Test Doubles Between 0 and 1

Write a Java program that accepts two double variables and test if both strictly between 0 and 1 and false otherwise.

Sample Solution:

Java Code:

import java.util.Scanner;

public class Solution {
    public static void main(String[] args) {
        // Creating a Scanner object to take input from the user
        Scanner in = new Scanner(System.in);
        
        // Prompting the user to input the first number
        System.out.print("Input first number: ");
        double n1 = in.nextDouble();
        
        // Prompting the user to input the second number
        System.out.print("Input second number: ");
        double n2 = in.nextDouble();
        
        // Checking if both numbers are greater than 0 and less than 1
        System.out.println(n1 > 0 && n1 < 1 && n2 > 0 && n2 < 1);
    }
} 

Sample Output:

Input first number:  1.25
Input second number:  2.15
false

Input first number:  .55
Input second number:  .75
true
