# Java - check if number is odd or even

7
points

If a number is divisible by two then it is **even**, otherwise, it is **odd**.

To find reminder in java we use modulo operator `%`

.

Even numbers always end with a digit of **0, 2, 4, 6 or 8**

Odd numbers always end with a digit of **1, 3, 5, 7 or 9**

Examples of **even **numbers:

**2, 4, 6, 8, 10, 12, 14, 16, 18, 20, 22, 24, 26**

Examples of **odd** numbers:

**1, 3, 5, 7, 9, 11, 13, 15, 17, 19, 21, 23, 25, 27**

```
public class JavaCheckIfNumberIsOddOrEven {
public static void oddOrEven(int no) {
if (no % 2 == 0) {
System.out.println(no + " is even number");
} else {
System.out.println(no + " is odd number");
}
}
public static void main(String[] args) {
oddOrEven(4); // 4 is even number
oddOrEven(5); // 5 is odd number
}
}
```

Output:

```
4 is even number
5 is odd number
```
