Java: Accepts three numbers from the user and prints

Java Conditional Statement: Exercise-31 with Solution

Write a program that accepts three numbers from the user and prints "increasing" if the numbers are in increasing order, "decreasing" if the numbers are in decreasing order, and "Neither increasing or decreasing order" otherwise.

Test Data
Input first number: 1524
Input second number: 2345
Input third number: 3321

Sample Solution:

Java Code:

import java.util.Scanner;
public class Exercise31 {
   public static void main(String[] args)
    {
        Scanner in = new Scanner(System.in);
        System.out.print("Input first number: ");
        double x = in.nextDouble();
        System.out.print("Input second number: ");
        double y = in.nextDouble();
       System.out.print("Input third number: ");
        double z = in.nextDouble();
        if (x < y && y < z)
        {
            System.out.println("Increasing order");
        }
        else if (x > y && y > z)
        {
            System.out.println("Decreasing order");
        }
        else
        {
            System.out.println("Neither increasing or decreasing order");
        }
    }
}

Sample Output:

Input first number: 1524                                                                                      
Input second number: 2345                                                                                     
Input third number: 3321

Previous: Write a Java program that accepts three numbers and prints "All numbers are equal" if all three numbers are equal, "All numbers are different" if all three numbers are different and "Neither all are equal or different" otherwise.
Next: Write a Java program that accepts two floating­point numbers and checks whether they are the same up to two decimal places.

Java: Tips of the Day

IsPowerOfTwo

Checks if a value is positive power of two.

To understand how it works let's assume we made a call IsPowerOfTwo(4).

As value is greater than 0, so right side of the && operator will be evaluated.

The result of (~value + 1) is equal to value itself. ~100 + 001 => 011 + 001 => 100. This is equal to value.

The result of (value & value) is value. 100 & 100 => 100.

This will value the expression to true as value is equal to value.

public static boolean isPowerOfTwo(final int value) {
    return value > 0 && ((value & (~value + 1)) == value);
}
