Explanation:
The source code, written in Java, and a sample output have been attached to this response. It contains comments explaining certain parts of the code.
A few things to note are;
(i) The Scanner class is imported to allow user's interact with the program. This is done by writing the import statement at the top of the code as follows;
import java.util.Scanner;
(ii) An object of the Scanner class is created to receive inputs from the user. The object is called input and created as follows;
Scanner input = new Scanner(System.in);
(iii) Since the user is expected to enter an integer, the nextInt() method of the Scanner object is used to receive the integer and this is saved in a variable called number. i.e
int number = input.nextInt();
(iv) A number x, is even if its remainder when divided by 2 is 0. i.e
if x % 2 = 0, then x is even. Otherwise it is odd.
The user's input received and saved in a variable called number is then checked using if and else blocks to check if it is even or not and can be written as follows;
if(number % 2 == 0){
System.out.println(number + " is even");
}else {
System.out.println(number + " is odd");
}
