How do you check if a number is even in Java?

If a number is evenly divisible by 2 with no remainder, then it is even. You can calculate the remainder with the modulo operator % like this num % 2 == 0 . If a number divided by 2 leaves a remainder of 1, then the number is odd. You can check for this using num % 2 == 1 .

Is function even in Java?

The entered number is then stored in a variable num . Now, to check whether num is even or odd, we calculate its remainder using % operator and check if it is divisible by 2 or not. For this, we use if…else statement in Java. If num is divisible by 2 , we print num is even.

How do you determine if an array is even or odd?

Procedure

1. Declare two integer variables to store odd and even numbers count and initialize them to zero. int odd_count = 0, even_count = 0;
2. Loop through each element of an array and check whether its odd or even.
3. if it’s odd, increment the odd_count variable by 1.
4. else, increment the even_count variable by 1.

How to check if a number is even in Java?

In order to check the number, we have divided the number by 2 if it does not leave any remainder, the number is even and the print statement prints that number. DisplayEvenNumbersExample1.java The following program is slightly different from the above program because we have defined a method that contains the logic to check even number.
