?

The code, as posted by OP won't compile as the compiler wouldn't know what Scanner is.

The error is marked at the Scanner part...do we have to add anything for the compiler to be aware with the Scanner term??

You have to add a line:

import java.util.Scanner;

at the top of your source file.

Apart from mentioned issue, there are still many issues left in your code. Have a look how the code formatting and indentation should be looking like. I also did some other amendments (added comments)

import java.util.Scanner;

class Even // class name starts with an Upper case
{ // this brace is consistent now with the rest of code
    public static void main(String[] args) // [] placed after data type, follow that
    {
        int num;
        System.out.println("Enter a number ");
        Scanner in = new Scanner(System.in);
        num = in.nextInt();

        if(num % 2 == 0) // fixed braces location
        {
            System.out.println("Entered number is even!!");
        }
        else // added missing braces, don't omit them ever
        {
            System.out.println("Number is odd!");
        }
    }
}
