public class CrunchifyCheckOddEven {
        
        public static void main(String[] args) {
                int crunchifyNumber;
                crunchifyPrintResult("Let's check it out. Please enter integer number:");
                
                Scanner crunchifyInput = new Scanner(System.in);
                
                // Scans the next token of the input as an int.
                //An invocation of this method of the form nextInt() behaves in
                // exactly the same way as the invocation nextInt(radix), where radix is the default radix of this scanner.
                crunchifyNumber = crunchifyInput.nextInt();
                
                /* An even number is a number that can be divided into two equal groups.
                An odd number is a number that cannot be divided into two equal groups. */
                if (crunchifyNumber % 2 == 0)
                        crunchifyPrintResult("Entered number " + crunchifyNumber + " is even");
                else
                        crunchifyPrintResult("Entered number " + crunchifyNumber + " is odd");
        }
        
        // Simple Print result method to printout console result
        private static void crunchifyPrintResult(String s) {
                System.out.println(s);
        }
        
}

Let’s run it.

Just run above program in Eclipse console or in IntelliJ IDEA and you will see some results like this.

Let's check it out. Please enter integer number:
33
Entered number 33 is odd

Process finished with exit code 0

Let's check it out. Please enter integer number:
