Function/Methods

Java Program to Check whether a Number is Positive, Negative or Zero

public class PositiveOrNegative 

{

    public void check(int number) 

{

if (number > 0) 

{

System.out.println(number + " is a positive number");

} 

else if (number < 0) 

{

System.out.println(number + " is a negative number");

} 

else 

{

System.out.println(number + " is neither positive nor negative");

}

}

}

The method takes an integer 'number' as an argument. 

We use if-else-if decision making statements to decide whether the number is positive or negative. 

The condition 'number < 0' takes care of negative number 

while the condition 'number > 0' takes care of positive numbers. 

If both the above conditions are false, the number is zero.

sample outputs :

Input:

number = 7

Output :

7 is a positive number

Input:

number = -34

Output :

-34 is a negative number

Input:

number = 0

Output :

0 is neither positive nor negative
