Write a program that print all even numbers from 0 to a given range using do while loop

import java.util.*;
class even
{
public static void main (String arg[])
{
int a;
System.out.print ("\n\t Enter the number = ");
a=in.nextInt();

do
{
if (a%2==0)
System.out.print ("\n\t "+a);
--a;
}while (a>0);

}
}

Note:
     In this program, body of the loop will be executed till a is greater than 0. As you have
noticed a conditional statement in the body of the loop, this is the actual code in our program
which is checking that either the number is even or odd.
