Check whether number is even or odd

To check whether a number is even or odd in Java, you can use the modulus operator (%) to determine the remainder of the number when it is divided by 2.

If the remainder is 0, the number is even; otherwise, it is odd.

Here's an example of how you can use the modulus operator to check whether a number is even or odd:

public class Main {
  public static void main(String[] args) {
    int number = 5;
    if (number % 2 == 0) {
      System.out.println(number + " is even");
    } else {
      System.out.println(number + " is odd");
    }
  }
}

This code defines an int variable number and checks whether it is even or odd using the modulus operator. If the remainder of number divided by 2 is 0, the code prints "5 is even" to the console; otherwise, it prints "5 is odd".

I hope this helps! Let me know if you have any questions.
