Check if a Number is Positive, Negative, or Zero - Java Program

Java

import java.util.Scanner;
 
public class CheckNumberStatus {
    public static void main(String[] args) {
        Scanner sc = new Scanner(System.in);
 
        // Taking user input
        System.out.print("Enter a number: ");
        int num = sc.nextInt();
 
        // Checking conditions
        if (num > 0) {
            System.out.println(num + " is a Positive number.");
        } else if (num < 0) {
            System.out.println(num + " is a Negative number.");
        } else {
            System.out.println("The number is Zero.");
        }
 
        sc.close();
    }
}

Output

 
OUTPUT 1:
Enter a number: 25
25 is a Positive number. 

OUTPUT 2:
Enter a number: -10
-10 is a Negative number.

OUTPUT 3: 
Enter a number: 0
The number is Zero.

Explanation

Step 1: User Input

The user enters any integer value:

int num = sc.nextInt();

Step 2: Condition Check

Positive number
If the number is greater than 0:

num > 0

Negative number
If the number is less than 0:

num < 0

Zero
If both conditions fail, the number must be 0.

Step 3: Output

The program prints whether the number is:
✔ Positive
✔ Negative
✔ Zero

Using if–else if–else ensures only one condition is true and executed.
