In this program, we will learn to code the Java Program to Check if a Number is Positive or Negative. Let’s understand Positive and Negative numbers and How to check if a number is Positive or Negative in Java Programming Language?
In this program, we will take the number as input from the user and we will use the if-else conditional statements and check whether the given number is positive or negative.
Now, let’s see the Java Program to Check if a Number is Positive or Negative.
Java Program to Check if a Number is Positive or Negative
import java.util.*;
public class Main{
public static void main(String[] args){
Scanner sc = new Scanner(System.in);
int num = sc.nextInt();
// Checking Number is Positive or Negative
if(num == 0){
System.out.println("The given number is 0, which neither a Positive number nor a Negative Number.");
} else if(num < 0){
System.out.println("The given number "+num+" is a Negative Number");
} else{
System.out.println("The given number "+num+" is a Positive Number");
}
}
}
Output 1
Enter an Integer : 123
The given number 123 is a Positive NumberOutput 2
Enter an Integer : -11
The given number -11 is a Negative NumberOutput 3
Enter an Integer : 0
The given number is 0, which neither a Positive number nor a Negative Number.How Does This Program Work ?
Scanner sc = new Scanner(System.in);
System.out.println("Enter an Integer : ");
int num = sc.nextInt();
In this program, we take the input of the number from the user using the Scanner Class in Java.
// Checking Number is Positive or Negative
if(num == 0){
System.out.println("The given number is 0, which neither a Positive number nor a Negative Number.");
} else if(num < 0){
System.out.println("The given number "+num+" is a Negative Number");
} else{
System.out.println("The given number "+num+" is a Positive Number");
}
Then, using the if-else-if ladder we check whether the given number is 0, less than 0, or not. If the given number is 0, then we print that the number is neither a positive nor a negative number. If the number is less than 0 then we print the given number as a Negative number otherwise it is a Positive number.
This is the Java Program to Check if a Number is Positive or Negative.
