Question

Keep in mind this a intro java class

2. Assuming firstNum and secondNum are integer variables that have been declared and initialized, write a code segment that prints "The product of the numbers is negative", "The product of the numbers is positive" or "The product of the numbers is zero", when their product is negative, positive or zero, respectively. The code segment should evaluate between one and four Boolean expressions to give the correct output. Give values for firstNum and secondNum for which your code segment evaluates exactly one two, three and four Boolean expressions. [20 points

/*
 *FileName: Product.java

public class Product {
    public static void main(String[] args) {
        int firstNum=10;
        int secondNum=0;

        int product=firstNum*secondNum;
        if(product>0){
            System.out.println("Product of Number is positive");
        }
        else if(product<0){
            System.out.println("Product of number is negative ");
        }
        else{
            System.out.println("Product of number is zero");
        }
    }
}

output:

"C:Program Files Javaljdk1.8.0144lbinljava" Product of number is zero Process finished with exit code 0
