Question

Write a Java program to input a number. Calculate its square root and cube root. Finally, display the result by rounding it off. Also display the floor and ceil values of the Square root of the number entered by the user​

Answer 1

Code:

import java.util.Scanner;

public class CubeSquareRoots {

   public static void main(String[ ] args) {

       System.out.print("Enter a number - ");

       int number = new Scanner(System.in).nextInt( );

       double squareRoot = Math.sqrt(number),

                    cubeRoot = Math.cbrt(number);

       System.out.println("Square Root - " + Math.round(squareRoot));

       System.out.println("  Ceil  - " + Math.ceil(squareRoot));

       System.out.println("  Floor - " + Math.floor(squareRoot));

       System.out.println("Cube Root - " + Math.round(cubeRoot));

   }

}

Sample I/O:

   Enter a number - 123

   Square Root - 11

      Ceil  - 12.0

      Floor - 11.0

   Cube Root - 5
