To check whether a number is negative or positive

Question 3 : Write a program in Java to to check whether a number given by the user is negative or positive.


Java Program :


public class number_type
{
 public static void main(int a)
 {
     if (a>0)
     System.out.println("The number "+a+" is positive");
     if (a<0)
     System.out.println("The number "+a+" is negative");
     if (a==0)
     System.out.println("The number "+a+" is neutral");
 }
}

Explanation : There is a simple logic applied here that if a number is greater than 0, it is positive, if it is less than 0, it is negative, and if it is equal to 0, then it is neutral.

Input : 


(i) a=10


(ii) a=-10


(iii) a=0


Output : 


(i) The number 10 is positive


(ii) The number -10 is negative


(iii) The number 0 is neutral
