What's the syntax for mod in Java?

Instead of the modulo operator, which has slightly different semantics, for non-negative integers, you can use the remainder operator %. For your exact example:

if ((a % 2) == 0)
{
    isEven = true;
}
else
{
    isEven = false;
}

This can be simplified to a one-liner:

isEven = (a % 2) == 0;

September 3, 2025 - Using the modulo operator, we prevent writeIndex from falling out of the boundaries of the array; therefore, we’ll never get an ArrayIndexOutOfBoundsException. However, once we insert more than QUEUE_CAPACITY items, the next item will overwrite the first. In cases where the dividend is negative, Java returns a negative remainder:

Here is the representation of your pseudo-code in minimal Java code;

boolean isEven = a % 2 == 0;

I'll now break it down into its components. The modulus operator in Java is the percent character (%). Therefore taking an int % int returns another int. The double equals (==) operator is used to compare values, such as a pair of ints and returns a boolean. This is then assigned to the boolean variable 'isEven'. Based on operator precedence the modulus will be evaluated before the comparison.

How to use the Java modulo operator - IONOS

December 18, 2024 - That’s what the Java modulo operator is for. It’s also known as the remainder operator, as it determines and returns the remainder after two numbers are divided. There are various situations in which it is extremely important. The operator can be used, for example, to find out whether a number is even or odd or whether a number is prime.

number % 2 is an expression that can't be evaluated to a boolean by any means.

15.17.3. Remainder Operator %

The binary % operator is said to yield the remainder of its operands from an implied division; the left-hand operand is the dividend and the right-hand operand is the divisor.

https://docs.oracle.com/javase/specs/jls/se12/html/jls-15.html#jls-15.17.3

The modulus operator returns an int, in this case but it could return a double or long depending on the operands. An if statement requires a boolean. So the reason why you can't do if(number % 2) is because there is no boolean. With if(number % 2 == 0) you are checking if the result of the modulo operator is zero, which is a boolean.

r/learnjava on Reddit: What the HELL is a modulo?

October 30, 2016 -

I have a test tomorrow, in the test one of the questions will be to seperate a number from a 3 digit number, say I have 641, I need to know how to print out 6,4 and 1 seperately.

What the hell do I do ? The teacher is so bad I couldn't understand a word she said and neither did my class, we already complained about her but this isn't the issue, the issue is that I have no easy answers on the internet for what the modulo is.

Why does doing (n/100)%10; print out the hundred digit ? I have no idea how this works, please go easy on me.

The modulo operator returns the "remainder" of a division. If you think back to your early days at school, when you first learned dividing using long divisions , you learned that for 14/4 the result is 3 and the remainder is 2. Because "4" fits "3" times in '14", but then you still have a remainder of "2" so that: 14 = 4 x 3 + 2 Now, why do they suggest using the modulo operator to get the different numbers (6, 4, 1). Well, let's start from the right. If we divide 641/10, we know that it fits 64 times inside 641 and the remainder is 1. In java terms this is: int lastDigit = 641 % 10; // 1 Now, you can repeat the same process over and over again, however, we need to "shift" the number a bit. For example, if we want to know the second digit, we first divide 641 by 10, so that we only have 64. Now we can just retrieve the last digit again by using the modulo operator: int secondDigit = 641 / 10 % 10; // = 64 % 10 = 4 Now, you should start to see a system here. You can keep doing this trick over and over again, but in stead of dividing by 10, you divide by 100, 1000, 10000, 100000, ... and you get the next digit every time. In your case, the left digit can be retrieved by using: int firstDigit = 641 / 100 % 10; // = 6 % 10 = 6 In this case, it's pretty "useless" to use the modulo operator, because if you have a number with only 3 digits, dividing by 100 will already yield the left most digit. However, let's say that our number was 1234, then we would get: int digit = 1234 / 100 % 10; // = 12 % 10 = 2

Modulo is the remainder from integer division. 4 / 3 = 1 r 1 4 % 3 = 1
