# Check Positive or Negative Number in Java In this tutorial, we well learn to check a given number is positive or negative. The problem can be solved using if else statement in java. The logic to check a number whether a given number is positive or negative can be see at the below:

• If a number is greater than zero, it is a positive number.
• If a number is less than zero, it is a negative number.
• If a number equals to zero, it is zero.

## Example: Check Positive or Negative Number in Java

```public class PositiveNegative {
public static void main(String[] args) {
double number = 45.6;
// True when the number is greater than 0
if (number > 0.0) {
System.out.println(number + " is a positive number.");
// True when number is less than 0
} else if ( number < 0.0) {
System.out.println(number + " is a negative number.");
// if both test expression is evaluated to False
} else {
System.out.println(number + " is 0.");
}
}
}
```

The output will be:

```45.6 is a positive number.
```

If you change the number value to any negative number (for example: -45.6), the output will be:

```-45.6 is a negative number.
```
