In this tutorial, you will learn to check if the number is even or odd in Java. In this example program, we will divide the number by 2, and if the remainder is zero, it is an even number.
We will use the modulo operator (%) that returns the remainder of the two numbers after division.
Example
public class Test {
public static void main(String[] args) {
int num = 8;
int num2 = 9;
if(num % 2 == 0) {
System.out.println("num is an even number!");
} else {
System.out.println("num is odd number!");
}
if(num2 % 2 == 0) {
System.out.println("num2 is an even number!");
} else {
System.out.println("num2 is odd number!");
}
}
}
Output: num is an even number! num2 is odd number!
This code uses if-else statements to check if two variables, “num” and “num2”, are even or odd numbers by checking the remainder of their division by 2. If the remainder is 0, the variable is even. Otherwise, it is odd. The code then prints a message accordingly.
We can also use the ternary operator to check if the number is even or odd in Java:
public class Test {
public static void main(String[] args) {
int num = 112;
System.out.println(num % 2 == 0 ? true : false);
}
}
Output: true
That was all about how to check if the number is even or odd in Java!
