Question

Explain the code:

1. Exercise 22: Write a program that creates three random double variables a, b, and c and assigns them values between 0 and 1 using the Math.random( ) method mentioned in the preceding exercise. It then does all of the following:

It prints out the three values.

It prints "All are tiny" if all three values are less than 0.5.

It prints out "One is tiny" if exactly one of the three values is less than 0.5.

It prints out "Only two are tiny" if exactly two of the three values are less than 0.5.

it prints if “None is tiny” if none of the values are less than 0.5.

Answer 1

public class ThreeRandom {

    public static void main(String[] args) {
        // Generate three random numbers
        double a = Math.random(), b = Math.random(), c = Math.random();
        // print those random numbers
        System.out.println("Numbers are " + a + ", " + b + " and " + c);
        
        if (a < 0.5 && b < 0.5 && c < 0.5) {    // If all numbers are less than 0.5
            System.out.println("All are tiny"); // print that all are tiny
        } else if((a < 0.5 && b < 0.5) || (b < 0.5 && c < 0.5) || (a < 0.5 && c < 0.5)) {   // if two of these numbers are less than 0.5
            System.out.println("Only two are tiny");    // print that two of them are tiny
        } else if(a < 0.5 || b < 0.5 || c < 0.5) {  // // if only one of these numbers are less than 0.5
            System.out.println("One is tiny");  // print that one of them is tiny
        } else {    // if none of them are less than 0.5
            System.out.println("None is tiny"); // print that none are tiny
        }
    }
}
