How do I calculate cube root and square root of a number?

To calculate the cube root and the square root of a double value we can use the Math.cbrt(double a) and Math.sqrt(double a) static method call.

package org.kodejava.example.math;

public class CubeSquareRootExample {

    public static void main(String[] args) {
        double cube = 125.0d;
        double square = 100.0d;

        // Get the cube root of double value
        double cbrt = Math.cbrt(cube);
        System.out.println("Cube root of " + cube + " is " + cbrt);

        // Get the square root of double value
        double sqrt = Math.sqrt(square);
        System.out.println("Square root of " + square + " is " + sqrt);


This snippet will print the following output:

Cube root of 125.0 is 5.0
Square root of 100.0 is 10.0
