Check integer number is positive, negative, zero in java (example)

• Given a integer number, check given number is positive. negative or zero.
• If the input number is greater than zero then it’s positive number
• or If input number is less zero then it’s termed as negative number
• or if input number is neither positive nor negative then it’s zero

Examples to check integer number is positive, negative or zero

Example 1 : Check input number 27 is positive, negative or zero

As input number 27 is greater than so it's positive number

Output of program would be "Number is positive"

Example 2 : Check input number -9 is positive, negative or zero

As input number is less than zero 0 so it's negative number

Output of program would be "Number is Negative"

Program: Check input number is positive negative or zero in Java

package org.learn.beginner;

import java.util.Scanner;

public class PositiveNegativeDemo {

    public static void main(String[] args) {

        try (Scanner scanner = new Scanner(System.in)) {
            System.out.print("Enter input number: ");
            int inputNumber = scanner.nextInt();

            if (inputNumber < 0) {
                System.out.printf("Input number %d is a negative number", inputNumber);
            } else if (inputNumber > 0) {
                System.out.printf("Input number %d is a positive number", inputNumber);
            } else {
                System.out.println("Input number is zero");
            }

        }
    }
}

Output: positive negative or zero number in java

Enter input number: 27
Input number 27 is a positive number
